Fellow Atmos Vacuum Canister Frequen

Your Atmos Vacuum Canister FAQs Answered

By | Coffee, Design

The coffee supply chain is long and loving. The number of people who play a role in getting your favorite coffee beans to your kitchen is truly extraordinary. We created Atmos Vacuum Canister to be the final bit of love in this chain before you brew. By simply twisting the lid back and forth, Atmos sucks air out to prevent oxidation and extends coffee’s shelf life by up to 50%. The care put into each and every bag of coffee can now last longer.

Since Atmos is a new technology, we’re sure you have a few lingering questions you need answering before bringing it home. We combed our social media comments and customer service emails to round up the most frequently asked questions:

What exactly is a “vacuum canister”? I thought my coffee bag was airtight!
First off, let’s define what a vacuum is. A vacuum is a closed system in which pressure is less than atmospheric. In order for this to happen, you need a constant amount of space (i.e. a rigid container) where air particles are removed. There’s a lot of airtight containers/bags out there that get rid of some air, but these aren’t necessarily a true vacuum. An easy way to tell if you don’t have a vacuum container is if your container shrinks (i.e. is it a bag or does it have a lid that collapses into the container). If your container shrinks, it is not a vacuum and will not decrease the pressure below atmospheric.

Uhh Fellow, Atmos is definitely not the first vacuum canister on the market. What makes Atmos “special”?
Unlike other vacuum canisters, Atmos does not have an external pump or part that attaches and detaches. The magic of Atmos is all in the lid. This makes removing air from Atmos super simple. Also, the vacuum mechanism in Atmos is so strong that it reduces internal pressure down to half an atmosphere. In fact, pressure is so important to coffee freshness that we wrote a full blog post on it.

Since Atmos is a sealed environment, will this mean there is a buildup of CO2?
Commercial coffee bean bags with CO2 degassing valves are designed to relieve CO2 pressure build-up and prevent bag rupture, not to necessarily keep coffee fresher for longer. In a vacuum chamber, the pressure is low enough that CO2 buildup is not a concern. CO2 in the air around the beans is non-reactive and will not affect the flavor of the coffee. CO2 does, however, affect your coffee’s flavor once you start brewing, so make sure to bloom your bed of grounds before brewing!

How much coffee does each Atmos hold?
Atmos is available in three sizes. The .4 L Atmos holds up to 6 oz of coffee beans, the .7 L canister holds up to 10 oz of coffee beans, and the 1.2 L canister holds up to 16 oz of coffee beans. But remember, some varietals of coffee beans are bigger than others (looking at you, Pacamara).

Can I store ground coffee in Atmos?
Nope! Powdery or ground substances do not play well with the seals and can clog the intake valve. Since we always advocate for coffee to be ground right before brewing, Atmos was never designed for the intention of storing ground coffee. In addition to ground coffee, please avoid putting any powdery substances inside Atmos such as spices (like turmeric), flours, and matcha tea.

No coffee grinds or powdery substances, got it. What else is good for storing in Atmos besides coffee beans?
The sky’s the limit. Atmos extends the shelf life of your pantry items, too. Toss in loose leaf tea, nuts, cereal, cookies, granola, candy, and other plant-based things you have in your house 😉

Can I put Atmos in the freezer?
You can freeze Atmos, but it’s not the best use of the product. Since coffee beans should be frozen in individual servings as to not refreeze and freeze beans continuously, Atmos doesn’t make the most sense. Atmos is intended to hold multiple servings, so it would be a waste of space in your freezer to put only one serving of beans inside. Also, placing Atmos in the freezer will also eventually reduce the life-span of the vacuum seal.

Why did you make a clear glass Atmos if sunlight is a big contributor to coffee freshness?
If you anticipate storing coffee in your cupboard or a shaded area, clear glass is great! You can see the contents, which is especially important if you’re storing pantry items. But if your brew station is near a window or want to put your Atmos Vacuum Canisters on display, then our matte black stainless steel makes more sense. We think both designs are beautiful, so it comes down to your preference and needs.

I have more than one Atmos. How can I label them to tell the difference?
If you have a clear glass Atmos, you can use chalk pens or whiteboard markers. Both of these options will wash or wipe off. Also, if you have the largest size, you can keep the beans in the bag and put the bag directly inside of Atmos. For the matte black stainless steel, we don’t recommend writing directly onto the body. We love using a strip of washi tape on the bottom.

And lastly, a boring but necessary question. How do I clean my Atmos?
Atmos is not dishwasher safe. When it comes to the lid, please prevent liquid from getting inside and do not clean the lid under running water. Instead, clean with a damp, non-abrasive sponge and use mild soap, if needed. For thorough cleaning, the gasket and filter can be removed and washed separately. Similarly, we recommend hand-washing the stainless steel and glass canister with a damp, non-abrasive sponge and mild soap. Using a coarse sponge, brush or other rough surfaces will scratch the finish of the lid and canister.

If your question didn’t make the list, don’t hesitate to reach out to our customer service team at hello@fellowproducts.com. We’re here to help!

How The World’s Best Brewers and Baristas Prepare For Competition

By | Coffee

Brewers and baristas from near and far will be gathering this weekend in Kansas City for the US Coffee Championships, or CoffeeChamps for short. The road to the national stage is not easy. First comes qualifiers and then onto regionals with hours and hours of practice fit into any and all spare time.

We love supporting competitors. It’s humbling to see the best brewers and baristas in the world use our gear on our stage. If you’re thinking about taking the leap to compete in the future or just curious about what the heck goes into a “coffee competition,” you’ve come to the right place. We spoke with five of this year’s CoffeeChamps competitors to get the inside scoop on their routines and advice for future competitors.

CODY BARNHART | VIENNA COFFEE COMPANY | BREWERS CUP

Cody Barnhart 2019 CoffeeChampsHow did you first get into coffee and what is your role now?
Vienna Coffee Company opened up its first café in my hometown when I was only fourteen. Since their third day open, I was a regular customer for years. I moved to Kansas City for a year or so. Shortly after I moved back to Tennessee in 2016, I got a barista position at their café. Since then, I moved to Lead Barista at our downtown Knoxville location and then onto Sales Account Manager within the company. I still split time between our wholesale business and being on bar, but the bulk of my time is spent trying to help wholesale customers provide the best coffee they can — whether it’s training, coffee offerings, retail strategies, etc.

What were your goals going into the start of the competition season?
My mantra for specialty coffee from day one has been this: “Hospitality and excellence don’t have to be at odds.” Too often, specialty cafés offer hospitality at the expense of excellence (or vice versa). I went into competition season wanted to grow in both service skills and brewing skills — to learn how to talk about excellent coffee without alienating those different than us.

How did you prepare for competition?
For both the qualifying and national events, it took longer than expected to find a roast profile I felt made the coffees shine. The largest chunks of my preparation were unlearning the bad brewing habits I had, taking note of where I needed to “get out of the way,” and learning to be a little less heavy handed in my brewing. My preparation focused on yielding to the coffee, rather than pursuing a specific flavor profile or characteristic. The thing that shined in the El Obraje Caturra I used for qualifiers was its acidity and flavor clarity; the thing that shines in the Cold Fermented Pink Bourbon I’m using from Finca Monteblanco is the sheer complexity. I wanted the coffees to determine the brewing methods because, in brewing, one size doesn’t fit all.

I’ve been mentally preparing and reading up on brewing science since the company decided last April they would ask me to compete. That said, I couldn’t even begin to count the number of hours I’ve spent preparing. My family and friends have to be sick of hearing my tangents about processing and elevation by now!

How are you using Fellow gear in Kansas City?
I’m using two of the matte white Stagg EKGs in my routine, alternating between kettles so that I have more consistency across brews. I love your kettles because they offer unmatched control over brewing temperature. We ought to treat water temperature a bit more dynamically and use it in tandem with grind size. Brewing is a dance, and the Stagg EKGs make me a better dancer.

How did you pick your competition coffee?
I decided pretty early on that I wanted a stellar coffee that was resistant to la roya and didn’t break the bank. I don’t have any qualms with geshas, but they are a bit inaccessible and not completely understood by everyday coffee drinkers. In addition, they’re predominantly lower yield and more delicate plants, driving the price up.

The Pink Bourbon I chose is also, put simply, a fascinating coffee. It isn’t “actually” a Pink Bourbon; it was given the name for commercial reasons. The producers think it’s an escaped seedling from a research farm, but they’re not entirely certain. It was also processed using Cold Fermentation. Rodrigo Sanchez, who operates Finca Monteblanco in Huila, Colombia, began using the process a few years ago. When the coffee has a Brix content of 27-31 degrees, Rodrigo and his team use the Cold Fermentation process to slow down sugar degradation and enable the mucilage to have longer contact time with the bean. It offers a sweetness and complexity like nothing else.

Any advice for folks thinking about dipping their toes into the competition scene for the first time?
Well, first things first: read the rules. Everyone says it, but I’ll say it again. Know what you’re going into. I printed the whole packet and marked it up with highlights and arrows and underlines. Ingrain it in your head. Secondly, cultivate your sensory skills. Evaluate everything you consume (please don’t use a scoresheet – just do it really quick in your head!). I don’t have the most refined pallet, but I noticed an improvement once I started paying attention. It doesn’t even have to be coffee. You can spend some time learning about hops in beer or different types and ages of wines, or flavors in cheeses or unfamiliar spices. I distinctly remember pouring a soda at a friend’s house and prefacing that I would be smelling before I drank it (and asking them not to make fun of me). I looked like a fool, but I think it helped me in the long run.

Lastly, if you compete, have fun with it. It seems like there’s too much competition and condescending spirits in the coffee world. We’re all in this thing together, so if you’re not having fun and growing as a professional because of competition, you might be in it for the wrong reasons.

GRACE MCCUTCHAN |  RED ROOSTER COFFEE ROASTER | BREWERS CUP

Tell us a little about your journey into coffee!
I started in coffee when I was 14 years old. My family opened up a café, and I began working there after school. We knew very little about specialty coffee and coming from a small town in rural Appalachia (Floyd, Virginia) our resources were pretty limited. We experimented most of the time, read online articles, attended trade shows when we could but essentially only had one another to rely on to perfect our craft. Six years later, in 2010, my sister and brother-in-law formed Red Rooster primarily to roast coffee for the café (with bigger ideas and dreams always in the back of their minds). Today, Red Rooster has 31 employees, a thriving flagship café, partner cafés all over the east coast, a premier training lab, a successful tea (Swallowtail Tea) and syrup line (JT Copper Extracts), and an on-site daycare facility for employed working parents. We’ve come quite a long ways, and we did it together relying on one another’s feedback, advice, and pure gut intuition.

What were your goals going into the start of the competition season?
My goal going into this competition was simple: make the best cup of coffee and hit every single sensory note possible. As a first time competitor, I knew very little when it came to the overall structure of the competition, but I wanted to do it so that I might learn more about the industry and the SCA, meet more coffee professionals, and help put Floyd, Virginia and Red Rooster on the map. I also just wanted to have fun and make a good cup of coffee for the judges while telling my story and the coffee’s story. So that’s what I did and what I hope to continue doing!

How did you prepare for Brewers Cup?
I began thinking of a narrative for my presentation 2-3 months before the qualifiers in Nashville and practiced every day in some facet or another leading up to the competition. I already knew which coffee I was going to use so I began thinking of different stories I’d like to tell the judges and the audience and ultimately, settled on something that I believe to be the most authentic and real part of myself. My story, alongside the story of the WORKA cooperative in which this coffee comes from. I’ve changed quite a bit up in my routine in preparation for Kansas City focusing primarily on the many technical aspects within the presentation so that’s been fun and challenging, but I am happy and honored to continue sharing this coffees story as well as my own. Because that’s what it’s all about right? The journey from seed to cup and our belief in what makes coffee beautiful and life-changing for so many people in the world.

What Fellow gear will you be using for competition?
I’m using two Stagg EKG kettles in my routine for water temperature control. I’ve been experimenting with different water temperatures at different times throughout the brew and the hold function really comes in handy for that purpose. This was not something I did in Nashville, so I am excited to apply it in the next round in KC.

How did you pick your competition coffee?
I chose my competition coffee because I wanted to share the bean that changed my life with the rest of the coffee community! Five years ago when Red Rooster started to really find its wings, I took part in a blind cupping and had a coffee that completely changed everything for me. I knew immediately going into this competition, that would be the coffee I’d be using. Coffee is extremely personal and so I wanted to put the two together. My journey and the coffee’s journey into one narrative.

Any advice for folks thinking about dipping their toes into the competition scene for the first time?
Just have fun and enjoy the process! Listen to yourself. Don’t overthink too much. Get plenty of rest. Learn from your mistakes. Don’t be afraid to try new methods or create new ones. Oh, and practice your open service but practice compulsory, too! It’s a big part of your score, and I think folks often spend so much time perfecting their open service we forget to practice with beans we may not be familiar with.

BLAIR SMITH | AUGIE’S COFFEE | BREWERS CUP

How did you get into the coffee industry?
I was looking for a second job after college and stumbled across an ad on Craigslist for a barista position. I had no idea that it was for a specialty shop with a full bakery. At that time, I was drinking really nasty coffee with tons of hazelnut creamer and had no idea what any drink really was: Americano, macchiato, etc. I learned a ton at this job and eventually went on to manage the cafe side for a year before moving to California and working at Augie’s Coffee. This month will be my fifth year working at Augie’s, and I have been managing my store for four and a half years.

What were your goals going into the start of the competition season?
I’ve been competing for the last four years and always trying to learn more and bring that into my routine each time. This year, I knew I wanted to focus on my water chemistry and being able to bring the same flavors I love in our warehouse to wherever the competition is held.

How have you been preparing for competition?
Prepping is essentially easier every time since I know what to expect. In the first few competitions, I’d spend many hours just figuring out how to brew coffee best and trying out different brewers. But now, I feel like I can be more intentional because I’ve had the experience to know where and how to change things quickly. The water dialing in was probably the most challenging and time-consuming such as researching and tweaking with different chemicals to achieve different attributes. It’s amazing what such small adjustments can contribute to the cup, good or bad.

How are you using Fellow gear at competition?
I’m using the Stagg [X] Dripper. I love the heat retention, and I can’t stray away from the body that it gives the coffee. I absolutely love the Stagg kettles because they are so easy to use and I like not having to hit the button to hold the temperature. I’m using two different temperatures for my routine, so it’s nice that the kettles are so efficient.

What coffee will you be using in your routine?
I’m using a relatively approachable coffee which is unique to the national competition. Usually, folks will use geishas or rare varieties from small lots. My coffee is made up of two very high yielding and rust resistant varieties and comes from a 700 kilo lot. It’s an anaerobic fermented coffee that’s been really carefully executed. It jumped off the cupping table, and it’s crazy unique. Tastes like strawberry, watermelon, plum, and cherry blossom. I’m excited to showcase a relatively inexpensive coffee that can achieve high scores through the fermentation process.

ELISABETH JOHNSON | VASHON COFFEE COMPANY | BARISTA CHAMPIONSHIPS

Elisabeth Johnson Barista Championships Competitors

Photo credit: Paige Hicks

How did you first get into coffee?
I first started working as a barista in 2010. I fell in love with cozy cafés and their well-worn sofas. As the offspring of small business owners, I loved the idea of someday owning my own café, so I decided to get a job as a barista. As I earned some years as a barista, a new wave of cafés rolled in that was much more clean and precise with more white walls and scientific research. There’s constantly something new to learn, and that’s why I’m so invested in coffee. In the beginning, I learned so many things the hard way that I was determined to learn more so that I could become an effective trainer and help new baristas have a better foundation. Now I manage a café, I’m the head of education, and I also do consulting. It’s a lot of hats to wear!

What inspired you to compete this year?
I felt like I had something to prove, and I really wanted to do better than last year. I made a lot of mistakes as a first-year competitor, and I kept telling myself, “I know I’m better than that!” I just wanted to learn from my past experiences and improve myself and my craft.

How have you been preparing for Kansas City?
I started practicing in August by participating in the USCC Preliminaries in Seattle where I placed 2nd in both Brewer’s Cup and Barista. I wasn’t sure which path to take and I wanted to try my hand at Brewer’s. After I got accepted to Glitter Cat Barista Bootcamp, it made the decision a lot clearer. I did a training workshop in Philadelphia with some coffee greats who I really admire, and it bolstered my routine a lot.

How are you using Fellow gear in your routine?
I’m using the Monty Milk Art Cortado Cups. Surprisingly, I had a very difficult time finding this size cup (4.5 oz), and it’s such a standard size for competition. I think that they are beautiful and I really wanted the judges to have a ceramic cup with a good weight to it as opposed to the simple glassware I was practicing with. A good cup makes all the difference! Not to mention, the rose gold perfectly matched the rest of my wares.

How did you pick your competition coffee?
I picked my coffee based off of a relationship with the importer, Cafe 1959, and because it was the most delicious coffee I could find. When I’m looking for a competition coffee, I go for sweetness, body, and acidity. The mouthfeel (or “tactile”) component is a huge multiplier for points in the competition, but I also wanted to choose a coffee that I personally just really enjoyed. After reaching out to one of the farmers from Finca la Julia on social media, I felt much more invested in representing this coffee because of the love and effort that goes into their art. I feel lucky that now I get to leave my mark on it!

The coffee that I’m using is a natural process Java variety from Colombia, specifically Finca la Julia in Trujillo. It’s certainly a unique coffee, and I’m excited to be able to serve it!

What’s unique about your competition routine?
I have studied this competition a lot, and I know that a thorough knowledge of the rules and what the judges are looking for is a huge component. As much as I’m focused on the points, at the end of the day, what’s important to me is that my routine feels true to who I am is a person. I hope that the work that I have put into my career and competition puts me in the top bracket of competitors vying to represent the United States at the world level. But ultimately, I’m proud of what I’ve accomplished at this time in my life, and I have a tiny cheerleader at home who already thinks I’m a winner. My daughter Scarlet is an avid supporter of me and always assures me that I’m a winner.

KIMHAK EM | PEIXOTO COFFEE ROASTERS | COFFEE IN GOOD SPIRITS

Kimhak Em Coffee In Good SpiritsTell us a little about your journey in coffee!
My journey started with my love of the cafe. I remember how much I like and still do enjoy hanging out and talking to everyone one in a coffee shop. With my professional career,  it started about three and half years ago when I started at Peixoto Coffee in Chandler, Arizona.

You’ll be combining your mixologist and barista skills at the Coffee in Good Spirits Championships. Can you tell us more about the beverages you’ll be making?
There are two rounds at Nationals. In the first round, you have to make two pairs of beverages. One of the coffee cocktails has to be hot and other has to be cold. We have to use whiskey in both of the beverages and for the coffee, one of the beverages needs espresso and the other needs to have brewed filter coffee. If you make it into the top six for the second round, everybody needs to make an Irish coffee. You are only allowed four ingredients: coffee, whiskey, cream, and sugar.

What were your goals going into the start of the competition season?
My goal is to win first place! But truthfully, my real goal is to grow as a professional and do my best. I hope I can get my stories across to the judges. I put my heart and a lot of time to this routine, it is such a fun event. I encourage anyone who is thinking about doing it to just take a leap and do it!

How are you using Fellow gear at competition?
I’m going to be using the Stagg EKG Electric Pour-Over Kettle! It helps me make sure that my water temperature is on point and heats up fast! This is so important because it will help brew my filter coffee correctly. If I don’t get the right extraction, my beverage will not taste correctly as it should.

Kimhak Em Coffee In Good Spirits ChampionshipsHow have you been preparing for competition?
I start out with just a concept in my head. I imagine how the flavors and texture would be. I used to be a cook and this practice helps me out a lot with coming up with recipes. Then, I test out the recipe in real life and adjust as I go. Next, I write out my presentation, my story. I read this out while I drive to and from work. Finally, a week before competition, I do it all together a few times until I am comfortable.

What coffee will you be using in your routine?
I’m going to be using a natural Brazil and a washed Brazil. We at Peixoto Coffee own the farm in Brazil, so I’m very proud and honored to be using our family farm coffee.

The Making of Eddy Steaming Pitcher by Fellow

Perfecting Steamed Milk: The Making of Eddy Steaming Pitcher

By | Coffee, Design

With no moving or electrical parts, one would think a steaming pitcher would be a breeze to engineer and manufacture. No complicated PID controller like Stagg EKG. No first-of-its-kind vacuum pump like Atmos. Easy, right? Right.

At least that’s what we thought when we started on this journey into steaming pitcher land. Named after the whirlpool effect in water, Eddy took two years to complete from start to finish with the design guidance from our partners at Branch. We decided against the path of least resistance and chose to swim upstream, if you will, because we knew we could make a serious statement in the saturated pitcher market if done correctly. Each of Eddy’s unique features was born from extensive user testing with baristas. Coincidentally, the features the baristas requested posed major manufacturing challenges which, after countless prototypes, we were able to conquer.

We sat down with Eddy’s product manager, Hanna McPhee, to talk about the user feedback loop, manufacturing woes, and the final product we couldn’t be more proud to share with you. The two-year process was well worth the wait.

Fellow Eddy Steaming Pitcher for latte artWhat was your role in bringing Eddy Steaming Pitcher to life?
My role centered around working with our design partners at Branch to research and prototype Eddy’s unique design features by observing specialty coffee shops and baristas. We wanted Fellow to have the best understanding of what baristas like about the current milk pitchers on the market and what they didn’t like. We then took this industry feedback and went to the drawing board to see if we could actually make a physical product that included everyone’s requests and feedback. This part was extremely tricky and the main reason it took us two years to engineer Eddy.

What inspired Fellow to dive into the espresso tool world?
Obviously, our origin is pour-over brewing equipment but we dipped our toes into drinkware with Joey. As we got into the mug game, we quickly realized we wanted to make cups that made it easier to serve milk-based drinks and pour latte art. When we started engineering this new line of drinkware called Monty Milk Art Cups, we decided to design in tandem a thoughtful steaming pitcher for creating latte art both at home and in the café. Fellow always gets very excited when brainstorming new coffee products, but we won’t make something unless we truly believe we can add our special touch to make something better than what’s currently on the market.

Eddy Steaming Pitcher pouring latte art into a Monty Milk Art Cup by FellowWhat are these differences that set Eddy apart from other pitchers?
In both form and function, Eddy is very different. From a functional perspective, the most defining feature is the sharp front crease. It’s a giant bend that goes almost all the way down the front face of the pitcher. Most steaming pitchers have this little gullet as we like to call it. It’s what you see on a pelican or some type of bird that catches fish in its beak. When pouring, the gullet creates two different flow rates which isn’t necessarily intuitive to both home baristas and professional baristas. Obviously, when you use a product for a long time, pour after pour, you get used to this change in flow rate. With Eddy, we wanted to try something different and see if we could keep the flow rate consistent from the start, which would lead to a more intuitive pour for the user. The sharp crease on Eddy did result in a faster pour because now the milk is all going at one speed. However, we do think that we accomplished creating a more intuitive drawing tool. This sharp crease combined with Eddy’s unique fluted spout, gives you more control and a better understanding of what happens with the milk when your hand moves.

From a form perspective, we worked closely with our partners at Branch to visually create something that’s unlike any other pitcher out there. We’re always trying to keep in mind designing for both specialty cafes and home kitchens. This product should be something you are proud to leave on your counter or beside your espresso machine and not something you want to hide away in your cupboard.

What was your user testing process?
We created many different prototypes and had several cafés around the Bay Area use the product in the café behind bar. This was really important because wanted them to use Eddy in the same workflow they would during normal service hours. After every new production round, we’d bring the new, more polished version of Eddy back to our test cafés and start the process all over again. In addition to café use, we interviewed many different barista champ competitors via Skype and also had them send pictures of how they hold their current steaming pitchers. I have a file on my desktop with dozens of close-up photos of people’s hands holding different pitchers. It’s a little creepy to be honest.

How did Eddy’s design morph after giving the different prototypes to baristas?
Every feature of Eddy was impacted by user testing but the ribbon handle, measurement aids, and stainless steel thickness stand out the most in my mind. We kept hearing over and over again that milk waste was a really big concern for small specialty cafés. To help mitigate waste, we added measurement aids inside of Eddy to ensure precise milk pours. We also got feedback from a bunch of different baristas about the importance of thickness for a steaming pitcher. They wanted to be able to easily gauge how hot the milk was inside of the pitcher. These conversations directly impacted Eddy’s thickness. Lastly, and probably most importantly, our user testing lead us to our ribbon handle. When we first started making this pitcher, our goal was to make the end all, be all handle. This was going to be the best handle that you could ever dream of. What we quickly realized is that how baristas hold a steaming pitcher is pretty personal. It’s like how you hold a pencil or paintbrush. So instead of taking a hard stance on the perfect handle, we did a complete 180 and switched our stance to making a universal handle that would be flexible for all pouring styles. With the open-ended ribbon handle, Eddy can be manipulated and held anyway the barista chooses.

Eddy Steaming Pitcher Ribbon HandleAny hiccups during the design process?
So it turns out that when metal is cylindrical, it doesn’t like to bend into a sharp crease. It took many, many versions of the product samples to be able to have front crease without the pitcher literally splitting in half.  This becomes even harder to do when you are trying to make thousands of consistent creases.

It was also a challenge to figure out a way to make the ribbon handle as consistent as possible, as we wanted the handle distance from the body to be a very specific measurement based on feedback from users.

Do you think Eddy will be showing up in a barista champs competition near you?
Definitely. I think the fun part about latte art and milk-based drinks is that baristas are always coming up with incredible new techniques and cool new ways to perfect the process. Eddy is another tool to help push the boundaries on what baristas can do. Really, at the end of the day, it’s about having fun and taking pride in your coffee craft and Eddy helps support that.


Eddy Steaming Pitcher is available in graphite and polished steel and in 12 oz and 18 oz sizes. Grab one for your collection!

The Golden Ratio For Brewing Coffee

By | Coffee
Ahh yes, the Golden Ratio. The perfect balance between coffee and water for brewing that perfect cup.

One of the biggest barriers to entry we hear when talking to home brewing beginners is knowing the right coffee-to-water ratio. Especially if you’re leaving the world of Keurig (bless your soul) or trying to cut back on purchasing your daily cup of coffee, learning a new brew method and experimenting with the right recipe seems daunting – and even a waste of good coffee. So let’s break down everything you need to know for the perfect coffee-to-water brew ratio.

Monty Milk Art Cup for latte art by Fellow

Picasso Your Pour: Why Parabolic Slopes Are Better For Latte Art

By | Coffee, Design

A cousin to our Joey Mug, Monty Milk Art Cup is our newest double-wall ceramic drinkware. While Monty can absolutely be home to brewed coffee—our [X] and [XF] Drippers fit perfectly on top of the latte and cappuccino sizes—the design features were specifically engineered for pouring beautiful espresso drinks. So what’s Monty’s secret? A hidden parabolic slope which helps you Picasso your pour by lifting crema to the top without disruption.

First, let’s breakdown the difference between a parabolic slope and a non-parabolic slope. Think back to your algebra days. The slope that’s hidden inside of Monty is similar to the graph created by a quadratic function. The U shape is a welcoming, gentle home for your freshly frothed milk. A cup or a mug with a non-parabolic slope often has sharp 90° or 45° angles. The care put into your milk is instantly mitigated by the hard bottom.

Parabolic slope vs non parabolic slope for pouring latte artNow, let’s talk about the pour. Good latte art has strong definition with bright white milk and dark brown crema. Not so good latte art is often described by baristas as “blown out” because the white and brown mix together to form a lazy tan. To achieve this necessary definition, crema needs to be to lifted to the surface fully intact. This provides a solid canvas to draw on with your milk. The key to getting great contrast is steering clear of turbulence. If you’re pouring milk into a squared, non-parabolic bottom, the milk will inevitably crash into a wall or corner creating turbulence and disrupting the crema. However, if you’re pouring milk into Monty’s parabolic slope, the rounded bottom helps maintain surface tension until you are ready to break it up and start the lines for that beautiful inverted swan with a triple tulip head that everyone loves so much.

Apart from the parabolic slope, our product team kept cafés and baristas top of mind throughout the entire design process. The sizes—latte, cappuccino, cortado, and demitasse—were chosen specifically for espresso-based drinks. We also specifically designed these cups to be square on the outside for convenient stacking in cafés or on an espresso machine. The latte size stacks with the cappuccino size while the cortado stacks with the demitasse. Also, unlike our Joey mug, Monty is dishwasher safe.

We think these kinds of coffees and roasts are amazing—but it’s not the style of coffee we really love drinking every morning, black.

For that reason, we let Limu Kosa cook a little longer in the roaster, allowing its natural sugars to develop and caramelize. The result is a bean that carries that smooth chocolatey body we love about coffee, with super tasty expressive notes on top. As your cup of Limu cools, notice how the flavors develop over 20 minutes!

Barista Hustle x Fellow | A New Partnership

By | Coffee

If you made it this far, then you must have seen a social media post announcing a Barista Hustle and Fellow partnership. What? Huh? We’re here to explain.

Fellow is now at the helm of Barista Hustle Tools, an offshoot of Matt Perger’s Barista Hustle brand. Fellow is not Barista Hustle nor is Barista Hustle Fellow. Fellow is now leading the charge of Barista Hustle Tools, or BHT, as we’ll often refer to it by. Still confused? Stick with us for a few more paragraphs.

Barista Hustle has been a strong voice in the coffee industry since its launch in 2015 by world champion brewer Matt Perger. Starting first as an education platform, Matt quickly realized great tools were missing from his teaching arsenal. Barista Hustle proceeded to launch three coffee tools that could stand up to the rigor of professional use and elevate technical precision without unnecessary complexity.

Barista Hustle x Fellow Partnership

As of today, the reigns of Barista Hustle’s product line has been handed over to Fellow under the name of Barista Hustle Tools. Where Barista Hustle is the brainchild of a coffee prodigy, Fellow is the brainchild of a product design fanatic. This partnership will enable Barista Hustle Tools to produce even more durable, precise, and fairly priced tools for baristas, coffee professionals, and enthusiasts around the world.

“We reached out to Fellow to expand the line of our tools because their knowledge of product design and manufacturing is first class,” said Matt Perger. “One of my goals with Barista Hustle has always been to solve barista pain points and expand accessibility. I’m confident Fellow, under the Barista Hustle Tools name, has the know-how and talent to make this happen.”

While Matt and Barista Hustle will still be heavily involved from the ideation side, Fellow is taking over engineering, manufacturing, distribution, and sales. The current product offerings– the BH Tamper, BH Pitcher, and BH Cupping Bowls –are now available to purchase from the just-launched Barista Hustle Tools website (BaristaHustleTools.com), as well as through Fellow’s wholesale team and San Francisco retail store.

“We’re excited to work with Matt on a regular basis to collaborate and push on new product ideas. His depth of coffee knowledge is staggering,” said Jake Miller, Fellow’s founder. “2019 is set to be a big year for new products under the Barista Hustle Tools name.”

Barista Hustle Tools x Fellow Product Line

How will this impact the flow at Fellow? A short but honest answer…it won’t. Business as usual will proceed on the Fellow side of things, and all Barista Hustle Tools news will take place over on Barista Hustle’s Instagram feed. Fellow production and distribution timelines will not impact Barista Hustle Tools’ production and distribution and vice versa. If you have any remaining questions, please send us a note at hello@fellowproducts.com.

We couldn’t be more excited to take over the ship of Barista Hustle Tools’ today while continuing to work with Matt and the BH team on developing innovative products for 2019. Head to the sparkling new website to see the current offering of gear!

How Vacuums Prevent Coffee Staleness

How Vacuums Prevent Coffee Staling

By | Coffee

Coffee storage and freshness are influenced by a confusing mix of variables that greatly affect how long your beans stay tasty. We’re a big fan of vacuums as a means of extending your coffee’s shelf life (if you couldn’t tell from our new Atmos Vacuum Canister). Here’s a handy guide on coffee freshness that explains why vacuum canisters are so effective at keeping your coffee fresher, longer.

Why is oxygen so bad for coffee beans?
Oxygen is bad for coffee, snacks, or pretty much any perishable item because it makes things stale through a process called oxidation. To set the stage, we define “staleness” as the loss of desirable flavors and aroma, and/or the creation of undesirable flavors and aroma. When oxygen comes in contact with a molecule, it removes an electron from the molecule. This is called oxidation. The molecule that loses an electron becomes unstable and reactive, which then results in the loss of flavor or creation of an undesirable flavor.

For coffee beans, oxygen negatively affects VOCs (volatile organic compounds). VOCs are chemical byproducts of roasting that evaporate quickly. They are generally considered good because they contribute to aroma.³ When oxygen comes in contact with VOCs, they become unstable and result in coffee losing its aroma.

Oxygen also affects lipids, which are the coffee oils in the bean. Oxidation turns lipids into peroxide which contributes to rancid taste notes.7

Fellow Atmos Vacuum Canister for Coffee
What’s a vacuum container and how does it help with oxidation?
First off, let’s define what a vacuum is. A vacuum is a closed system in which pressure is less than atmospheric. In order for this to happen, you need a constant amount of space (i.e. a rigid container) where air particles are removed.

There’s a lot of airtight containers/bags out there that get rid of some air, but these aren’t necessarily a true vacuum. An easy way to tell if you don’t have a vacuum container is if your container shrinks (i.e. is it a bag or does it have a lid that collapses into the container). If your container shrinks, it is not a vacuum and will not decrease the pressure below atmospheric.

But why is pressure so important?
Oxidation speed (the rate of oxidation) depends on pressure.¹A reaction occurs when two molecules collide. If there are more molecules in a smaller area, the chances of collision increases and the reaction happens faster.

Air is a mixture of nitrogen, CO2, and oxygen. For the oxidation reaction, we care only about the pressure of oxygen – or the partial pressure. The partial pressure of oxygen is the fraction of oxygen in the air, times the total pressure of the air. The partial pressure of oxygen can be changed by changing the fraction of oxygen in air (i.e. nitrogen flushing) or changing the total pressure of the air (i.e. vacuum chamber).

Fraction of Oxygen in Air x Total Pressure Air = Partial Pressure of Oxygen

Here’s an example of this equation for calculating the partial pressure of oxygen:

—————-

What is the partial pressure of oxygen in a) atmosphere and b) a half vacuum?

Fraction of O2 in air = .2095

Total pressure of atmospheric air = 101.325kPa

Total pressure in half vacuum air = 50.66 kPa

Fraction O2 x Total Pressure = O2 partial pressure

.2095 O2 x 101.325 kPa = 21.23 kPa

.2095 O2 x 50.66 kPa = 10.61 kPa

Therefore, O2 partial pressure a) 21.23 kPa and b) 10.61kPa  

——————–

From calculating the partial pressure of oxygen in a half vacuum, we can conclude the oxidation rate at full pressure is twice as fast as the oxidation rate at half pressure, which is the environment Atmos creates. Although oxidation and freshness have a very strong correlation, because there are other factors at play like degassing, the relationship is not linear. If it was, we could say Atmos slows the oxidation rate by 2x, and therefore extends coffee’s shelf life by 100%.

We landed on the conclusion that Atmos extends coffee’s shelf life up to 50% due to the many variables that go into how fast a specific bean goes stale (origin, roast, how many times you open your canister, degassing, etc.)

What happens to the degassing rate of coffee in a vacuum?
If vacuum chambers affect gas on the molecular level, then it’s important to consider how vacuums affect coffee degassing. When coffee is roasted, gases form inside the bean. After roasting, gases (mostly carbon dioxide) start seeping out. When coffee is a few days old and very fresh, a bulk of the carbon dioxide formed leaves your beans. Because vacuums create a pressure gradient, CO2 degassing will occur quicker than at full atmospheric pressure. When we first started designing a vacuum canister, we wanted to make sure this didn’t harm the flavor profile of coffee or its ability to stay fresher longer.

Our conclusion was twofold. First, 40% of CO2 in coffee escapes within the first 24 hours. Most of the degassing happens very quickly in the first few days after roasting.² By the time you get your coffee, it has probably already done a bulk of its degassing so vacuum canister effects on CO2 are minimal.

If you do get your coffee extremely fresh (1-3 days off roast), a vacuum canister will degas coffee quicker, which in theory, is a negative outcome because degassing too quickly can also lead to the loss of volatile organic compounds (VOCs) that create aroma. However, as we talked about earlier, it turns out those same VOCs, along with lipids, are the molecules most affected by oxidation. Oxidation is the primary reason for coffee staling.5 When assessing the impact of fast degassing versus oxidation, it is clear oxidation has such an overwhelming impact on coffee’s flavor that protecting your beans from oxidation is significantly more impactful than preventing a small increase in the degassing rate.

Since this is a sealed environment, will this mean there is a buildup of CO2?
We’ve received a few questions about CO2 buildup in Atmos compared to in a bag with a standard one-way valve. Commercial coffee bean bags with CO2 degassing valves are designed to relieve CO2 pressure buildup and prevent bag rupture, not to necessarily keep coffee fresher for longer. In a vacuum chamber, the pressure is low enough that CO2 buildup is not a concern. CO2 in the air around the beans is non-reactive and will not affect the flavor of the coffee. CO2 does, however, affect your coffee’s flavor once you start brewing, so make sure to bloom your bed of grounds before brewing!4

Can I put Atmos in the freezer to store coffee?

You can freeze Atmos but it’s not the best use of the product. Since coffee beans should be frozen in individual servings as to not refreeze and freeze beans continuously, Atmos doesn’t make the most sense. Atmos is intended to hold multiple servings, so it would be a waste of space in your freezer to put only one serving of beans inside. Placing Atmos in the freezer will also eventually reduce the life-span of the vacuum seal.

Fellow Atmos Vacuum Canister for Coffee

A Q&A with the Inventor of Atmos Vacuum Canister

By | Coffee, Design

Fellow’s latest product, Atmos Vacuum Canister, launched in September with the important mission to keep coffee fresher for longer. The minimalist canister looks simple, but the science and engineering inside is no joke. Drew Cosgarea, Fellow’s Product Development Engineer, invented Atmos during his junior year of college at Stanford and spent the next four years working hard to bringing it to market. To celebrate our newest engineer on the Fellow team, we had Drew dig up old photos from his college days and then sit in the hot seat to answer all things Atmos and dive deeper into what’s exactly happening inside the most effective coffee canister out there.

What’s the origin story of Atmos?
During the last quarter of my junior year (spring of 2014), I was in a class called ME203 at Stanford. This is a popular design and manufacturing class where you have ten weeks to come up with a physical product idea, make multiple prototypes, and then present a “finished” version at the end of the quarter.

And how did you land on coffee storage?
My class project corresponded to a time where I had just recently started drinking coffee. I’d buy a bag on the weekend and use it all week, but by Friday, the bag tasted off. I realized that a good product could be something to keep my bag of coffee fresher for longer.

What was the first prototype like?
I made the first version of Atmos in that class, except that it had a hand pump. At the end of the class, we presented at an expo in the d.school where about a couple hundred people came and looked at all the products. Someone came up to my table and said he’d actually use this but didn’t like the separate pump. So I went to the professor of the class, David Beach, and told him I can make the vacuum canister a lot better. I asked him if he’d be willing to mentor me to turn Atmos into a real product.

He said it would be a really hard thing to do, but if I committed the time, we can do an independent study the fall of my senior year. I knew I wanted to put a pump into the lid and power it with a twisting motion, which as far as I know, has never been done before. During the study, we iterated through a series of prototypes starting with literally just cutting components of a fish tank pump. But by the end of the independent study, we had a functional, machined proof of concept. No fish tank pumps required!

Atmos Vacuum Canister Drew Cosgarea

Atmos Vacuum Canister by FellowWhat happened after graduation?
Well, I moved to Arizona for a year to train full time for the 2016 Olympic Swimming Trials. I got extremely bored during that time, so I continued working on the project while training. I worked on the CAD and eventually raised $25,000 from a couple different investors, basically friends and family, to help me get the patent on this. I eventually got the patent for a vacuum sealable container with an internal pump mechanism. This is the only internal curved vacuum pump. There were no designs for curved pumps that could be integrated into a lid.

Where does Fellow come into this whole story?
So by now, it’s 2017 and Atmos had been an idea of mine for three years. I spent the last of the money on the patent application, and I was running out of steam. I was about ready to give up on the project when I had a conversation with Professor Perry Klebahn from Stanford. He encouraged me to not walk away, but instead, chat with Jake at Fellow who was in his launchpad class in the d.school a few years back. So I headed to Fellow’s old office in the Dogpatch and met with Jake for the first time. Coincidentally, Fellow had been wanting to make a coffee storage vehicle for the past few years and Jake was excited to add my technology to Fellow’s portfolio of products.

How did Fellow help bring Atmos to market?
Fellow officially took on the Atmos project January of 2018. A side note, I had always referred to this product as Hypo (comes from “hypobaric” which means low pressure and the name Atmos didn’t come along until July of this year). The final naming process took about a month, but I’m so glad it ended up the way it did. Anyways, Fellow and Branch Creative worked for months to create the beautiful design ID and iron out kinks. Then in June, I actually joined the Fellow team officially. This was not the intention when I passed off Atmos, but something kept drawing me back to Fellow and I was excited to design new products with them.

My first day at Fellow was a flight to Taiwan for factory visits. I got to see the mold tooling for the curved pumped piece. This curved pump is the foundation of my invention and a huge headache, so it was pretty rad to see this in real life. Ever since getting back from the trip, I’ve been improving on the design and guiding production ramp up through launch at the end of September.

Why is Atmos better than what’s on the market currently?
At the time of invention, there were no vacuum canisters that didn’t require an extra pump. There are also some other non-vacuum coffee containers out there, but they’re total gimmicks. Here’s why. When you roast coffee, a bunch of compounds form that make it smell and taste good. Oxygen comes in and steals electrons from these compounds, which makes them smell and taste bad. This is called an oxidation, and it’s the reason coffee goes stale. How quickly oxidation happens depends on the pressure of the oxygen. Again, pressure. It’s a fundamental principle of chemistry. If you’re not storing in a vacuum, you’re not slowing oxidation. Frankly, non-vacuum containers are no different than leaving your beans in the coffee bag and folding the tabs down. Not to mention, Atmos is beautifully designed and minimalist. The whole idea is you can’t tell there’s a pump inside.

Fellow Atmos Vacuum CanisterDid you have any big hiccups while making Atmos?
I would say there were at least four times that I wanted to totally ditch the project. There were times when the only thing that kept me going was knowing that I borrowed money from my friends and family. I didn’t want to let them down.

How do you feel now that your baby is finally out in the world?
It’s super satisfying. To be able to see the entire process from the original idea to the industrial design to the marketing campaign to fulfillment, it’s pretty magical. I never imagined it was actually possible.

How many Atmos’ did your mom buy on launch day?
Sheila Cosgarea bought six. A set of the clear glass and a set of the matte black stainless steel.

What are you going to store in Atmos?
I’m definitely going to put full bags of coffee in the 1.2 liter glass size. I like to see the label and remember the tasting notes that I’m drinking. Also, specialty bags are so well designed, why would you cover them? Also, when you put a bag of coffee inside, the bag also gets vacuumed sealed!

What’s next in your product inventing pipeline?
From Atmos’ idea conception until the product shipped, it took me four years. I would say now, my goal is to cut that down to eight months for the next Fellow product. That’s why I’m here. They have the resources and mentorship to learn how to do this along with an incredible brand that I’m excited to design for. (Note: We did not pay him to say this. Although, he is on our payroll…)
