Pre-heating the carafe, wrapping a dish towel around it, spending weeks knitting a special French press cozy following a pattern that you later realize was for an infinity scarf… these are all techniques people use to ensure that their coffee stays warm during the immersion brewing process.
Enter Clara: Fellow’s uniquely designed French press with double-vacuum insulated walls to keep your coffee hot while it brews, and for hours after. Why is this important? Here’s what we know about the optimal brewing temperature for French press.
The Golden Range
The Specialty Coffee Association (and us) recommends brewing coffee between 195°F and 205°F. However, many French press recipes suggest using boiling water or water just off the boil. This is because the traditional glass French press starts losing heat almost immediately and then you’re going to let it sit for four minutes (or if you’re James Hoffman, add another five).
Get In On The Extraction
With Clara, you can use the exact temperature for optimal brewing without worrying about heat loss, thanks to the insulated walls. Water temperature controls the extraction of your coffee: hotter water extracts faster, colder water extracts slower. If your water is too hot, your coffee may taste bitter. If your water is too cold, the results may taste sour and weak. By sustaining a consistent temperature throughout the steeping, Clara allows for a more even extraction than traditional French presses, resulting in a perfectly balanced cup.
Dial It In Per Roast
It’s generally recommended that you tweak the temperature of your water depending on what level of roast you’re using. When brewing with darker roasts, you can use water in the 180°F-190°F range to avoid over-extracting, while with lighter roasts you don’t have to worry about this and can use water in the 206°F-208°F range. Rather than overshooting these ranges to account for heat-loss, with Clara you can use water heated to the exact temperature to suit your coffee, and trust it’s going to stay that way throughout the brewing process.

Flash Forward To Two Hours Later…
…and you’re back for another cup. Another feature of Clara’s insulated walls is that they keep your coffee warm for hours, so your second and third cup taste just as good as the first.
Clara’s innovative design was recognized by the Specialty Coffee Association. It was named Best New Product in the Consumer Coffee Preparation & Serving (Non-Electric) category for 2022!
