FLASK French Press | How-to Brew

If you’ve decided to make brewing in the FLASK your new morning ritual, here is a quick how-to to maximize your experience!

Step 1. Disassemble your FLASK – remove the inner brewing chamber from the glass carafe, the press assembly from the brewing chamber, and unscrew the bottom screen from the brewing chamber:

Step 2. (Optional) Place a FLASK paper filter into the top of the screen. Brewing without a paper filter is just as enjoyable. Including a filter will result in a more refined and smoother-tasting brew, however.Flask French Press Brewing step 5 - insert paper filter

Step 3. Re-attach the screen to the bottom of the brewing chamber. Add ground coffee (or loose-leaf tea) to the brewing chamber. Grind size will vary based on your preference and can vary in any size from coarse to drip. However, smaller (espresso) grinds will create more resistance when plunging. If your grinder has a scale of 1-10, we recommend trying a grind setting of 6-7.

The FLASK will brew approximately 17 fl.oz. of coffee, and the amount of coffee you add will depend on how strong you prefer your brew. The included scoop holds approximately 2 tbsp, so using 2 scoops provides ~4 tbsp of coffee. We recommend approximately 2 rounded tablespoons of coffee per 8 fl.oz. of water. Add more if you would like to allow for dilution later. Re-insert the brewing chamber into the glass carafe.

Step 7. To clean the FLASK, simply remove the brewing chamber from the glass carafe, unscrew the bottom screen from the brewing chamber, then push the spent grounds or tea leaves out into your compost bucket or waste bin. Use a bottle brush (not included) to gently clean the inside of the brewing chamber and carafe. The screen portion can be further disassembled for thorough cleaning.
