Aeropress Brew Guide

After searching far and wide we have settled on Blue Bottle Coffee’s brew method as the definitive go-to guide for the perfect Aeropress. We have re-published their guide here with a few tweaks and changes.

Step 1
Bring 200 g of water to a boil. Weigh 18 grams of coffee ground to a texture slightly finer than sea salt.

Step 2
Insert a paper filter into the AeroPress’s detachable plastic cap.

Step 3
Use some of your hot water to wet your filter and cap. The water serves a dual function here: It helps the filter adhere to the cap, and heats your brewing vessel. This can be challenging as the water is hot and the cap is quite small: Hold the cap by its “ears” and pour the water very slowly so it can be absorbed by the filter.

Step 4
Place it on your scale with the flared end up, then tare the weight. The numbers should appear upside-down. It’s possible to attach the black filter cap and place it right side-up, but this tends to cause leakage and make accurate brewing difficult.

Step 5
Add your ground coffee. Be careful not to spill any grounds into the ring-shaped gutter at the top of the AeroPress.

Step 6
Start a timer. Add twice the weight of water than you have grounds (e.g., for 18 grams coffee, add 36 grams water). The water should be about 200 degrees F.

Step 7
Make sure the coffee is saturated evenly, tamping slightly with the paddle or butter knife if necessary, and let it sit for 30 seconds.

Step 8
Use the remainder of the hot water to fill the chamber.

Step 9
After a minute has elapsed, stir grounds 10 times to agitate.

Step 10
Fasten the cap, ensuring it locks into the grooves tightly. Flip the whole assembly over with haste and control. Position it atop your brew vessel and begin applying downward pressure. You will experience about 30 pounds of resistance here. If the pushing feels too easy, your grind is likely too coarse; if it’s very hard to push, chances are the grind is too fine. Your coffee is fully brewed once it begins to make a hissing sound. This means there is no more water to push through the device. Do not push after you hear this hissing sound or your coffee will be too bitter.

Step 11
Once you’ve unscrewed the cap, you can pop out the filter and the puck of condensed grounds by simply pushing AeroPress’s interior section a final centimeter.
