Aeropress

Step 1

Bring 7 oz (200 g) of water to a boil. Weigh out 15–18 grams of coffee (depending on your preferred strength). Grind to a texture slightly finer than sea salt.

Step 2

Insert a paper filter into the Aeropress 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 the filter can absorb it.

Step 4

Assemble your AeroPress. Make sure the entire assembly is dry, since any residual moisture can compromise the device’s seal.

Step 5

Place it on your scale with the flared end up, and 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 6

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

Step 7

Start a timer. Add twice the weight of water than you have grounds (e.g., for 15 grams coffee, add 30 grams water). The water should be about 200 degrees F.

Step 8

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 9

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

Step 10

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