Here’s my suggestion of how to make a standard cup of AeroPress coffee using the inverted method, in which the plunger is on the bottom of the AeroPress tube.
Step One
Bring 350 grams or so of water to a boil. Weigh out 15–18 grams of coffee (I suggest 17-18). Grind beans to a medium-fine texture, slightly finer than sea salt.
Step two
Place a paper Aeropress filter in the Aeropress lid. Use some of the heated water to wet the filter to create a seal and preheat your lid.
Step three
Assemble your Aeropress. Push the plunger into the tube about half an inch to form a stable base for the coffee and water to be poured into.
Step four
Place the AeroPress on the scale with the flared end up (upside-down), then tare the weight.
Step five
Using the funnel, pour the ground coffee into the AeroPress. Be careful not to spill any grounds into the ring-shaped gutter at the top, because that will affect the seal.
Step six
Start timer and begin lightly pouring 35 grams of water (178-200F) onto the grounds. Make sure all the grounds have been dampened and let sit for 30 seconds.
Step seven
Fill the rest of the AeroPress with another 210 grams of water. Let sit for 1 minute. Stir grounds 10 times to agitate grounds for a more even extraction.
Step eight
Fill the rest of the AeroPress with another 210 grams of water. Let sit for 1 minute. Stir grounds 10 times to agitate grounds for a more even extraction.
Step nine
Fasten the cap tightly. Flip the AeroPress over quickly and place it on the cup. Begin slowly applying downward pressure. There should be about 30 pounds of pressure. If the pushing feels too easy, your grind is likely too coarse or something isn’t sealed correctly. If it’s very hard to push, your grounds were too fine. Stop once you hear the hiss of air.
Step ten
Fasten the cap tightly. Flip the AeroPress over quickly and place it on the cup. Begin slowly applying downward pressure. There should be about 30 pounds of pressure. If the pushing feels too easy, your grind is likely too coarse or something isn’t sealed correctly. If it’s very hard to push, your grounds were too fine. Stop once you hear the hiss of air.
Step eleven
Remove the AeroPress from the coffee cup. Place cup on scale and tare. Pour in an additional 30-60 grams of water (to taste or preference. I suggest 55g).
Step twelve
Over a trash can, remove the AeroPress lid and push the plunger the remaining inch to removing the coffee puck and to relieve pressure off of the rubber.
Step thirteen
Enjoy your cup of AeroPress coffee!
