For the record, here's my recipe for making coffee with an Aeropress using the inverted method.
- Set up Aeropress upside down. The plunger should be set at approximately (number of cups + 1), to leave a bit of working room.
- Place a filter inside the cap. Leave the cap aside.
- Add coffee into the chamber. Use approximately 14 g (= 1 Aeropress scoop or 2 plunger scoops) of fine-medium grind coffee per cup
- Add water (90 °C - not boiling) water slowly , so that coffee does not burn. The amount of water for each cup is a little over the distance between two marks on the chamber. For example, for 1 cup with the plunger set at the middle of , fill to a little over .
- Stir with paddle to mix and remove lumps. Twist the cap onto the chamber.
- Brew for 1-2 minutes.
- Put cup or jug on top of cap and invert quickly.
- Press plunger with steady force. The chamber will hiss as air is released. Continue pushing until hissing stops. This will take about 10 seconds for a single cup, longer for more cups. Hopefully there should be a very small amount of crema in the cup.
