When brewing coffee with an AeroPress, you use very hot but not boiling water, you use finely ground coffee, and the filter prevents any grit from getting into your cup, all of which are additional important reasons AeroPress brewed coffee is so remarkably delicious.
To brew a double espresso or 10-ounce cup of coffee:
- Place a microfilter in the bottom cap of the AeroPress chamber and twist the cap tightly closed.
- Place two scoops of ground coffee from the included AeroPress scoop into the chamber.
- Stand the chamber on a sturdy mug, then proceed to pour hot water into the top of the chamber (175 degrees F is optimal).
- Stir the water and coffee with the included paddle for about 10 seconds.
- Insert the plunger into the chamber and gently press down about a quarter of an inch and continue to maintain that pressure for 20 to 30 seconds (gentle pressure is the key to easy AeroPressing).
The AeroPress is the result of several years of applied research by inventor/engineer Alan Adler, who conducted numerous brewing experiments, measuring the brew with laboratory instruments. The experiments demonstrated that proper temperature, total immersion and rapid filtering were key to flavor excellence. He then designed and tested dozens of brewers before settling on the AeroPress design. Adler's best-known invention is the Aerobie flying ring which set the Guinness World record for the world's farthest throw (1,333 feet).
