AeroPress

The AeroPress is a manual coffeemaker invented by Alan Adler, founder of AeroPress, Inc. (formerly Aerobie Inc.). It consists of a cylindrical brewing chamber, a plunger with an airtight silicone seal, and a screw-on cap which holds a paper or mesh filter. Coffee is steeped inside, then forced through the filter by pressing the plunger down through the chamber.

The use of pressure makes it capable of brewing highly concentrated coffee, comparable to espresso, but it can also be used to brew filter-strength coffee and cold brew.
