AeroPress is a device for making coffee or filtering liquids in general. It was developed in 2005 by Aerobie President Alan Adler. Coffee mixed in hot water is forced through a paper or metal sieve after 10 to 60 seconds of extraction (depending on the strength of the coffee we want to achieve). Medium coffee grinding roughness is used for Aeropress preparation.  The device consists of 2 plastic cylinders. One is terminated by a rubber plunger that fits exactly into a larger cylinder and can create pressure in it, similar to a syringe.
