The Aerobie AeroPress is a revolutionary new method for making perfect coffee anytime. It is so easy to use that once you own an AeroPress, you won't want to use instant coffee or more expensive coffee machines. The AeroPress uses gentle air pressure to create a smooth, acidic flavor without bitterness. Other coffee machines drip hot water over a bed of ground coffee, leading to excessive extraction in the middle and flavor extraction at the edges. However, the AeroPress brewing system ensures even extraction for the ultimate coffee taste. The AeroPress comes with a complete user manual. Just add your coffee and water.
