The Aerobie AeroPress is a revolutionary new method for brewing 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 makers drip hot water over a bed of ground coffee, leading to excessive extraction in the middle and aroma extraction at the edges. However, the AeroPress brewing system ensures even extraction for the ultimate coffee flavor. The AeroPress comes with a complete user manual. Just add your coffee and water.
