The Aeropress is an immersion style coffee maker. Medium-fine ground coffee is immersed in the chamber with a short brew time. The pressure produced when pushing the plunger through the chamber extracts the delicious flavour of your coffee. Coffee through an Aeropress will also be free of grit as it passes through a paper micro-filter. Using your AeroPress coffee maker is simple, fun and probably the fastest was to brew perfectly delicious coffee.
