The AeroPress is a popular coffee brewing device that uses air pressure to extract flavors from coffee grounds. It consists of a cylindrical chamber, a plunger, and a filter cap. Users add coffee and hot water to the chamber, then press the plunger down to force the water through the grounds and filter, resulting in a concentrated coffee. This method is known for its versatility, allowing users to adjust brewing time and coffee-to-water ratios. The AeroPress is lightweight and portable, making it ideal for travel or outdoor use. It has gained a following among coffee enthusiasts for its ability to produce a rich, smooth cup of coffee.
