AeroPress
The AeroPress is a manual coffeemaker invented by Alan Adler, founder of AeroPress, Inc. (formerly Aerobie Inc.). It consists of a cylindrical brewing chamber, a plunger with an airtight silicone seal, and a screw-on cap which holds a paper or mesh filter. Coffee is steeped inside, then forced through the filter by pressing the plunger down through the chamber.
The use of pressure makes it capable of brewing highly concentrated coffee, comparable to espresso, but it can also be used to brew filter-strength coffee and cold brew.
The brewer consists of a translucent cylindrical chamber, and a plunger with an airtight silicone seal, similar to a syringe. A filter cap is screwed onto the end of the chamber, to hold a small round paper filter in place.
The chamber and plunger are made of translucent plastic. Early AeroPress models used clear polycarbonate, but in 2009 switched to BPA-free copolyester, then in 2014 to polypropylene. According to the company, lab tests found that the original model did not leach BPA into brewed coffee. The lettering changed color several times and the plastic changed from clear to gray, but the brewer's design was otherwise unchanged between these versions. In 2023, the company released new clear models made of Tritan.
The base model AeroPress includes a scoop for ground coffee, a stirring paddle, and a pack of paper filters. Earlier units also included a carrying bag, a plastic holder for the filters, and a funnel for loading coffee and pressing into smaller vessels, but as of 2024 these are sold separately. XL models includes the scoop, paddle, filters, and a 20oz plastic carafe.
AeroPress units ship with a pack of 350 circular paper filters. In 2017, the manufacturer recommended against using metal mesh filters, claiming that paper filters improved taste. In contrast, some immersion brewers, such as the French press, are used almost exclusively with metal filters. As of 2024, AeroPress sells their own stainless steel mesh filter.
The AeroPress was invented by retired Stanford engineering lecturer Alan Adler, who had previously patented and sold the Aerobie flying ring in the 1980s. Adler began prototyping the AeroPress in his garage in 2004, with the intention of reducing acidity and bitterness in his daily cup of coffee. He expressed dissatisfaction with espresso machines, pour-over, and the french press, and wanted greater control over parameters such as brew time, water temperature, and grind size.
Adler sold the AeroPress through his existing company, Aerobie Inc.. In 2017, Spin Master purchased the rights to the Aerobie, and the company was renamed to AeroPress, Inc.
