The AeroPress is a manual coffeemaker invented by Alan Adler, founder of AeroPress, Inc., formerly Aerobie, Inc. It consists of a cylindrical chamber, and a plunger with an airtight silicone seal, similar to a syringe. Ground coffee beans and water are steeped inside, then forced through a filter by pressing the plunger through the chamber. It is capable of brewing highly concentrated coffee, which the manufacturer describes as "espresso style", but can also be used to brew filter strength coffee, or cold brew coffee.[1]

History[edit]

The AeroPress was invented by retired Stanford engineering lecturer Alan Adler, who had previously founded the company Aerobie, Inc. to sell the Aerobie flying ring.[2]

In 2005, Adler designed the AeroPress hoping to improve his daily coffee by using pressure to decrease brew time and reduce bitterness.[3] It gained a cult following among coffee enthusiasts.[4][5][6]

In 2017, Aerobie, Inc. sold the rights to the Aerobie toy to Spin Master, and changed its name to AeroPress, Inc.[2]

In 2019, AeroPress, Inc. announced the AeroPress Go, a travel-sized model with a reduced chamber capacity, smaller accessories, and an included travel cup.

World AeroPress Championship[edit]

The World AeroPress Championship is an international fan-led AeroPress brewing competition. It began in Oslo, Norway in 2008,[7] and continued yearly. The 2020 championship was cancelled due to the COVID-19 pandemic.[8]

Materials[edit]

The chamber and plunger are moulded out of translucent plastic, tinted a grey colour. The original AeroPress models used polycarbonate, but in 2009 switched to BPA-free copolyester, then in 2014 to polypropylene.[9] The company claims that in lab testing, no BPA leached from these early models into brewed coffee.[9] The lettering changed color several times, but the brewer's design was otherwise unchanged between these versions.

Methods of brewing[edit]

Traditional[edit]

Brewing a pot of coffee with the Aeropress
Fresh coffee produced from the Aeropress

According to the instructions, fine-ground coffee is placed in the bottom of the larger cylinder on top of a paper microfilter. Hot water at approximately 79 or 85 °C (175 or 185 °F)[10] is then poured over the coffee; this mixture is stirred for approximately 10 seconds before being forced through the microfilter by pushing the plunger downwards.[11] In the different coffee competitions worldwide (World Barista Championship, Brewers Cup), the coffee is more often ground slightly finer than 'filter grind', and the dose is between 14 and 20 g (0.49 and 0.71 oz), with about 200 to 230 ml (7.0 to 8.1 imp fl oz; 6.8 to 7.8 US fl oz) of water at 80 to 92 °C (176 to 198 °F) and a steeping time of 30 to 60 seconds.[citation needed]

Inverted[edit]

Baristas and coffee drinkers have also developed methods of brewing using the AeroPress with an inverted brewing technique.[12][13]

In inverted brewing, the plunger is placed into the column from the beginning, close to the "top" of the column, and the entire AeroPress stands upside-down, resting on the top of the plunger. One or two scoops of ground coffee are added, followed by water, and the entire mixture then stirred. While that brews, a filter is placed into the filter cap and moistened to help it stick in place then the AeroPress cap is placed on top of the column and screwed into place. Lastly, once the desired brewing time is complete the AeroPress is either turned right-side-up and plunged normally or held at an angle and plunged horizontally.

This method is more similar to the French press, particularly the extended brewing time in which the grounds and water sit together. This makes it useful for using grinds that wouldn't be optimal in the official method such as coarse grinds that might be used in a French press.

Traditional method coffee properties[edit]

  • Claimed to have roughly the same concentration as espresso[14]
  • Higher pH (thus lower acidity) than drip coffee[15]
  • 30-second total brewing time[15]

Contrasts to other immersion brewing methods[edit]

The AeroPress uses finely ground bean, has a short brewing time of 30 seconds and, similar to espresso, uses air pressure to extract flavor. French press uses a much coarser grind and consequently has a much longer brewing time of 4–5 minutes. French press utilizes a metal filter and is unpressurized. Siphon brew uses intermediate fine grinds and has a 90 second brewing time, using a cloth filter, and is also unpressurized. Espresso runs high temperature water at very high pressure through ultra-finely ground coffee. In contrast to the Aeropress, the water is pressurized mechanically, instead of through muscle power.

To lower the environmental footprint, reusable metal mesh filters exist for the Aeropress, though Aerobie does not recommend reusable filters, saying that coffee made with paper filters has tested better for taste.[16]
