AeroPress and included accessories (filter papers not shown)

The AeroPress is a device for brewing coffee. It was invented in 2005 by Aerobie president Alan Adler.[1] Coffee is steeped for between 10-50 seconds (depending on grind and preferred strength) and then forced through a filter by pressing the plunger through the tube. The filters used are either the AeroPress paper filters or disc shaped thin metal filters. The maker describes the result as an espresso strength concentration of coffee, but its most frequent use is more in the filter brew strength [2]

The device consists of two copolyester cylinders.[3] One cylinder has a rubber plunger and fits inside the larger cylinder to create an airtight seal, similar to a syringe.

Methods of brewing[edit]

Traditional[edit]

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 170 to 190 degrees Fahrenheit or 75 to 85 degrees Celsius 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.[4] In the different coffee competitions world wide (World Barista Championship, Brewers Cup, World AeroPress Championship etc.), the coffee is more often ground slightly finer than 'filter grind', and the dose is between 14 and 20 grams, with about 200 to 230 grams of water at 80 to 92 degrees Celsius and a steeping time of 30 to 60 seconds.

Inverted[edit]

Baristas and coffee drinkers have also developed methods of brewing using an inverted (upside-down) AeroPress.[5][6]

In inverted brewing, the plunger is placed into the column from the beginning, close to the “top” of the column, and the entire AeroPress is stood up upside-down, resting on the top of the plunger. One or two scoops of ground coffee is added, followed by water, and the entire mixture then stirred. While that brews, a filter is placed into the filter cap and wetted to help it stick in place, and the cap then carefully 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, including coarse grinds such as might be used in a French press.

AeroPress coffee properties[edit]

  • Claimed to have roughly the same strength as espresso[7]
  • Higher pH than drip coffee (one fifth as acidic)[1]
  • 30-second total brewing time[1]

Differences from French press[edit]

The AeroPress, though sharing some characteristics with a French press, is quite different:

  • Uses a disposable paper filter which removes most of the coffee solids (a French press uses a coarser wire or nylon mesh filter)
  • Shorter brewing time
  • Uses air pressure to improve extraction of flavour.
  • Uses a fine grind (slightly finer grind than drip, but coarser than espresso machines use), versus the coarse grind recommended for French presses
