AeroPress and included accessories (filter papers not shown)
The AeroPress is a device for brewing coffee. It was invented in 2005 by Alan Adler[1]. Coffee is steeped for about 10 seconds and then forced through a paper microfilter. The maker describes the result as an espresso strength concentration of coffee, but others consider it more like strong coffee [2].
The device consists of two polycarbonate cylinders. One cylinder has a rubber plunger and fits inside the larger cylinder to create an airtight seal, similar to a syringe. Fine-ground coffee is placed in the bottom of the larger cylinder on top of a paper microfilter. Hot water (170-190 degrees Fahrenheit) is then poured over the coffee, this mixture is stirred and allowed to steep for approximately 10 seconds before being forced through the microfilter using air pressure generated by pushing the second cylinder downwards.[3].
