The AeroPress was invented by Aerobie president and Stanford lecturer Alan Adler. The AeroPress uses more finely ground coffee than a v60 and has a shorter brewing time than most manual brewers. Similar to an espresso machine, the AeroPress uses air pressure to extract the coffee. One interesting thing to point out is that Aerobie is also a company that produces flying rings, similar to a Frisbee! The Aerobie has been used to set two former world records for thrown objects.
When preparing an AeroPress coffee there are two main methods: the inverted method and the standard method. This recipe will focus on the standard method which is seen on the picture.
Insert a paper filter into the AeroPress's removable plastic cap. We always recommend pre-wetting the filter paper before the start of your brew.
Bring 250g (9oz) of water to a boil. Weigh out 15 grams of coffee and grind to a texture that is slightly finer than a sea salt like consistency.
Assemble the bottom half of your AeroPress by twisting in the removable cap whilst ensuring the internal tube is dry. Any moisture could compromise the seal of the device.
Place the assembled bottom half of the AeroPress over your cup and add the ground coffee. The AeroPress brings a black plastic funnel to avoid any spillage when adding the coffee.
Start a timer. Add water up to the number "4." We recommend using water that is as hot as possible right off the boil.
Make sure the coffee is fully saturated by gently stirring with a paddle or butter knife for around 5 seconds. Straight after quickly add the top half of the AeroPress.
Let the coffee sit for 1min and 20sec. By adding the top half of the AeroPress, the seal prevents any water from escaping from the bottom into your cup.
After the time has elapsed, remove the top of the AeroPress and once again stir the coffee for around 5 seconds.
Finally, add the top back on and begin the extraction by adding downward pressure until you hear a 'hissing' sounds. This means all the water has passed and your coffee ready! You will experience a resistance of around 30 pounds when you are pushing down. If the push feels too easy it is likely the grounds are too coarse of the seal has been lost somewhere. If the resistance feels too hard then the grounds might be too fine.
