The AeroPress is a new take brewing coffee invented by Aerobie, the company that holds the Guinness world record for longest frisbee toss.
1,333 feet!
Similar in concept to espresso machines, the AeroPress combines coffee grounds, hot water and pressure to aid extraction. The pressure is generated completely by hand as you compress the coffee between the plunger and the ground coffee bed/micro-filter.
You won’t generate the 9 bars required for authentic espresso, but Aerobie says you can generate between 0.35-0.70 bar. That sounds small, but it’s the reason you can speedily make espresso-like concentrates.
