The AeroPress is a deceptively simple device -- it's basically a coffee syringe. The quick-brewing coffee maker sits somewhere between an espresso machine and a French press. You pour hot water over your grounds then force the water through them with a plunger. What makes the AeroPress unique is how quickly it can spit out a high-quality cup of Joe. The entire process takes roughly one to two minutes and at the end you've got a heavily concentrated, smooth mug of coffee. But unlike other modern methods for making a hot caffeinated beverage, the AeroPress was dreamed up by an engineer who spent a good chunk of his career making toys and electronics.
