The 10-ounce Pipamoka from Wacaco is a compact, all-in-one vacuum pressured portable coffeemaker that enables you to brew and drink from a single device anywhere you go. It’s a simple, sturdy pressure brewer that yields hot, freshly-brewed coffee in just 2 minutes using its innovative twisting mechanism to generate vacuum pressure inside the mug. The negative pressure generates a suction force that draws hot water downwards through the coffee grounds & voilá, you’ve got a quality brew in the palm of your hand.
