Want a fresh, delicious cup of espresso anytime, anywhere, from camping trips to your busy desk at work? The Minipresso is a portable, hand-held, lightweight espresso maker designed to fit in your backpack or coat pocket. Simply add hot water and ground beans and pump the semi-automatic piston to inject small quantities of water into the coffee adapter. After a few pushes, the optimal extraction pressure is achieved. The result is a rich and bold espresso, with a quality close to shots made by a traditional machine. Handwash only.
