Picopresso is the most compact and pro-oriented of our portable espresso machines. This specialty coffee espresso machine features a naked portafilter, so users will see delicious creamy espresso flowing directly from a standard 52mm 18 grams stainless steel filter basket during the brewing process. With the Picopresso there are no shortcuts. Each home brewer must master the art of manual espresso making by dialing in the correct grind size, tamping, and perfecting pulling technique ? their reward; an authentic cafe-quality espresso that will rival any expensive high-end machine.
