Mypressi Twist

“The mypressi TWIST is a portable espresso machine. It produces quality espresso while giving espresso lovers convenience and portability. The TWIST’s unique pneumatic engine also ensures you can enjoy incredible coffee even where there is no external power. Just add hot water… ”

The portable espresso maker is powered by using a pressurize cylinder to power the shot with constant pressure all the way through the extraction cycle. It uses fresh espresso or an ESE pod in the holder, add water, and pull the shot. The CO2 cartridge does the rest, offering a 9-bar pressure across the entire shot. Each cartridge lasts for about 8 shots of espresso.
For something more manual try Handpresso. So which is better?
