COMPANY: Decent Espresso

Decent Espresso is a company based in Hong Kong, San Francisco and Seattle. They build espresso machines that are controlled from a touch-screen tablet. Users have control over temperature and pressure. Data are recorded along with parameters such as flow rate, ambient humidity, and the actual temperature in the grouphead (using a thermo probe). So custom results can be replicated.
