It has become an iconic design, displayed in modern industrial art.
Barista Moka Nero brews coffee by passing boiling water pressurized by steam through ground coffee. The steam reaches a high enough pressure to gradually force the surrounding boiling water up the funnel through the coffee powder and into the upper chamber, where the coffee is collected.
With the Barista Moka Nero, the result is coffee brewed at a higher pressure and temperature than the standard pot, making it more similar to espresso and therefore with more visible crema.
