La Marzocco GB5 Semi Automatic Commercial Espresso Machine

The La Marzocco GB5 Semi Automatic was named for Giovanna Bambi, Piero Bambi’s wife. It was designed with the classic La Marzocco styling and spirit. It combines harmonious aesthetics and powerful technological advancements with gracious lines and curves. The GB5 is an understated companion to any coffee bar, while its unmatched temperature stability provides steady brew water and steam even at the peak of the morning rush.


The PID Controller employs an algorithm to regulate when and for how long the heating element is engaged in the brew boiler. The PID controller allows more efficient and stable regulation of energy. With this level of control, temperature variability is reduced dramatically, making for a more consistent brew temperature. The barista is able to adjust the brew boiler temperature to a precise numerical value using a simple keypad without having to remove machine panels.
