The GB5 has redefined the standard for temperature stability in modern espresso equipment.

Equipped with a CPU board and designed for superior temperature control, the gb5 combines gracious lines and harmonious curves with powerful technological advancements, in line with classic La Marzocco design and spirit. The machine is an understated companion to any coffee bar. Its unmatched temperature stability provide steady brew water and steam even at the peak of the morning rush. The gb5 has redefined the standard for temperature stability in modern espresso equipment in light of “PID” technology.

Manufactured by
Mechanical Paddle

The mechanical paddle is inspired by the original mechanical group used on the La Marzocco GS – the first dual-boiler espresso machine with saturated groups (1970). This valve system enables the barista to saturate the coffee with low pressure (line pressure) water before applying the full 9 bars of pressure. While more complex, this dynamic system allows the barista to control the variable of pre-infusion and reduce channeling for a more balanced extraction.

Dual Boilers

Separate boilers optimize espresso brewing and steam production.

Saturated Groups

Digital Display

Intuitive programming makes it easy to adjust machine parameters.

Hot Water Economizer

Enables you to fine-tune the tap water temperature for tea.

Dual PID (coffee and steam)

Allows you to electronically control coffee and steam boiler temperature.

Ruby Flow Restrictors

Ruby flow restrictors resist scale formation and erosion.

Portafilters & Precision Baskets

Stainless steel portafilters and precision baskets improve your cup quality and consistency.

Cup Warmer*
