La Marzocco GS3 AV 1 Group

La Marzocco GS3 AV 1 Group

The La Marzocco engineering group set out to take the most advanced La Marzocco technology and translate it for a home espresso machine. The gs3 features the thermal stability system used in the La Marzocco Strada, including a preheating system, digital PID controller, saturated groups, a dual-boiler system, and digital display. These features make for a luxury espresso preparation platform: everything you could hope for as someone who wants to enjoy the best-quality espresso at home. All that’s left for you to do is to grind, dose, and tamp.

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 channelling for a more balanced extraction.

Dual Boilers
Separate boilers optimise espresso brewing and steam production.

Saturated Groups
Ensure unsurpassed thermal stability, shot after shot.

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.

Thermal Stability System
As water passes through each element, temperature is further stabilized.

Internal Pump
Self-contained pump without compromising performance.

Dual PID (coffee and steam) Allows you to electronically control coffee and steam boiler temperature.

Water Reservoir
A self-contained 3.5 litre water tank makes plumbing optional.

Ruby Flow Restrictors
Ruby flow restrictors resist scale formation and erosion.
