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.
Available as AV (auto dosing) or MP (conical paddle). A feature on the MP configuration, the conical valve system assures progressive control of water flow and pressure via an internal orifice, before applying full pressure. The paddle valve controls pre-infusion while the volumetric pump is working at full pressure, allowing the barista to perform pre-infusion on one group while the other is extracting coffee. This dynamic system allows the barista to reduce channeling for a more balanced extraction.
For use without plumbed in water supply, the GS3 has a self contained 3.5 liter water reservoir makes plumbing optional.
Wood or Glass Side Panels: $550
