La Marzocco GS3

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. Thanks to the new electronic board, the GS3 can now be connected to the internet and controlled through the new La Marzocco Home App, available on AppStore and GooglePlay.

conical paddle valve
This new conical valve system ensures progressive control of the water flow and pressure via an internal nozzle, before full pressure is applied. The paddle valve controls the pre-infusion, while the volumetric pump operates at full pressure,
which allows the barista to perform a pre-infusion on the group while the other extracts coffee. This dynamic system allows the barista to reduce channeling and achieves a more balanced extraction.
