Professional-grade espresso equipment, built for home. La Marzocco technology and performance in an elegant, self-contained footprint. 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.   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.
