La Marzocco GS3 Espresso Machine Semi Automatic

La Marzocco GS3 Features

The GS3, available in both Manual Paddle (MP) and Auto Volumetric (AV) configurations, brings advanced La Marzocco technology to the home espresso machine market. Designed for the discerning barista, it offers exceptional control, thermal stability, and performance.

Manual Paddle (MP) Version:

The MP configuration features a conical valve system that provides 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 works at full pressure, allowing the barista to perform pre-infusion on one group while extracting coffee with the other. This system reduces channeling for a more balanced extraction.

Auto Volumetric (AV) Version:

The AV configuration translates La Marzocco’s advanced technology into a home machine, featuring auto-volumetric controls for the perfectionist. This system simplifies the brewing process while ensuring precision and consistency.

Shared Features:

• 3.5 Liter Dedicated Steam Boiler: Ensures powerful steam production.
• Performance Touch Steam Wand: Provides more powerful steam and remains cool to the touch.
• Dual Boilers: Optimize espresso brewing and steam production with saturated groups to ensure thermal stability shot after shot.
• Dual PID Controllers: Allow electronic control of coffee and steam boiler temperatures, with a thermal stability system that further stabilizes water temperature as it passes through each feature.
• Digital Display: Offers intuitive programming for easy adjustment of machine parameters.
• Optional Plumbing: Features a self-contained 3.5-liter water reservoir, and a hot water economizer to fine-tune tap water for rinsing.
• Ruby Flow Restrictors: Resist scale formation and erosion, prolonging the machine’s life.
• Self-Contained Internal Pump: Simplifies installation and operation.

Unique to MP Version:

• Manual Paddle: Allows the barista to manually control pre-infusion and extraction, providing a hands-on experience.
• Conical Valve System: Improves longevity and allows increased pressure manipulation.
• Periscope Pressure Gauge: Enables the barista to monitor coffee pressure during extraction.

Unique to AV Version:
