The La Marzocco GS3 is a professional-grade espresso machine that brings La Marzocco’s commercial technology into a compact platform designed for small cafés, offices, and advanced home baristas. It features the same thermal stability system used in La Marzocco’s commercial machines, including saturated group technology, dual boilers, and advanced temperature control.

The GS3 is available in two versions:

• MP (Mechanical Paddle) – manual pressure control for espresso profiling.

• AV (Auto-Volumetric) – programmable dosing for consistent and repeatable shots.

  Key Features

  • Dual Boiler System – Separate boilers optimize espresso brewing and steam production.

  • Saturated Group Head – Improves temperature stability and extraction consistency.

  • Dual PID Temperature Control – Independent electronic control for brew and steam boilers.

  • Pre-Heating System – Incoming water is pre-heated before entering the brew boiler to enhance productivity and thermal stability.

  • Ruby Flow Restrictors – Designed to resist scale buildup and wear.

  • Digital Display – Shows temperature, shot timers, and machine settings for easy adjustment.

  • Performance Touch Steam Wand – High-performance steam wand designed to remain cool to the touch.

  • Internal Pump – Allows the machine to operate with a water reservoir or direct plumbing.

  • Water Reservoir – Integrated tank allows operation without permanent plumbing.
