La Marzocco GS3

Professional-grade espresso equipment,

built for the 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.

The Auto Volumetric model allows for programmable pre-infusion and water metering that makes hitting targeted brew ratios easy and repeatable. The Auto Volumetric model also has a auto clean function for back flushing to keep your machine clean and coffee tasting great.



Dual Boilers

Separate boilers optimize espresso brewing and steam production.

Saturated Group

Ensure unsurpassed thermal stability, shot after shot.

Digital Display

Intuitive programming makes it easy to adjust machine parameters.

Hot Water Economizer

Enables you to fine-tune the tap water temperature for rinsing.

Thermal Stability System

As water passes through each feature, temperature is further stabilized.

Internal Pump

Self contained pump without compromising performance.

Dual PID (coffee & steam)

Allows you to electronically control coffee & steam boiler temperatures.

Water Reservoir

A self contained 3.5 liter water reservoir makes plumbing optional.

Ruby Flow Restrictors

Ruby flow restrictors resist scale formation and erosion.

Half Power Mode

Allows your machine to run on a 15amp circuit.

Periscope Pressure Gauge (MP only)

Monitor pressure at coffee during extraction.

Conical Valve (MP only)

Improved longevity and increased pressure manipulation ability.
