Founded in 1927 by brothers Piero and Giuseppe Bambi in their home city of Florence, La Marzocco has been manufacturing some of the highest quality commercial machines available since that time. They primarily build machines for cafes, and the GS/3 is no exception. The La Marzocco GS/3 AV is a commercial espresso machine in a small enough footprint to sit on your kitchen countertop. With a machine this powerful in your kitchen, your home will quickly become your favourite cafe.


La Marzocco’s GS/3 is one of the best home machines available today, and its powerful boilers and state of the art heating systems provide the true experience of a cafe in your kitchen. Unlike most other dual boiler machines, the GS/3 uses a saturated brew group in order to perfectly control the temperature of your extraction. This version of the machine is equipped with auto volumetric (AV) control, giving you the tools to create the perfect espresso shot with ease, and conveniently recreate each shot with volumetric controls.

La Marzocco was founded in 1927 by brothers Bruno and Giuseppe Bambi in Florence, Italy. Innovation and originality set La Marzocco apart from the competition, and their past contributions to the manufacturing of espresso machines have helped to shape today’s industry standards. Set up your favourite cafe in your own kitchen with the GS/3 AV, one of the most powerful home espresso machines on the market.

Combining a saturated brew group with a powerful 3.5L steam boiler, PID for temperature control, volumetric controls, adjustable brew pressure, and smartphone compatibility, this fully equipped commercial quality machine provides the best experience in terms of quality and convenience.

A programmable start time, remote on and off, temperature control, and pre-infusion setting are just a few of the many features available through the GS/3’s smartphone app, making it one of the more advanced machines we carry while still preserving the analog beauty of a traditional commercial espresso machine.

Our Assessment

Ease of use - moderate.
Size - extra large.
Best used for - espresso shots, americanos, and milk-based drinks such as lattes and cappuccinos, hot chocolate, etc.
Serviceability - excellent


A large, 3.5L steam boiler combined provides commercial grade steam power.
A saturated group and 1.5L coffee boiler create superior temperature stability. Saturated groups create the best possible temperature stability, for the best possible espresso shots.
The GS/3 uses a commercial-grade rotary pump. With the included plumb-in kit, you can avoid the inconvenience of having to refill a water reservoir daily. Without one, the reservoir is accessible from the front of the machine so you can refill the GS/3 without having to move it out from under your cupboards.
The machine’s PID (or digital thermostat) control monitors boiler temperature, holding it within a couple of degrees all day long so the machine is always ready to brew the perfect shot.
Programmable volumetric controls make it easy to repeat your results time after time.
Adjustable brewing pressure with the machine’s externally accessible expansion valve.
The GS/3 now comes standard with La Marzocco’s ‘connected machine’ feature. Using their smartphone app, you can program the machine to automatically turn on or off, adjust brewing temperature, adjust the pre-brewing feature, and more.


What is a saturated grouphead?

The GS/3 uses a saturated grouphead. This means that instead of water traveling from the boiler through the machine to reach the group, the group is constantly surrounded by water from the boiler. The grouphead becomes an extension of the coffee boiler. This eliminates temperature instability, and translates to more stable and consistent tasting espresso shots.

What’s the difference between the GS/3 AV and MP?

The GS/3 AV (auto volumetric) is equipped with volumetric controls so you can program your desired shot length and trust the machine will keep it consistent. The MP (mechanical paddle) model is equipped with a paddle control on the top of the grouphead, allowing you to experiment with pre-infusion times and volumes, making every shot unique.

Does La Marzocco make the best machines?

La Marzocco makes some of the best espresso machines available both for home and commercial purposes. Working with commercial grade materials, and building their machines to both make the best possible espresso and last the longest possible time, there are few manufacturers who can compare themselves to La Marzocco’s reputation.
