A Lasting Legacy

La Marzocco is one of the most trusted and reliable names in espresso machines, used the world over. With nearly a century of innovation, the GS3 AV (auto-volumetric) is the culmination of commercial components and offers unrivaled consistency over every shot of espresso. The GS3 AV allows the user to program a desired espresso dose through the control panel and receive the same volume with each subsequent shor. The GS3’s programmable temperatures at 0.1º F, dual boilers, and powerful steam capabilities put all of the elements of a true, cafe-quality espresso machine at your fingertips.

For The Perfectionist

Few other machines offer the amount of control that the La Marzocco GS3 does, making it a highly sought-after machine for serious home baristas. The GS3 AV utilizes the same exact same technologies found in La Marzocco's commercial machine's, such as the GB5 AV, the activate the machine's pump and solenoid valve to create the 9 bars of pressure used to pull espresso shots. After the preferred recipe is programmed, the GS3 AV measures the amount of water that passes through the group head and, essentially, "remembers" this recipe, allowing the user to focus on other tasks while the shot of espresso is being pulled.

Commercial Features & Stability

The GS3 AV is outfitted with commercial components built by, or exclusively for La Marzocco, and the steam wand is no exception. Thanks to a 3.5L dedicated steam boiler, this machine is capable of producing powerful, cafe-quality steam for back-to back drinks. This double-insulated, articulating steam wand is also safe to touch while steaming, eradicating accidental burns. The hot water tap, on the other hand, utilizes a mix valve, allowing you to easily combine hot water from the steam boiler and cool water from the 2.5L reservoir to give you a more desirable water temperature for teas and Americanos.
