La Marzocco GS3 (Volumetric)

This version of the GS3 from La Marzocco uses an electronics package that allows for accurate & repeatable shots that can be programmed by water volume. With this machine, it’s able to count and measure the precise amount of water that passes through the group head, and can be programmed by a user to dispense that same amount each & every time. Not only is this machine a powerhouse, but its look is customizable from top-to-bottom including the side panels, the portafilter, as well as the group cap.

Espresso Machine

La Marzocco



This version of the La Marzocco GS/3 Espresso Machine uses an electronics package that allows for precise & repeatable shots that can be programmed by water volume. The GS/3 MP version gives you manual control over the pre-infusion and brewing times with a paddle valve control.

Think consistency when it comes to this GS/3 AV. It uses an electronically controlled espresso system, utilizing the same electronics package as the GB5 AV to actuate the pump and the group's solenoid valve to create the appropriate pressure to extract coffee. The electronic control is what actually enables the volumetric functions of the La Marzocco GS/3 Espresso Machine. Attached to the cold water side of the boiler is a small wheel (flow meter) that spins when water passes through. The AV is able to count and measure the precise amount of water that passes through the group head and can be programmed by a user to dispense that same amount each time.

The AV also has a few more bits of functionality thanks to the electronics. 1st - the ability to program pre-infusion times into each button. The machine allows you to pre-infusion for 4 seconds, rest for 5 seconds, and then begin brewing. Whether plumbed in or not, pre-infusion is accomplished by quickly engaging the pump for 1-5 seconds (adjustable for each AV preset), then disengaging it for 1-5 seconds, then engaging the pump for brewing, which is able to replicate a smooth pre-infusion pressure cure." - La Marzocco Home

Cool Touch Steam Wand

The cool touch steam wand has changed to improve both convenience and steaming power. It has been replaced from Teflon tubing to a double-walled steel cool-touch wand. This combines the performance of the Pro Steam wand with the convenience of the cool touch wand. With this change, the Pro Steam wand option will no longer be an option on the GS3. This will also be standard on the GS3 AV model.

The La Marzocco GS3 is highly customizable, allowing you to change out nearly everything, from the side panels to the portafilter to the group cap. Contact us today to see the many optional accessories to meet your tastes.
