La Marzocco GS3 – The Flagship Single Group
The GS3 is La Marzocco's top-end single-group machine, built for serious home baristas, offices and smaller professional environments. Rather than a scaled-down imitation, it takes the engineering from La Marzocco's commercial machines – dual boilers, a saturated group and a rotary pump – and packages it into a self-contained machine that sits comfortably on a countertop. If you want the closest thing to a café machine without installing one, this is it.
Choosing your GS3
The GS3 comes in two versions, and the right one depends on how you like to work.
AV – Auto Volumetric: programmable volumetric dosing lets you set your shot volumes once and repeat them at the touch of a button. The practical choice if you value consistency and ease of use, or if more than one person will be using the machine.
MP – Manual Paddle: a mechanical paddle gives you hands-on control of pre-infusion and pressure profiling on every shot. The choice for baristas who want to work the extraction themselves.
Both versions share the same boilers, group and build quality – the difference is purely in how you control the shot.
