The GS3 from La Marzocco is designed to capture the romance of classic espresso production. Whether you’re a homeowner or business owner, adding this espresso machine to your kitchen is guaranteed to provide superior coffee service. You can now manually manipulate the brew pressure in the full range from 0 to 9 bars, even when operating from a water reservoir. Additionally, a new manometer has been added that sits atop the group head in order to measure the brewing pressure at the point of brewing instead of inside the boiler.
