La Marzocco GS3 Home Espresso Machine - Dual Boiler

Authorized La Marzocco dealer. Berkeley-rooted since 2011 — we service every La Marzocco we sell, including diagnostic equipment for commercial models. The GS3 is the bridge between Lelit Bianca-tier prosumer and full commercial: same saturated group architecture as the Linea PB on our café floor, sized for a serious home setup.

The GS3 brought commercial dual-boiler technology into the home. Independent brew and steam boilers deliver perfect temperature stability, while the iconic design and handcrafted build quality have made it the benchmark for serious home espresso since 2008.

☕ Pair with fresh beans. A GS3 deserves coffee worthy of it. We carry Zolo Coffee single-origin beans from our Berkeley neighbor roastery — light-roast specialty coffee that extracts beautifully on the GS3's saturated group.
