The three-group GB5 S pairs La Marzocco's most design-led commercial chassis with the capacity to run a genuinely busy bar. Gracious lines and a low cup-rail profile up front; a 5 L coffee boiler, an 11 L steam boiler and three saturated groups behind them.
Engineering worth paying for
- Saturated groups in stainless-steel precision castings: each group is in permanent thermal equilibrium with the coffee boiler, so brew temperature does not drift across positions or across a rush. Machined castings are where the GB5's service life comes from.
- Dual insulated boilers: 5 L coffee and 11 L steam, running independently, so two baristas on milk never pull temperature out of the brew circuit.
- Piero group caps (AV and ABR): a re-engineered internal water path and repositioned flow meter that improves dose accuracy and makes the group easier to service.
- Dual PID: independent PID control on the coffee and steam boilers, adjusted from the digital display.
- Dimmable barista lights (AV and ABR): group lighting set to the room rather than fighting it.
- Hot water economizer and easy-rebuild steam valve: tea water at the right temperature without dumping steam pressure, and a steam valve rebuildable in minutes.
- Eco mode, 24 V electronics, USB firmware and Pro App connectivity: scheduled standby, low-voltage control circuits, and remote monitoring and diagnostics.
Choosing your configuration
- EE (Semi-Automatic): the barista starts and stops each shot. Fewest electronics, lowest entry price.
- AV (Auto-Volumetric): programmable volumetric doses per group with Piero group caps and flow-meter control — the practical baseline at three groups.
- ABR (Auto Brew Ratio): precision drip-tray scales with Drip Prediction technology, which compensates for coffee still dripping after the pump stops. Programme a ratio and the machine hits it by mass.
Best suited to
High-volume specialty cafés, hotel lobbies and restaurant bars where the machine is on show, roastery flagships, and multi-barista sites that want the full technology package in a lower silhouette than the Linea.
Pro Touch cool-to-touch steam wands are available to special order on the S (standard on the GB5 X). Requires a dedicated 50 A circuit. Contact us to confirm current lead time.
