The three-group Strada S brings the Strada's extraction control to a bar that needs real capacity. Three independent saturated brew boilers, an 11.8 L steam boiler, programmable pre-infusion on every group, and three different ways to end a shot.
Where the Strada S pulls ahead
- Three independent 1.3 L saturated boilers: each group has its own 800 W element and its own PID target. Run a light single origin, a house blend and a decaf at three different brew temperatures at once.
- Programmable pre-infusion per group: a low-pressure saturation phase set independently on each group to suit the grind and the roast — the most effective tool against channelling in a high-volume bar.
- Three dosing modes: PULSES for pulsed volumetric delivery, MASS for stopping on weight, and BREW RATIO for dispensing to a dry-dose-to-beverage ratio.
- 11.8 L steam boiler at 4000 W with a proportional solenoid steam valve: capacity for two baristas on milk continuously, with a valve that modulates rather than simply opening.
- Pro Touch cool-to-touch steam wands as standard.
- Connected: IoT connectivity with the La Marzocco Pro App, plus Mahlkönig Grind-by-Sync compatibility so the grinder follows the machine.
Choosing your configuration
- AV (Auto-Volumetric): programmable volumetric doses per group with flow-meter control.
- ABR (Auto Brew Ratio): adds precision drip-tray scales, unlocking MASS and BREW RATIO modes properly. Programme a ratio and the machine dispenses to reach it by weight.
Best suited to
High-volume specialty cafés, roastery flagships, multi-roaster programmes, and training and competition environments that need three groups without giving up extraction control.
Note on pressure profiling: the Strada S is the auto-volumetric Strada. If you need programmable pressure curves, that is the Strada X. Requires a dedicated 50 A circuit (NEMA 6-50). Certified UL-197, NSF-8 and CAN/CSA-C22.2 No. 109.
