La Marzocco Linea Classic S Commercial Espresso Machine (3 Group)

The Linea Classic S in three groups is built for cafés where the queue does not stop. It carries the original 1990 Linea silhouette forward on a modern platform: dual insulated boilers, saturated group heads and independent PID control on both the coffee and steam circuits. Three groups plus an 11 L steam boiler gives you the headroom to run two baristas flat out without the machine falling behind.

Why the Classic S earns its place

• Saturated group heads: each of the three groups sits in permanent thermal equilibrium with the coffee boiler rather than being heated separately, so brew temperature holds steady across all three positions even under sustained load.
• Dual insulated boilers: a 5 L coffee boiler and an 11 L steam boiler run independently, so two baristas texturing milk simultaneously never pull temperature out of the brew circuit.
• Dual PID control: separate PID controllers on the coffee and steam boilers let you dial brew temperature to the roast and set steam pressure to suit your milk programme.
• Half-turn steam valve: a 180° lever gets you from closed to full steam in one motion — a real time saver at three-group volumes.
• Water conductivity sensor: the machine monitors incoming water hardness and conductivity, giving you early warning before scale becomes a service call.
• La Marzocco Pro App: the electronic board supports connectivity with the Pro App for remote monitoring, scheduling and diagnostics.

Choosing your configuration

• EE (Semi-Automatic): a single on/off switch per group. The barista controls the shot by eye and by scale. Simplest to operate, fewest electronics to service.
• MP (Mechanical Paddle): a manual paddle per group giving direct control over pre-infusion and flow. No volumetric dosing and no electronics in the shot path — the pick for baristas who want to feel the extraction rather than programme it.
• AV (Auto-Volumetric): programmable volumetric doses per group with flow-meter control, so every shot stops at the same yield regardless of who is on bar. Strongly recommended at three groups.

Best suited to

High-traffic cafés and coffee bars, hotel and restaurant service, campus and hospital sites, and any bar running two or more baristas through a sustained morning peak.
