La Marzocco Linea Classic S 3 Group Commercial Espresso Machine

High-capacity professional 3-group commercial espresso machine with dual boilers, saturated groups, dual PID temperature control, and EE or AV configuration options.

The La Marzocco Linea Classic S 3 Group is a professional commercial espresso machine designed for busy cafés, coffee shops, roasteries, restaurants, and other high-volume coffee programs. Building on the proven Linea Classic platform, the Linea Classic S combines its recognizable clean design with updated controls and technology focused on reliability, consistency, and efficient barista workflow.

The 3-group configuration provides additional brewing capacity for demanding service environments while maintaining the thermal stability and dependable performance associated with the Linea Classic. Separate coffee and steam boilers optimize espresso brewing and steam production, while saturated groups help maintain consistent temperatures from shot to shot.

Dual PID controls allow the coffee and steam boiler temperatures to be electronically controlled independently. The 3-group model features a 5-liter coffee boiler and an 11-liter steam boiler, providing substantial capacity for high-volume espresso preparation and milk steaming.

The Linea Classic S is available in EE (semi-automatic) and AV (auto-volumetric) configurations. The EE configuration allows the barista to manually start and stop each extraction, while the AV configuration uses programmable doses to automatically stop extraction at the programmed volume for increased repeatability and consistency during high-volume service.

Design & Build

The Linea Classic S builds upon the long-standing Linea Classic platform, which has served cafés, roasteries, and coffee chains for decades. Its clean, understated design is paired with commercial components engineered around reliability, consistency, and efficient barista workflow. The Linea Classic S continues the platform's focus on being reserved, reliable, and consistent while introducing features designed to make coffee preparation easier for baristas.

The 3-group model measures 36.6 inches wide, 23 inches deep, and 17.5 inches high, with a weight of approximately 161 lbs. Its separate 5-liter coffee boiler and 11-liter steam boiler optimize espresso brewing and steam production, while Dual PID controls provide electronic temperature management for both boilers.

Saturated groups help provide thermal stability throughout repeated extractions, while insulated boilers help reduce energy consumption and contribute to temperature stability. The ½-turn steam valve fully opens with only half a turn, reducing the amount of movement required by the barista during milk steaming. 

EE vs. AV Configuration

EE – Semi-Automatic: The EE configuration gives the barista manual control over the extraction. The barista starts and stops the shot using the machine controls, making it suitable for operations that prefer direct control over espresso volume.

AV – Auto-Volumetric: The AV configuration features programmable doses. The barista starts the extraction and the machine automatically stops at the programmed volume, helping improve repeatability and consistency during high-volume service. AV models also include digital shot timers positioned above the control buttons to monitor extraction time.
