La Marzocco GB5 S

Elevate your coffee shop's performance with the La Marzocco GB5 S, a second-generation machine blending classical European design with cutting-edge functionality. Revamped visuals, a water sensor for quality monitoring, and Luminaire electronics bring this iconic espresso machine into the modern era.

Size and design
The GB5 S marries timeless elegance with contemporary aesthetics. Redesigned front panels and iconic red lilies pay homage to La Marzocco's Florentine heritage, ensuring it's not just an espresso machine but a statement of premium craftsmanship. The red accents on the buttons and branding make the design a bit bolder and the dimmable barista lights for customizable ambiance allow you to focus on the extraction and cup.

Saturated groups
The GB5 S is equipped with saturated groups, ensuring thermal stability and precise temperature control for each espresso shot, resulting in consistent extraction. It provides a solid foundation for delivering rich, aromatic, and flavorful shots.

The machine is available in different configurations. The number of saturated groups is determined by the specific model you choose
2 groups
3 groups
4 groups

Dual boiler
Experience optimal temperature stability with dual boilers, allowing seamless simultaneous brewing and steaming. Reduce energy consumption with insulated boilers while contributing to temperature stability. The innovative Piero group caps (designed by Piero Bambi) and saturated groups ensure unsurpassed thermal stability for consistent shots.

The boiler for the coffee group heads is a single one. If you would like to have independent boilers for each group head, we advise you to have a look at the La Marzocco GB5 X. It has a lot of the same features as the GB5 S, but some of them were upgraded.

Brew system
The GB5 S features advanced pre-infusion, a ruby flow restrictor, and a performance touch steam wand for superior espresso extraction. Luminaire electronics provide precise control, contributing to an exceptional brewing experience. The easy-rebuild steam valve allows for hassle-free maintenance directly from the front of the machine.

PID controller
Enjoy dual PID control, allowing baristas to fine-tune both coffee and steam boiler temperatures. This level of control ensures optimal brewing conditions and flavor extraction for various coffee profiles. The machine also comes with 24v electronics for improved reliability and diagnostics.

Water sensor
The GB5 S is the first series of La Marzocco machines equipped with a water sensor. This sensor measures the conductivity and hardness of water as it enters the machine, and allows you to monitor water quality and verify filtration performance without the need for additional testing tools.

Optional Pro Touch steam wand
The machine features a normal steam wand. It makes perfectly good velvety milk. You only have to be carful to not scald your hands by touching it during or after milk steaming. 

There is an option to get Pro Touch steam wands on the GB5 S, but it is also worth having a look at the GB5 X if you are looking for this extra option.

Th Pro Touch steam wands are double-walled and vacuum-sealed that deliver a proper temperature and force while remaining cool to the touch. They make velvety microfoam for lattes and cappuccinos with precision. The Pro Touch steam wands are high-performing and cool to the touch.

App integration
Stay connected with the La Marzocco Pro App, providing control over day-to-day functions. Adjust doses, coffee boiler temperature, and access usage statistics for enhanced customization.

EE, AV or ABR
The GB5 S comes in a Semi-Automatic (EE) version, Automatic-Volumetric (AV) version and an auto brew-ratio (ABR) version. 

The EE feature refers to its ability to operate in semi-automatic mode. In this mode, the barista has manual control over the duration of the espresso shot.

The AV feature allows baristas to program the amount of time or volume an espresso shot receives. The machine automatically dispenses the desired amount of coffee.

The Auto-Volumetric with Scales (ABR) uses La Marzocco’s patented Auto Brew Ratio technology and scales built-in to the drip tray. Using this feature, baristas can brew each espresso shot by mass, volume, or brew ratio (for example, a 1:2 ratio with 19g of coffee in and 38g of liquid espresso out.)
