GB5 S 3 Group Espresso Machine by La Marzocco

Please contact us for availability, lead times 4+ weeks on some LM machines.

The new GB5 S is modernized inside and out with a classic look, premium features, and innovative technology and is an upgraded version of the original that was developed and released in 2005. This commercial espresso machine is equipped with proprietary La Marzocco electronics and advanced temperature stability, the GB5 S combines classical European design with cutting edge performance.

Styled Winning Heritage

The gracious lines and harmonious curves of the GB5 S speak to the La Marzocco heritage of design and intention. The understated side shields, elegant Florentine lilies, subtle insignia of il marzocco on the cup rail, combine to give this machine the feel of an heirloom built to stand the test of time.

Light It Up

This newly designed espresso machine features 3-stage LED lights for eco, on, and brewing modes allows you to focus on your extraction and the cup. No more working in the dark, your baristas will love working it lit conditions.

Automatic Dosing

With volumetric dosing you are able to program (4) doses and have your brews ready at the press of a button. This allows your baristas to multi-task and helps with baristas that aren't trained up as well. Keep your extractions precise and consist with the ease of a button.

Dual Boiler System

Separate boilers for each group allows for the optimization of espresso brewing and steam production. Combined with insulated boilers, you have a machine that not only delivers power and stability but also energy savings

Dual PID and Increased Thermo-stability

The GB5 S has dual algorithm-based PID temperature controller further reduces temperature fluctuation in the coffee and steam boiler. A group cap designed by Piero Bambi and an integrated ruby flow restrictor reduces channeling and ensures that water never leaves the saturated area of the coffee boiler; this eliminates the introduction of temperature instability during the brewing process.

Performance Touch Steam Wands

Another upgraded part in the GB5 S is the vacuum-insulated double-walled steam wands which remain cool to the touch while delivering high volume dry steam. Work with peace-of-mind that these no-burn wands will help alleviate the nuisance of getting burned while moving the wands.

ABR - Auto Brew Ratio (optional)

With integrated scales in the drip tray, the GB5S-ABR lets barista brew by volume, mass, or brew ratio to suit their workflow. Precision scales incorporated into the drip tray improve beverage consistency by stopping the extraction based on mass. The machine uses an algorithm called Drip Prediction to improve shot accuracy and ease of dialing in.
