Espresso Machine

La Marzocco



The GB5 S is the last machine designed under the supervision of our honorary president Piero Bambi, and has been designed with refined lines that echo the original. The GB5 S also has vacuum-insulated double-walled steam wands, Luminaire electronics (like on the PB and KB90), piero group caps, and dimmable barista lights, among many other features. You’ll also find the easy-rebuild steam valve that we premiered on the KB90 as well as partially exposed groups to streamline barista workflow!

Equipped with proprietary La Marzocco electronics and advanced temperature stability, the GB5 S combines classical European design with cutting edge performance. The machine has been modernized since its original release in 2005 and is an elegant companion to any coffee bar. The two red lilies on the side shields recall the company’s Florentine heritage, while partially exposed groups offer a streamlined barista working experience. The machine provides the barista control over boiler temperature, brewing volume, hot water tap dose, automatic cleaning cycles and more to keep high quality coffee flowing even during the busiest hours.

Classic Italian design

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 lily, subtle insignia of La Marzocco on the cup rail and more combine to give this machine the feel of an heirloom built to stand the test of time.
