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 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.
