Coffee machine La Marzocco “Linea GB5 S”, 3 groups

Elegant design paired with proven reliability.

With its history dating all the way back to 2005, the second-generation “GB5” model is designed to carry on the spirit of the original “GB5” line. This is a machine rooted in classic European design, coupled with cutting-edge performance. The new “GB5 S” features a revamped visual identity that modernises the model without sacrificing its distinctive look, premium feel, or dynamic elegance. The two red lilies on the sides recall the company’s Florentine heritage. The front panel has been redesigned to increase group visibility. This machine offers baristas control over boiler temperature, brewing volume, automatic cleaning cycles, and much more, all thanks to next-generation proprietary electronics. Moreover, the second-generation “GB5” is the first series from La Marzocco to be equipped with a water sensor that measures the conductivity and hardness of water as it enters the machine, with this information allowing users to monitor water quality and verify filtration performance without the need for additional testing tools.
