The GB5 X is designed with traditional European style and is dedicated for those locations with an eye on classic aesthetics but that still demand the highest level of performance. The GB5 X can be identified by the white logos and lilies, it combines advanced La Marzocco proprietary electronics with the industry-leading temperature stability and hydraulic systems to always ensure maximum consistency. The machine features independent boilers allowing for different brewing temperatures on each group; a convenient hot water economizer to set the hot water temperature as well as a dynamic pre-heater for additional and unsurpassed temperature stability. In ABR configuration the GB5 X is La Marzocco’s most elegant machine equipped with patented scale technology. The second generation GB5 is the first series of La Marzocco machines equipped with a water sensor that measures the conductivity and hardness of water as it enters the machine. This information allows the user to monitor water quality and verify filtration performance without the need for additional testing tools.
