La Marzocco GB5 S Espresso Machine

With a history dating back to 2005, the second generation GB5 carries on the spirit of the GB5 line: a machine rooted in classical European design, combined with advanced performance. The new GB5 S features a refreshed visual identity that modernizes the machine without sacrificing its premium feel and elegance. The two red lilies on the side shields reference the company’s Florentine heritage, while the redesigned front panel improves group visibility. The second generation GB5 is the first La Marzocco series equipped with a water sensor that measures conductivity and hardness as water enters the machine, allowing users to monitor water quality without additional tools.
