A comprehensive update to the technical and stylistic workings of an industry icon.
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, coupled with cutting edge performance. The new GB5 S features a revamped visual identity which modernizes the machine without sacrificing the look, premium feel, or dynamic elegance. The two red lilies on the side shields recall the company’s Florentine heritage while the front panel has been redesigned to increase group visibility. 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.
