Elegant design married with proven reliability.

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 gracious lines and harmonious curves of the GB5 S speak to the La Marzocco heritage of design and intention. The understated side shields, elegant Florentine lilies, and subtle insignia of il marzocco on the cup rail, combine to give this
machine the feel of an heirloom built to stand the test of time.
