The GB5 S ABR, a second-generation machine rooted in classic European design, blends tradition with cutting-edge performance. La Marzocco's ABR (Auto Brew Ratio) feature, found in machines like the Linea PB ABR and Strada AV ABR, provides baristas with integrated scales in the drip tray to brew coffee by volume, mass, or brew ratio, ensuring consistent and precise espresso extractions. With dimmable barista lights there are 3 stage LED lights used for eco, on and brewing modes. As well there is a Pro app compatible with the machine allowing any barista to have control functions of the machine such as coffee boiler temperature and specific usage statistics
