The Mazzer ZM is the official grinder of the World Brewers Cup 2023–25 and the must-have machine for specialty coffee programs. A motor-operated digital grind adjustment system lets the barista control burr distance in microns — so grind setting is understandable, accurate, and repeatable. Electronic True Zero calibration keeps grind settings identical from grinder to grinder, while excellent burr parallelism delivers consistent particle size distribution. Retention under 0.45 grams makes single dosing a clean workflow.
