Step into the world of specialty coffee excellence with the Mazzer ZM Digital Coffee Grinder. Engineered for baristas and coffee professionals, this grinder delivers unmatched precision, flexibility, and consistency—making it ideal for both espresso and filter workflows.
The ZM’s motor‑driven digital grind adjustment enables you to control the burr gap in microns, giving you a grind setting that’s understandable, repeatable, and reliable. Thanks to True Zero electronic calibration, you can standardise grind settings across multiple ZM units — a game-changer for multi-grinder setups.
Its 83 mm flat special steel burrs provide excellent particle size distribution and consistency — whether you're dialling in for espresso or filter. And with a retention of under 0.45 g, this grinder is perfect for single-dose workflows, minimising waste and maximising flavour clarity.
Durability and workflow efficiency are core to the ZM’s design. It features a double-fan cooling system to manage temperature, a lockable canister to keep grounds off your counter, and a digital display that flips aside for quick access to the grinding chamber—ideal for regular cleaning and burr replacement.
For ease of use, the ZM supports on‑demand grinding (adjustable grinding time) and allows you to save up to 20 grind settings (with custom names) plus 4 quick-recall buttons for your most-used recipes.
Built with a robust die-cast aluminium body and a double safety switch, the ZM combines industrial strength with barista-friendly precision—all in a dependable, premium package.
