Overview
The Mazzer Robur is the flagship conical burr grinder from Italy most storied grinder manufacturer. Massive 71mm conical burrs spinning at low RPM produce a rich, full-bodied grind profile that excels in espresso. The powerful 600W motor can handle the highest-volume café environments without breaking a sweat. While primarily a commercial unit, some dedicated home users adopt the Robur for its exceptional grind quality and near-indestructible build. The conical burrs produce a different flavor profile than flat burrs — more body, more sweetness, slightly less clarity — making the Robur the preferred choice for shops focusing on traditional espresso and milk drinks. A monument of Italian coffee engineering.
The Mazzer Robur features a 71mm conical burr set, crafted from steel. The burrs spin at 400 RPM, a deliberately slow speed that minimizes heat buildup and preserves coffee aromatics. Grind retention is approximately 3.0g, typical for a hopper-fed workflow.
At $2,200, the Mazzer Robur is aimed at uncompromising enthusiasts and professionals who want the absolute best. Key workflow features include stepless grind adjustment for infinite precision. The conical burr design is known for producing a slightly bimodal grind distribution, which many enjoy for its body and complexity in espresso.
The Mazzer Robur is weighing 21.0 kg, manufactured in Italy, powered by a 600W motor. Its footprint measures 240 x 310 x 640 mm (W×D×H).
