Mazzer Robur Electronic S Black Coffee Grinder

Mazzer Robur S Electronic Coffee Grinder — Black — High-Performance Conical Burr Grinder for High-Volume Cafés

Overview

The Mazzer Robur S Electronic is a high-performance conical burr espresso grinder hand-built in Venice, Italy, much favoured by bartenders and baristas dealing with large daily volumes and demanding workloads. Equipped with 71mm conical burrs and an 800W motor, the Robur S delivers an average grinding speed of 1 second per 5g (50Hz) — making it the flagship workhorse of the Mazzer S line and the go-to choice for high-volume specialty cafés, busy roasteries, and venues where peak service hits hard and grind quality cannot be compromised.

The defining strength of the Robur S is its combination of consistent dosing, uniform coffee grounds, and significantly reduced retention — 52% less retention than previous generations means less wasted coffee and faster, more accurate dialling-in when changing settings. Low-RPM operation (420 rpm @ 50Hz) combined with a tailor-built double fan cooling system and split chassis design protects coffee beans from heat exposure across long grinding sessions, preserving aroma and in-cup quality through the busiest service. The Electronic version features a touch display configurable in 19 languages, with three programmable buttons for single, double, and triple doses (accurate to one hundredth of a second) plus a fourth manual button for precise fine tuning of the dose.

IoT connectivity is pre-set as standard — letting baristas, roasters, owners, and service technicians remotely access real-time grind reports via the cloud for monitoring output, tracking usage, and improving coffee quality through data-driven insights. The state-of-the-art Grind Flow Control (GFC) system reduces electrostatic charge and prevents clumping with a removable aluminium outlet insert and three interchangeable wire dampers (AntiClumping, AntiDust, and Hybrid) — letting baristas tune the grinder to coffee origin, roast profile, weather conditions, or personal preference. A user-friendly Memory Track system indexes grind settings, the wider, more precise grinding adjustment range gives baristas finer control, and a portafilter-activated grinding button on the fully adjustable portafilter holder enables hands-free workflow. For the operator running a serious high-volume coffee program who wants the best conical burr grinder Mazzer makes outside of the Kold S, the Robur S Electronic is the definitive choice.
