Mazzer Robur S Electronic for High-Volume Espresso
The Robur S is a 71mm conical-burr commercial grinder built for bars where the primary espresso grinder must keep moving through a sustained queue. Its low-speed burr drive emphasizes torque rather than very high RPM, while programmable electronic dosing sends coffee directly into the portafilter.
Mazzer redesigned the chamber and outlet to reduce retained grounds compared with the earlier Robur E. The manufacturer reports a 52% reduction in retention. That matters in a busy bar because less coffee remains behind between adjustments, and the chute is easier to clear during routine maintenance.
Why Cafés Choose the Robur S
- 71mm conical steel burrs: Intended for high-output espresso with a full-bodied cup profile.
- Grind Flow Control: A removable outlet insert and interchangeable wire dampers manage clumping, static and grounds flow.
- Three programmable doses: Save common recipes and activate them from the front controls.
- Barista pause: A programmed break can interrupt a dose for distribution before grinding resumes.
- Dual cooling: One fan supports motor cooling and a second fan continues briefly after a dose to manage internal heat.
- Service-oriented chamber: The lower burr carrier moves for adjustment and access while the upper carrier remains fixed.
GFC and Grounds Delivery
The Grind Flow Control system sits in the outlet path. Different damper configurations change how coffee exits, helping a technician or barista tune the balance between clump control, spray and speed for a particular roast and environment. The included general-purpose damper is the practical starting point; optional alternatives should be selected only when the shop has a specific flow problem to solve.

Best-Fit Café Workflow
This grinder is most compelling as a primary espresso grinder in a high-volume shop using one coffee for long stretches. Its large hopper and conical burr set are not optimized for frequent bean switching. A shop serving regular and decaf should normally plan for a second grinder rather than repeatedly emptying the Robur.
Keep the chute and GFC insert clean, check timed-dose output with a scale throughout the day, and make small stepless corrections as coffee ages. When moving significantly finer, run the motor during adjustment to reduce the chance of binding beans between the burrs.
Frequently Asked Questions
Does the Robur S grind by weight?
No. This electronic version uses programmable dosing rather than an integrated gravimetric scale.
What does 52% lower retention mean?
It is Mazzer’s comparison with the preceding Robur E chamber design, not a claim of zero retention.
Is this a home grinder?
It can operate in a home, but its size, hopper, power and workflow are intended for high-volume commercial service.
Does it include cooling fans?
Yes. The Robur S uses two fans to manage motor and chamber temperature during repeated grinding.

Mazzer Robur S Electronic Espresso Grinder Black: buyer guide, comparison and FAQs
The Robur S Electronic is a high-capacity commercial grinder for bars that deliberately want a large conical-burr espresso platform. It should be selected because the shop’s coffee program and peak service justify it, not simply because it sits at the top of a range.
Three checks before ordering
- Model the busiest continuous run of orders and decide whether the grinder removes a real queue bottleneck.
- Verify overall height, loaded weight, power and bar access before cabinetry is complete.
- Plan burr inspection, hopper cleaning and backup coverage as operating costs, not optional extras.
How this model compares
The Major V is the strongest alternative when a high-output flat-burr workflow is preferred. The Super Jolly V Pro can be the better-sized purchase for moderate commercial demand and a smaller investment.

Mazzer Robur S Electronic Espresso Grinder Black FAQs
Who should buy the Robur S Electronic?
A high-volume espresso bar that values its conical-burr workflow, has suitable space and power, and can support commercial cleaning and service.
How should it be compared with the Major V?
Compare cup goals, burr format, rush performance, retention management, footprint, service access and total ownership cost.
Is it automatically better for a small café?
No. Oversizing can consume budget and counter space without improving the drink. The right grinder meets peak demand with sensible headroom.
What should be verified before installation?
Confirm electrical supply, dimensions, loaded counter capacity, hopper-removal clearance, warranty and access to qualified service.
How can an electronic dose remain consistent?
Check output on a scale, keep the grounds path clean, adjust for coffee changes and document programming so all shifts use the same target.
