Mazzer Robur S Espresso Grinder

Mazzer Robur S: The New Standard for High-Volume Espresso

The Mazzer Robur S is the industry-leading workhorse, engineered specifically for the most demanding, high-volume coffee shops. It's the preferred choice for busy baristas because it delivers an unrivaled combination of speed, consistency, and intelligent design right when the pressure is on.

As Mazzer's fastest grinder, the Robur S outputs an incredible 6 grams per second, ensuring your bar never skips a beat. But speed is just the beginning. This grinder combines its high-performance output with exceptional dose consistency, a groundbreaking 52% reduction in retention, and advanced electronic controls, making it the definitive tool for any professional espresso bar.

High-Performance Grinding

At its core, the Robur S is built for power and precision. It features massive 71mm conical burrs, 100% Made in Italy by Mazzer, which are designed for high throughput and a uniform particle distribution. This is the engine that delivers its impressive 6g/second grinding speed, allowing you to serve customers faster during peak hours.

Advanced Thermal Stability

Grinding at high speeds generates heat, which is the enemy of consistent espresso. The Robur S is intelligently designed to combat this with a dual-fan cooling system and a low-speed, high-torque motor (running at 420-500 RPM). This system actively dissipates heat, protecting your coffee's delicate aromatics and ensuring your grind setting remains stable from the first shot of the morning to the last.

Industry-Leading Low Retention

The Robur S introduces a re-engineered grinding chamber that achieves an incredible 52% reduction in retained coffee compared to previous models. This is a game-changer for a busy café. It means less coffee waste from purging, fresher grounds for every shot, and significant cost savings over time.

Precision Workflow & Control

The Robur S is packed with smart, barista-focused features to perfect your workflow:

• Grind Flow Control (GFC) System: This system features a removable aluminum outlet insert with three interchangeable wire dampers (Hybrid, Anti-Clumping, Anti-Dust). It reduces static, eliminates clumping, and delivers a fluffy, perfectly centered dose in your portafilter every time, keeping your counter clean.
• Easy-Clean Grinding Chamber: The Robur S is designed for easy maintenance. You can access the grinding chamber for a full cleaning without losing your grind setting—a critical time-saver for daily operations.
• Memory Track System: A new, user-friendly indexing system for the stepless micrometric adjustment provides a wider, more precise grinding range and makes it simple to note and return to your favorite settings.
• Hands-Free Operation: An adjustable portafilter holder and an on-demand grinding function (activated by the portafilter) create a faster, more efficient, hands-free workflow.
• Smart Features: The grinder includes a magnetic tag holder for the hopper, so you can easily label the coffee you're using.

Advanced Electronics & IoT Connectivity

The Robur S features a robust electronic platform with three programmable, time-based doses. It also comes pre-set for IoT connectivity, allowing you to connect to the cloud to monitor grinder performance, track usage, and manage maintenance data in real-time
