Overview

The Mazzer Mini G brings grind-by-weight precision to the compact footprint that made the original Mazzer Mini an icon in specialty coffee. This light commercial grinder is built for high-volume environments where counter space is at a premium—mobile carts, small cafés, or as a dedicated single-origin grinder in busier shops. It pairs a professional-grade load cell scale accurate to 0.01 grams with a grinding speed increase of over 50% compared to its predecessor, all housed in Mazzer's signature die-cast aluminum chassis. The result is a grinder that delivers commercial durability and dosing precision without demanding the footprint of a full-size production grinder.

Integrated Grind-by-Weight System

At the core of the Mini G is a professional load cell scale that measures output to hundredths of a gram, eliminating the guesswork and waste associated with time-based dosing. The system allows you to program three distinct doses—whether by weight or by time—and recalls them with single-button access. This precision extends beyond initial setup: the grinder includes load cell recalibration functionality to maintain accuracy as the scale experiences wear over thousands of cycles. In practice, this means consistent 18 gram doses whether you're on your first shot of the day or your two-hundredth, with minimal drift over the grinder's service life.

The grind-by-weight approach also incorporates what Mazzer calls a Vibration Filtering Algorithm, which compensates for motor vibration and environmental factors that can throw off less sophisticated scales. This is particularly valuable in mobile or high-traffic environments where the grinder may experience movement or counter vibration during operation.

Hands-Free Operation & Portafilter Centering

The Mini G features portafilter and dosing cup activation, allowing completely hands-free grinding once you've positioned your vessel. An adjustable portafilter fork accommodates different basket sizes and can be positioned to center the coffee stream precisely in the basket—a critical detail for achieving even puck density and consistent extractions. The fork's adjustability means you can optimize flow for everything from a standard 58mm double basket to smaller single-dose cups, ensuring the grounds land where you want them regardless of vessel geometry.

This hands-free workflow proves especially valuable during service rushes, when a barista can stage a portafilter, initiate grinding, and turn attention to steaming milk or other tasks while the grinder completes its programmed dose. The system's repeatability means less time spent checking doses on a separate scale and more confidence in shot-to-shot consistency.

64mm Flat Steel Burrs

The Mini G employs 64mm flat steel burrs—a size that represents the lower threshold of what's typically considered appropriate for commercial espresso service, but more than adequate for moderate-volume environments. These burrs spin at 1400 RPM on 50Hz power or 1600 RPM on standard North American 60Hz current, striking a balance between grinding speed and heat generation. The 350-watt motor drives these burrs with enough authority to handle back-to-back grinding without bogging down, while the grinder's improved speed over previous Mini models means you're spending less time waiting for doses to complete.

Grinding Performance

Grind adjustment is stepless, giving you infinite control over particle size without the limitations of clicked detents. This is particularly useful when dialing in lighter roasts that may require finer adjustments to hit extraction targets, or when switching between espresso and alternative brew methods using the same grinder.

Antistatic Design & Retention Management

Coffee grinders generate static electricity during grinding, which causes fine particles to cling to surfaces and float into the air. The Mini G addresses this with an integrated antistatic system designed to deliver grounds with minimal static charge, keeping them flowing cleanly into the portafilter rather than sticking to the chute or creating a mess on the counter. While no system completely eliminates static—especially in low-humidity environments—the Mini G's approach reduces the need for frequent wipe-downs and the coffee waste associated with chaff and fines escaping the intended path.

Hopper Capacity

The grinder's relatively compact 280-gram hopper capacity actually works in favor of retention management. With less volume sitting in the hopper, coffee moves through the grinder more quickly, reducing stale-coffee issues in lower-volume settings. This capacity is appropriate for a grinder that's either handling moderate daily volume or serving as a dedicated secondary grinder for a specific coffee or preparation style.

Maintenance Intelligence & Interface

The Mini G's display does more than show dosing information—it actively monitors grinder health and alerts you to service needs before they become problems. The system tracks burr wear and will notify you when replacement is due, monitors hopper level to prevent empty-hopper grinding, and flags when routine maintenance intervals arrive. This proactive approach to service means less downtime and more predictable maintenance scheduling, particularly valuable in commercial settings where grinder failure during service can cascade into significant operational problems.

The interface itself is customizable, allowing you to select color themes to match your bar aesthetic or personal preference. While this might seem superficial, interface legibility and user comfort matter in high-stress service environments, and the ability to adjust display characteristics means the grinder can adapt to different lighting conditions or user preferences. All of this intelligence sits behind a straightforward control scheme that doesn't require extensive training—critical for environments with multiple staff members or high turnover.
