Mazzer Super Jolly g (Black)

Overview

The Mazzer Super Jolly g is a 64mm flat-burr commercial grinder engineered for medium-volume cafés that demand precision without compromise. Built around a professional load cell system, it delivers accurate weight-based dosing in any environment, remaining unaffected by counter vibrations or workflow fluctuations. With grinding speeds between 4 and 5.2 grams per second, a redesigned three-segment grinding chamber, and a powerful high-torque asynchronous motor, this grinder combines the reliability Mazzer is known for with meaningful performance upgrades. It arrives standard with 205D bearing steel burrs optimized for medium-dark roasts, with optional ZZ k206P tooling steel burrs available for lighter profiles.

Professional Load Cell & Vibration Filtering

The Super Jolly g incorporates a built-in load cell with Mazzer's Vibration Filtering Algorithm, which isolates the weighing platform from external interference. Commercial environments generate constant vibration from espresso machines, knockboxes, and foot traffic. Most grind-by-weight systems struggle in these conditions, producing inconsistent doses as the scale reacts to ambient movement. Mazzer's algorithm filters out these disturbances in real time, allowing the grinder to maintain accurate weight-based grinding regardless of what's happening around it. This means baristas don't need to compensate for drift or recalibrate throughout service, and dose consistency remains tight from the first shot of the morning to the last.

Enhanced Grinding Speed

Operating on the Super Jolly V Pro platform, the Super Jolly g delivers twice the grinding speed of its predecessor, reaching between 4 and 5.2 grams per second depending on grind setting and coffee density. This improvement comes from a newly designed three-segment grinding chamber that accelerates coffee exit while maintaining consistent particle flow and distribution. The chamber geometry prevents bridging and channeling, common issues that create uneven particle size and workflow bottlenecks. Mazzer pairs this chamber with a purpose-built high-torque asynchronous motor that matches the specific resistance characteristics of their 64mm burr set, eliminating the lag and inconsistency that result from underpowered motor-burr pairings.

Thermal Management & Dose Consistency

Grinder temperature directly affects dose accuracy and coffee flavor, particularly during high-volume periods when heat buildup becomes inevitable. The Super Jolly g addresses this with a dual-fan cooling system and redesigned grinding chamber that optimize airflow around the burrs and motor. This thermal management prevents the heat-induced expansion that causes grind setting drift and maintains stable chamber conditions even as grinding volume fluctuates throughout service. The result is consistent dosing from shot to shot and protection of volatile aromatics that degrade under excessive heat. Baristas can rely on the same grind quality during a mid-morning rush as they get during slower periods.

Grind Flow Control System

The Grind Flow Control system manages static electricity at the output stage, addressing the retention and mess issues that plague most commercial grinders. Static charges cause ground coffee to cling to internal surfaces, create clumping in the portafilter, and scatter onto the counter and work area. The GFC system includes two interchangeable dampers: Hybrid mode balances speed and cleanliness for standard workflow, while Antidust mode prioritizes maximum static reduction when working with particularly charged coffees or low-humidity environments. This system reduces cleaning time, minimizes coffee waste from retention, and improves the consistency of puck preparation by delivering grounds that distribute evenly rather than clumping on contact.

Hands-Free Operation

The Super Jolly g eliminates manual start buttons with Place-and-Grind activation, which automatically detects when a portafilter or dosing cup is positioned under the chute. An adjustable portafilter holder ensures grounds land centered in the basket regardless of portafilter size or design, reducing the need for redistribution. The included magnetic dosing cup accommodates up to 30 grams and aligns perfectly under the spout for single-dosing workflows or preparing doses in advance. When switching grind settings, the grinder automatically compensates for the new particle size, eliminating the typical routine of grinding, weighing, adjusting, and regrinding. Baristas simply dial in, place the portafilter, and get accurate doses immediately.

Standard 205D Burrs for Milk-Based Drinks

The Super Jolly g ships with 205D 64mm flat burrs made from bearing steel, designed specifically for medium-dark roast profiles common in high-volume espresso service. These burrs produce a particle distribution that emphasizes body and texture, delivering chocolate-forward flavor profiles with long aftertaste and substantial mouthfeel. This geometry excels in milk-based drinks, where clarity takes a back seat to structure and sweetness. The 205D set handles the oils and brittleness of darker roasts without loading or dulling prematurely, maintaining consistent particle size throughout their service life. For cafés built around traditional espresso and milk drinks, these burrs require no upgrade or modification.

Optional ZZ k206P Burrs for Light Roasts

Mazzer's ZZ k206P burrs represent their most advanced burr design, machined from specialized tooling steel that offers twice the lifespan of standard bearing steel. The k206P geometry features continuous, sharp teeth that gradually refine particles across the full cutting surface rather than concentrating force at entry points. This produces a different particle distribution optimized for light to medium roasts, where clarity and complexity matter more than body. The k206P delivers well-rounded cups with pronounced acidity, fruit-forward notes, and a softer, more delicate texture compared to the heavier profile of the 205D. The precision machining tolerances possible with tooling steel result in tighter particle consistency, particularly valuable when working with dense, light-roasted beans that challenge grinder performance.

Construction and Serviceability

Built primarily from stainless steel, aluminum, brass, and copper, the Super Jolly g prioritizes material quality over plastic components. This construction improves durability and thermal stability while making the grinder fully recyclable at end of life. The grinding chamber remains accessible for cleaning without disturbing grind settings, a critical feature for maintaining hygiene standards without sacrificing dial-in time. Mazzer designed the grinder for NSF compliance, meeting commercial health and safety standards for foodservice equipment. The adjustment collar includes a Memory Track ring for quick recalibration, and IoT connectivity enables remote monitoring of grind data and performance metrics. Firmware can be updated as Mazzer refines algorithms or adds features, extending the functional lifespan of the hardware.
