Mazzer Mini G Electronic GBW Coffee Grinder - Black

Mazzer Mini G Electronic GBW Coffee Grinder — Black — Compact Grind-by-Weight Espresso Grinder

Overview

The Mazzer Mini G unites the iconic design of the original Mazzer Mini with advanced grind-by-weight technology, delivering precise, repeatable dosing in a compact light-commercial footprint. Hand-built in Venice, Italy, the Mini G is purpose-built for small cafés, premium home espresso setups, offices, and roastery cupping benches that demand professional dosing accuracy without the size of a full commercial grinder.

At the heart of the Mini G is a professional built-in scale with load cell accuracy to one hundredth of a gram, paired with Mazzer's proprietary Vibration Filtering Algorithm (VFA) that maintains consistent ±0.1 g dose accuracy even when the bench is busy and vibrating. In grind-by-weight mode, the Mini G automatically maintains your set dose weight regardless of grind setting changes — eliminating wasted coffee and the need to manually reweigh after dialling in. A heavy-duty die-cast aluminium body houses a tailor-made 350W asynchronous motor delivering 2–2.5 g/s grinding speed through 64mm flat burrs, while a clear TFT display configurable in 19 languages keeps the barista in full control. Finished in matt black, the Mini G is a true everyday workhorse for the serious coffee operator.

Features

• Professional Built-in Scale with ±0.1g Accuracy — Load cell accurate to one hundredth of a gram delivers sharp, repeatable dose-by-weight performance on every shot.
• Vibration Filtering Algorithm (VFA) — Maintains consistent weight-based doses even during peak service when bench vibrations would compromise other scales.
• Automatic Dose Adjustment — In grind-by-weight mode, the Mini G holds your set dose weight regardless of grind size changes — no manual reweighing or recalibration required after dialling in.
• 3 Programmable Doses + Manual Mode — Programmable by weight or time with accuracy to the hundredth of a gram or second, plus a manual grinding mode for full barista control.
• 64mm Flat Burrs (233M Bearing Steel) — Mazzer's in-house designed and manufactured burrs deliver well-balanced extractions with rich body and velvety texture, particularly suited to milk-based drinks. Optional k202P special steel burrs available for sweet, delicate light-roast extractions.
• Magnetic Stainless Steel Dosing Cup — Self-aligning under the spout for hands-free grinding, with a 30g capacity and shape tailored to fit ø58mm portafilters. Included as standard.
• Portafilter or Dosing Cup Activation — Hands-free grinding triggered by either the portafilter holder or the dosing cup, giving baristas full workflow flexibility.
• Adjustable Portafilter Holder — Multi-adjustable holder centres the flow of grinds in the basket for cleaner workflow and reduced channelling.
• Antistatic System — Keeps the bench clean from coffee dust while delivering uniform, fluffy grounds.
• Easily Removable Chute — Pull-out grinding chute for fast, effortless cleaning between bean changes.
• TFT Display with 19 Languages — High-visibility display with excellent viewing angles, customisable colour theme, dose countdown, daily grinding statistics, and alerts for service needs, worn burrs, and empty hopper.
• Load Cell Recalibration — Built-in recalibration procedure ensures stable, accurate weighing performance over the life of the grinder.
• Stepless Micrometrical Grind Adjustment — Continuous micrometric adjustment for precise grind size control across espresso applications.
• Heavy-Duty Die-Cast Aluminium Body — Built for durability and longevity, with long-term spare parts support as standard from Mazzer.
• Hand-Built in Venice — Made in Italy, upholding Mazzer's tradition of in-house design and manufacturing since 1948.
