Mazzer Mini G GbW compact weight-based grinder for espresso
The Mazzer Mini G GbW Black is a compact espresso grinder with 64 mm flat steel burrs that incorporates Grind-by-Weight technology to dose coffee directly by weight, with a claimed accuracy of up to approximately ±0.1 g per dose. Designed as a ‘light commercial’ coffee grinder that can also be used in the home, it combines a motor of approximately 350 W with continuous micrometric adjustment and an indicative grinding speed of approximately 2–2.5 g/s, depending on the grind size and the coffee used. The control panel allows you to programme three doses (by weight or by time) in addition to manual mode, whilst the load cell and internal weighing system enable a fast and repeatable workflow, with very low retention and grinding settings that remain stable over time
What is the Mazzer Mini G GbW Black
The Mazzer Mini G GbW Black is a weight-based espresso grinder with 64 mm flat burrs, designed as a compact ‘light commercial’ coffee grinder suitable for both small establishments and advanced home baristas. It features an internal scale and a Grind-by-Weight system that allow coffee to be measured directly in grams, maintaining consistent doses and reducing waste compared to traditional time-based grinders
Key features of the weight-based grinder
The Mazzer Mini G GbW Black offers three programmable doses by weight or time, as well as a manual mode, controlled via a simple and intuitive front panel. The integrated load cell, combined with continuous micrometric adjustment, allows for precise operation even with repeated doses, with a retention rate that independent tests indicate to be around 0.1 g per cycle. The combination of 64 mm steel burrs, a motor of approximately 300–350 W and a rotation speed of around 1,400–1,600 rpm allows for grinding fast enough for espresso use, whilst maintaining a consistent grind profile and a workflow suitable for those preparing several coffees in succession.

Grind-by-Weight and coffee grinder with integrated scale
The Grind-by-Weight technology of the Mazzer Mini G GbW Black is based on an integrated scale that weighs the coffee during grinding and stops the grind when the set weight is reached. In this way, the user sets the desired grams directly (for example, 18 g) and the coffee grinder with scale automatically adjusts the cycle, ensuring doses very close to the target without the need for external weighing. For those looking for a weight-based grinder to pair with a domestic espresso machine or a small professional machine, this solution reduces the need for constant adjustments and makes it easier to maintain precise recipes over time.

FAQs about the Mazzer Mini G GbW
Is the Mazzer Mini G GbW suitable for home use or professional use only?
The Mazzer Mini G GbW Black is a weight-based grinder designed as a ‘light commercial’ machine: it was created for small establishments but is also very well suited to advanced home use, thanks to its compact size and Grind-by-Weight system, which simplifies the workflow.
What advantages does the weight-controlled grinder offer compared to a traditional Mazzer Mini?
Compared to an on-demand Mazzer Mini, the Mazzer Mini G GbW Black features an internal scale and Grind-by-Weight firmware, allowing you to set the desired grams directly, maintaining doses very close to the target and reducing the waste and micro-adjustments typical of time-only grinders.
Can the Mazzer Mini G GbW also function as a coffee grinder with a scale for single dosing?
The Mazzer Mini G GbW is primarily designed as a coffee grinder with a scale for use with a full hopper, but the low retention and precision of the Grind-by-Weight system also allow for single-dose use, with performance rated as good in independent tests.
