Acaia Orbit Single Dose Coffee Grinder - Mazzer 0033M Burrs

The Acaia Orbit Mazzer 0033M is a premium single-dose electric coffee grinder designed for serious home brewers and light commercial use. Built around 64mm flat steel burrs, stepless adjustment, and app-enabled RPM control, it is made to deliver precise, repeatable grinding with a polished, low-retention workflow.

This version pairs the Orbit platform with Mazzer 33M burrs, offering a flavour profile well suited to classic espresso styles while remaining versatile enough for modern lighter roasts and balanced filter brewing. With automatic purge cleaning, Lunar grind-by-weight compatibility, and a refined aluminium-led build, it brings together advanced control, thoughtful usability, and a compact footprint.
