Single dosing on the Mazzer Mini

The Mini is the compact end of Mazzer’s flat burr range: 64 mm burrs, stepless adjustment, and a bean hopper holding roughly 600 g. It was designed as a small-cafe and home on-demand grinder, and a great many have ended up on home espresso benches.

Used the way it was designed, the hopper stays full and the grinder works through it. Used the way most people now run it — one weighed dose at a time, changing beans every bag — that hopper is 600 g of capacity you do not want and a reason for beans to sit going stale.

What the bellows actually does

The Mini uses horizontally mounted burrs with a conventional chute, so grounds do settle between doses. This hopper replaces the stock one: weigh a dose in, grind, then press the silicone bellows so the air pushes what is left in the chamber and chute down into your portafilter instead of into the next shot.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

How it is made

• 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
• Factory machine moulded: silicone bellows

Materials

• Lid, lock ring, connector: PETG hard plastic
• Air-leak prevention gasket: TPU — material info
• Bellows: factory moulded silicone

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
