Single dosing on the Mazzer Super Jolly

The Super Jolly has been a café standard for decades: 64 mm flat burrs turning at around 1600 rpm, stepless adjustment through a worm gear, and a bean hopper that depending on the variant holds anywhere from roughly 250 g on the short hopper to around 1.1 kg on the tall one.

Plenty of Super Jollys have since moved from cafés into home setups, where they get used one dose at a time. That is the workflow this hopper is built for. It takes the place of the stock bean hopper, so you weigh in a single dose, grind it, then press the silicone bellows to push retained grounds out of the burr chamber and chute.

Built for a grinder that outlives its first owner

Second-hand Super Jollys vary. Burr wear, chute condition and how previous owners treated the grinder all differ, and hoppers from different production runs do not always sit identically. Expect to make small adjustments to get a clean seat — see the fitting note below.

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.
