Single dosing on the Eureka Mignon

The Mignon is Eureka’s home and light-commercial line, and it is not one grinder. Burr size varies by model: the Silenzio, Crono and Perfetto use 50 mm flat burrs, while the Silenzio 55, Specialita and Mignon Zero use 55 mm. The two sizes are not interchangeable, which is worth knowing before you buy parts for one. A Specialita will put 18–20 g through in roughly 9–12 seconds.

Whichever model you have, the stock hopper holds far more than one dose. This v3.0 bellows hopper replaces it so you can weigh in a single dose, grind, then press the silicone bellows to push retained grounds through the chamber and out.

A grinder people already single dose on

The Mignon is one of the most common grinders in home espresso, and single dosing on it is normal practice — Eureka sell their own blow-up accessory for exactly this reason. If you are weighing every dose and changing beans often, keeping the stock hopper full works against you.

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.
