Grind setting conversion
Eureka Mignon Silenzio vs Fellow Opus
Conical against flat — the Opus's scale curves where the other runs straight. The Opus is numbered 1–11; the Mignon Silenzio turns 0–24 rotations.
| Mignon Silenzio | Opus | |
|---|---|---|
| Brand | Eureka | Fellow |
| Scale | Rotations | Numbered dial |
| Dial range | 0.0 rotations – 24.0 rotations | 1 – 11 |
| Burrs | Flat | Conical |
| Espresso → filter | 6.5 rotations | 3.3 numbers |
| Filter → coarse | 7 rotations | 5 numbers |
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

Side by side, by brew method
Where each grinder lands for the same brew, worked out from its own dial curve.
| Method | Mignon Silenzio | Opus |
|---|---|---|
| Espresso | 2.3 rotations | 1.9 |
| Moka pot | 3.9 rotations | 3 |
| AeroPress (short steep) | 5.5 rotations | 3.7 |
| Pour over — V60 / cone | 7.7 rotations | 4.4 |
| Pour over — flat bottom | 8.6 rotations | 4.8 |
| Drip / batch brew | 9.2 rotations | 5.2 |
| Chemex | 10.1 rotations | 5.8 |
| French press | 11.7 rotations | 6.9 |
| Cold brew | 13.6 rotations | 8.4 |
The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.
Eureka Mignon Silenzio
Fellow Opus
Dialing in the Mignon Silenzio
The Silenzio is the quieter Mignon, sharing the micrometric stepless adjustment that makes small movements meaningful at the fine end. Built for espresso; filter is possible at the far edge of the dial.
Dialing in the Opus
Marketed as all-purpose, and it genuinely does cover more range than the Ode, but the espresso end is workable rather than good — expect to chase it. Where it earns its place is the coarse end: cold brew and French press come out notably even. If you bought the Opus mainly for espresso, dial it as a brew grinder first and judge it there.
