Grind setting conversion
Fellow Ode Gen 2 vs Fellow Opus
Brew-only against all-purpose, from the same maker.
| Ode Gen 2 | Opus | |
|---|---|---|
| Brand | Fellow | Fellow |
| Scale | Numbered dial | Numbered dial |
| Dial range | 1 – 11 | 1 – 41 |
| Burrs | Flat | Conical |
| Espresso → filter | 4 numbers | 13 numbers |
| Filter → coarse | 6 numbers | 20 numbers |
The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 6 sits at grind index 50 on the Ode Gen 2 but 15 on the Opus — far enough apart to change the cup.
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.

| Drip / batch brew | 6 | 18.1 |
| Chemex | 6.8 | 20.3 |
| French press | 8.2 | 24.7 |
| Cold brew | 9.8 | 30.5 |
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.

Dialing in the Ode Gen 2
A flat-burr brew grinder that deliberately does not attempt espresso, and is better for the focus. The Gen 2 burrs cut fines substantially versus the original, which is why its filter range sits in a narrower band than the number of settings suggests. The markings between whole numbers are real and worth using — most of the useful pour-over territory lives between two adjacent integers.
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.
