Baratza Sette 270Wi vs Fellow Opus
Two grinders cross-shopped at the same money. The Opus is numbered 1–11; the Sette 270Wi is numbered 1–31.
Which to buy
Choose the
Sette 270Wi if you…
- want it to grind by weight — a built-in Acaia scale, to 0.1 g
- grind hands-free into a 49–58 mm portafilter
- swap beans often — the hopper has a shut-off
Choose the
Opus if you…
- brew French press or cold brew too — Fellow rates it from espresso to cold brew
- dose by time — auto-stop at 30, 60, 90 or 120 seconds
- want an inner ring for micro-adjustment between the 41 dial settings

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 4.9 on the Sette 270Wi but 34.2 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.

| French press | 25 | 9 |

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 Sette 270Wi
The Sette 270 with an integrated scale, grinding to weight rather than time. Same straight-through, near-zero-retention design and the same macro/micro adjustment — and the same considerable noise.
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.
