Set a Fellow Opus between 3 and 6 for V60 pour over, per Honest Coffee Guide's compiled Opus chart; the full pour over window runs 3 to 8.5. Start at 4.5 and move half a number at a time: coarser if the cup is bitter, finer if it is sour or weak.
Fellow Opus grind settings by brew method
| Brew method | Fellow Opus setting |
|---|---|
| Espresso | 1 to 2.5 on the outer ring (the inner ring adds the fine sub-steps for dialing) [1] |
| Pour over | 3 to 8.5 (V60 at 3 to 6) [1] |
| AeroPress | 2 to 8.75 [1] |
| Moka pot | 2.5 to 5.5 [1] |
| French press | 6 to 11 [1] |
| Cold brew | 7.25 to 11 [1] |
Every numbered range above was checked against the source in the footnote it carries; where a manufacturer publishes nothing for a method, the row says so instead of inventing a number. Ranges are windows, not verdicts. Beans, roast age, and dose move the right setting inside each window, which is why the dial-in ladder below matters more than any single number.
How the Fellow Opus adjustment works
The Fellow Opus uses an outer ring numbered 1 (fine) to 11 (coarse) with marks between the numbers, plus an inner ring under the hopper that adds finer sub-steps for espresso work; Honest Coffee Guide charts the outer-ring range at 230 to 1160 microns. Find your zero before trusting any chart: with the hopper empty, tighten toward fine until the burrs just touch, call that zero, and count from there. If your zero point is calibrated differently from the chart's, every range shifts by the difference, which explains most "the chart is wrong" complaints.
Dial it in from the chart in 3 steps
1. Set the middle of the pour over range above and brew once, changing nothing else. 2. Taste against the two failure directions: sour, thin, or fast means grind finer; bitter, harsh, or stalled means grind coarser. The full logic lives in why espresso runs sour and why it runs bitter. 3. Move in small steps, one variable at a time, and write each attempt down; the free dial-in logbook exists for exactly this, and the printable dial-in cheat sheet keeps the correction table next to the machine.
The espresso question
Unlike its Ode sibling, the Opus is built to reach espresso: Fellow ships it as an all-method grinder and the 1 to 2.5 band plus the inner ring is real, usable espresso territory. It is the Fellow to buy if shots are in the plan; the Ode Gen 2 chart explains why the Ode is not.
