Fellow Opus pour over grind setting: the verified range

Fellow Opus pour over grind setting: the verified range

As an Amazon Associate, Barista Life earns from qualifying purchases.

Set a Fellow Opus between 3 and 8.5 for pour over, per Honest Coffee Guide's compiled Fellow Opus chart; inside that, a V60 cone wants the tighter 3 to 6 band. Start in the middle of the window and adjust on taste: finer if the brew drains fast and tastes sour, thin or weak, coarser if the bed stalls, the brew takes far longer than usual, or the cup tastes bitter.

Fellow Opus pour over settings, and the bands either side

What Setting on the Fellow Opus
Pour over window 3 to 8.5 [1]
V60 cone, the tighter band inside it 3 to 6 [1]
The AeroPress band on the same chart 2 to 8.75 [1]
The French press band on the same chart 6 to 11 [1]
Full grind range of the grinder 230 to 1160 microns [1]

The neighbouring bands are there for context. If your pour over sits at one end of its window and still tastes wrong, the answer is usually a different variable, not another step in the same direction, because past that edge you are grinding for a different brew method.

Why pour over wants this part of the dial

Pour over is percolation: water passes through the bed once, under gravity, and the grind sets how fast the bed drains. Drawdown time is the tell, and it is the number to watch before you argue with the taste.

Dial it in from the chart in 3 steps

1. Set the middle of the pour over window above and brew once, changing nothing else. 2. Taste against the two failure directions: finer if the brew drains fast and tastes sour, thin or weak, coarser if the bed stalls, the brew takes far longer than usual, or the cup tastes bitter. The full logic is in the pour over guide and the pour over ratio. For the rest of the recipe, see what to do when a pour over is too slow. 3. Move in small steps and write each attempt down; the free dial-in logbook exists for exactly this. Keep the pour pattern the same while you change grind. Pouring technique moves drawdown as much as a couple of settings do.

How the Fellow Opus adjustment reads

The Fellow Opus uses an outer ring numbered 1 at the fine end to 11 at the coarse end, plus an inner ring for finer steps. Find your zero before trusting any chart: with the hopper empty, close the burrs until they just touch, call that zero, and count from there. A zero point calibrated differently from the chart's shifts every range by the difference, which is behind most complaints that a chart is wrong. The full Fellow Opus grind settings chart has every other brew method on one page.
