Fellow Opus 2

In this fellow opus 2 review, the Fellow Opus 2 is the stepless conical burr grinder to buy if you brew espresso, pour-over and cold brew on the same counter. The Opus 2 sits at number 8 of 9 in our 2026 espresso grinder guide, where it carries the label best stepless grinder for multi-brew setups. The numbers: $199.95, 4.3 stars from 38 Amazon ratings, 48 mm conical burrs, and a compact 7.95 by 5.12 by 10.49 inch body in black stainless steel. Fellow builds the Opus 2 for one job, grinding coffee, with a single dial that slides between espresso fine and cold brew coarse instead of clicking into fixed steps.

On the counter, the stepless dial is the feature that changes your routine. Because it moves continuously, you can nudge the setting a hair finer when a shot runs fast, then turn it back for pour-over without hunting for a numbered click. On top of that, the 48 mm conical burrs grind evenly across that whole range, so the same grinder covers French press and cold brew. Retention is the other quiet win: Fellow designed it so that when you start with 22 grams, nearly all 22 grams land in the basket, which means yesterday's dark roast will not season today's light one. Anti-static technology keeps grounds from clinging to the chute or scattering, and auto stop ends the grind when the dose is done.

Value is where this grinder earns its place. Even so, at $199.95 it is not the cheapest option in the guide. By contrast, the Breville Smart Grinder Pro and the Baratza Encore ESP lean on stepped settings, which is easier to repeat but harder to fine tune. Meanwhile, the Opus 2 trades that repeatability for range, and that is the honest trade-off: 38 Amazon ratings is the smallest sample in our ranking, so long-term reliability data is thin, and the dial has no numbers, so returning to yesterday's setting takes memory or a photo. If you brew three ways and want one dial that slides smoothly, the Fellow Opus 2 is the one to get.
