Fellow Opus Conical Burr Grinder Review

Why a Burr Grinder Matters

Burr grinders crush beans to a consistent size, which is the biggest single improvement most home brewers can make. Blade grinders produce a mix of dust and chunks that brews unevenly, tasting bitter and sour at once.

The Opus sits above entry-level burr grinders like the Baratza Encore in features and below dedicated espresso grinders in price.

Range: From Espresso to Cold Brew

Fellow designed the Opus to cover the full range. Its 41 settings, plus the inner ring for finer calibration, make switching between pour-over and French press easy. The markings on the top dial map out where each brew method sits.

For drip, pour-over, AeroPress and French press, independent reviewers rate the grind consistency well for the price.

Espresso: Capable but Not Precise

The Opus can grind fine enough for espresso, but steps between settings are larger than on stepless or espresso-focused grinders. Dialing in a shot means using the inner ring, which adds friction to switching between methods.

If espresso is your main drink, a dedicated espresso grinder gives finer control. The Opus suits people who make espresso occasionally and filter coffee most days.

Design and Ownership

The single-dose approach suits people who weigh beans for each brew. Anti-static design and a magnetic catch cup reduce mess, though some static is typical in dry climates; a few drops of water on the beans before grinding helps any grinder.

Burrs wear slowly over years of use. Fellow sells replacement parts, and cleaning the burrs periodically with a brush keeps grind quality consistent.
