Fellow Opus 2 Review: The Opus Finally Grinds Espresso

The Fellow Opus 2 is the first Opus you can genuinely recommend for espresso. The original looked great and ground a decent pour-over, but it could never dial in fine enough for a shot. The 2 fixes exactly that, with larger 48mm burrs and a stepless dial that moves in tiny increments, so espresso is finally on the menu.

I grind on a Mazzer Super Jolly at home, so I am not the target buyer for a compact electric like this. But the thing people ask about the original Opus was always the same: can it do espresso properly? For the first generation the honest answer was not really. The Opus 2 is built to change that, and I have gone through the spec and the way it is set up to tell you whether it does.

Is the Fellow Opus 2 good for espresso?

Yes, and that is the whole reason the 2 exists. The 48mm conical burrs and the stepless adjustment let you make the fine, continuous changes espresso needs, which is the exact thing the original Opus could not do with its fixed stepped settings.

Espresso lives or dies on small grind changes. A stepped grinder jumps between fixed points, and on the original Opus the right espresso setting often sat frustratingly between two steps. Stepless adjustment moves continuously, so you can nudge the grind finer or coarser by a hair to chase the right shot time. That single change is what moves this from a pour-over grinder that could sort-of do espresso to one you can actually dial a shot in on.

What changed from the original Opus

Two things matter: the burrs grew to 48mm, and the stepped dial became stepless. The larger conical burrs grind more evenly, and the stepless adjustment is what unlocks espresso.

The rest of the Opus DNA carries over, which was always the appealing part. It stays a compact, good-looking grinder that does not dominate a counter, and it keeps the all-rounder range that lets it grind for more than one brew method. The upgrades are aimed squarely at the one job the first model fell short on.

Retention and mess, the quality-of-life wins

Near-zero retention is a headline feature. Fellow says that when you start with 22 grams of beans, nearly all 22 grams make it out, so very little old coffee carries over into your next brew.

That matters more than it sounds. A grinder that holds onto grounds gives you stale carry-over and throws off your dose when you are weighing shots to the gram. Low retention keeps your dose honest and your coffee fresh. The anti-static technology is the other daily win, cutting down the grounds that cling and scatter across the counter, which is one of the genuine annoyances of grinding at home.

One grinder for more than one brew

The Opus 2 spans espresso, pour-over, French press and cold brew. If you make espresso in the morning and a pour-over in the afternoon, it covers both from one machine rather than needing a second grinder.

That versatility is the quiet argument for it. A lot of home setups end up with separate grinders for espresso and filter because one machine could not do both well. An electric that genuinely crosses the range, now including espresso, saves counter space and money for people who brew more than one way.

Who should buy the Fellow Opus 2

Buy it if you want one tidy electric grinder that handles espresso and everything else, with low retention and little mess, at a sensible home price. For a first real grinder, or to replace a hand grinder you are tired of cranking, it is a strong pick.

Skip it if you are chasing the last few percent of espresso grind quality, where a dedicated single-dose espresso grinder costing a good deal more will still pull ahead. This is the versatile all-rounder, not the specialist.

The honest limitations

Two things to keep in mind. It is a single-dose style grinder rather than a hopper machine, so you weigh in what you want to grind each time, and it is a second-generation product, so its long-term reliability is still being proven.

Neither should put off the buyer it is aimed at. Single-dosing is how most people grinding fresh for espresso work anyway, and the generational update is exactly what fixed the original's espresso weakness. Just go in knowing this is the versatile home grinder that now does espresso, not a commercial-grade espresso specialist.

What I'd buy today

If you want a good-looking electric grinder that finally does espresso as well as everything else, the Opus 2 is an easy one to recommend. Low retention and anti-static mess control are the quiet bonuses. Weigh in your beans, dial the stepless adjustment to your shot, and you have a single grinder covering your whole coffee week.
