Fellow · Conical burrOpus Conical Burr Grinder
Fellow's all-purpose entry grinder with 40mm C6-40 conical burrs, 41 stepped settings plus inner-ring micro-adjustment, and anti-static tech — a genuine espresso-to-cold-brew single-doser at a price most people will actually pay.
The short version
The Opus does what very few sub-$200 grinders credibly claim to do: it covers espresso through cold brew without asking you to swap burrs or buy a second machine.
The catch is an all-plastic body and stepped coarse intervals that demand the awkward inner-ring workaround any time you want real espresso precision.
Why people buy it
- Covers the full grind range — Turkish to cold brew — from a single machine at an entry price
- Anti-static design plus magnetic catch cup make for a notably tidier workflow than most rivals at this price
Why they don’t
- All-plastic housing scratches visibly over time and feels less durable than aluminum-bodied rivals
The full tally
- Covers the full grind range — Turkish to cold brew — from a single machine at an entry price
- Anti-static design plus magnetic catch cup make for a notably tidier workflow than most rivals at this price
- Grind guide printed inside the hopper lid reduces new-user friction considerably
- Compact footprint at 8.25 x 5 x 10.5 inches fits under most kitchen cabinets
- All-plastic housing scratches visibly over time and feels less durable than aluminum-bodied rivals
- Primary stepped dial has coarse intervals; espresso precision requires an internal micro-adjustment ring that is fiddly to access
- 40mm burrs and modest RPM mean grind speed lags behind larger-burred or higher-RPM competitors

Worth knowing before you buy — Most owners who outgrow it wish they'd saved the $260 toward the grinder ceiling — the Opus teaches good technique but rewards upgrade to flat-burr or espresso-capable conical platforms within 18 months of heavy use.
Known weak points — Static retention in hopper causing clumping; plastic body degradation over years of use; occasional adjustment ring stiffness complaints.
“Espresso brewed with Fellow Opus grinds tastes clean and bright. There are more than enough grind settings for coffee enthusiasts to brew different kinds of coffee, as well as dialing in espresso.”
“I like the Opus because it's quiet, looks amazing and I don't mind the more complicated inner adjustment ring.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who get serious about espresso typically outgrow the inner-ring workaround and move to a dedicated espresso grinder such as the DF54, Niche Zero, or Eureka Mignon range. Those who prioritize filter output over espresso often upgrade to the Fellow Ode Gen 2. Fellow's own Opus 2 (2025, 48mm burrs, stepless dial) is the direct successor for those who want to stay in the ecosystem.

- Grinder cleaning kit — Brushes and grinder tablets keep retention and stale grounds in check.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs pull syrup — naturals and classic medium roasts play straight into their character.

Common questions
Can the Fellow Opus grind fine enough for espresso?
Yes. The Opus reaches below 200 microns at its finest setting, which covers true espresso. Dialing in precisely requires using the internal micro-adjustment ring in addition to the main numbered dial, which takes some practice.
Is the Fellow Opus a single-dose grinder?
Yes — the load bin is designed for single dosing, and an internal impeller helps clear grounds from the chute, keeping retention low.
What catch cups are included?
The Opus ships with a magnetic grounds cup for brewed coffee and a spouted portafilter dosing cup compatible with 54mm and 58mm portafilters.
How does the Opus differ from the Fellow Ode Gen 2?
The Ode Gen 2 uses 64mm flat burrs and is optimized for filter coffee only — it cannot reach espresso fineness. The Opus uses 40mm conical burrs and covers espresso through cold brew, at a lower price, in an all-plastic body.
Is there an Opus 2?
Yes. The Opus 2 was announced in 2025 with 48mm conical burrs and a stepless side dial replacing the stepped dial and inner ring. It is a distinct, successor model at a higher price.
