Fellow · Conical burrOpus 2
Fellow's second-generation all-purpose conical grinder, now with bigger 48mm burrs, a stepless dial, and a genuinely quick espresso grind. Built to be the one grinder in the house that covers everyone's cup.
The short version
This is Fellow fixing the original Opus's homework: bigger burrs, a stepless dial instead of the fussy dual-ring system, and a shot that grinds in about 9 seconds instead of a minute and a half.
Accept that it is still a plastic-bodied, single-dose-capacity grinder chasing a do-everything brief, not a dedicated espresso weapon for someone chasing SSP-level clarity.
Why people buy it
- Big jump from 40mm to 48mm conical burrs meaningfully speeds up espresso grinding (about 9 seconds a shot vs over 90 on the original)
- Stepless adjustment replaces the original's confusing dual-ring micro-adjust system
Why they don’t
- Still an all-plastic housing and catch cup, so it will not feel or wear like Fellow's metal-bodied Ode line
The full tally
- Big jump from 40mm to 48mm conical burrs meaningfully speeds up espresso grinding (about 9 seconds a shot vs over 90 on the original)
- Stepless adjustment replaces the original's confusing dual-ring micro-adjust system
- Genuinely covers the full range from espresso to cold brew with one grinder and one grind guide
- Two dedicated catch cups (brew and espresso, the latter fitting 54mm and 58mm portafilters) plus a strong anti-static ionizer keep workflow clean
- Still an all-plastic housing and catch cup, so it will not feel or wear like Fellow's metal-bodied Ode line
- 110g hopper is sized for single-dose or daily-bag use, not a always-full bean hopper for a busy household
- A do-it-all conical will not match a dedicated single-dose flat-burr grinder's clarity or consistency ceiling for serious espresso dialing
What the community knows
Years of owner threads, distilled — well regarded.
Delivers consistent espresso grinds and near-silent operation at an accessible price point, but the conical burr plateau and proprietary build limit long-term tinkering and ceiling — community consensus is "good for learning, expect to replace it within 3-5 years."

Worth knowing before you buy — Most owners say "get it, use it for a year or two, then upgrade to a burr grinder with real adjustability and parts ecosystem" — it is less a destination and more a confident on-ramp.
Known weak points — Macro/micro adjustment rings reported finicky and prone to drift; conical burr wear accelerates with high-volume use — no widely documented catastrophic failures but longevity concerns noted.

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who get serious about straight espresso typically outgrow the Opus 2 toward a dedicated single-dose flat-burr grinder (DF64-class or higher) for more consistent fines and a true stepless espresso-only workflow; filter-only households sometimes move sideways to Fellow's own Ode Gen 2 instead.

Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.

- Dosing cup — Pairs with single-dose grinding — grind into the cup, swirl, and transfer to the portafilter cleanly.
- 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 2 grind for espresso?
Yes. It is built to handle the full range from espresso to cold brew, includes a dedicated espresso dosing cup that fits 54mm and 58mm portafilters, and uses 48mm conical burrs engineered for a fine, consistent espresso grind.
How is the Opus 2 different from the original Opus?
The Opus 2 steps up to larger 48mm conical burrs (from 40mm), grinds an espresso shot in about 9 seconds versus over 90 seconds on the original, replaces the fiddly dual-ring adjustment with a single stepless dial, and adds an upgraded ionizer plus two dedicated catch cups.
Does the Opus 2 work for pour-over and cold brew too?
Yes, it is positioned as a one-grinder-for-everything machine covering espresso, pour-over, drip, AeroPress, French press, and cold brew, with a printed grind guide on the hopper lid as a starting reference.
