In short
The Fellow Opus 2 is a grinder with 48mm conical burrs and stepped adjustment, typically $195–$245. It suits one grinder for every brew method and small kitchens. It is the wrong choice for espresso-first setups and light-roast espresso.
How it fits
Preinfuse ratings, not measurements. Each one is produced by published rules from the specifications below — open any row to see which facts moved it.
What it does well
- 48mm conical burrs and a single-dose bin at an entry price.
- Only 5.1 inches deep — the smallest counter footprint of any electric grinder here.
- Genuinely covers espresso through cold brew, so it can be the only grinder in the kitchen.
- Two-year warranty, longer than most at this price.
- Looks like something you leave out, which for a lot of kitchens decides the purchase.
Where it gives ground
- 48 settings spread across every brew method leaves relatively few inside the espresso range.
- Fellow's own page describes both a 'stepless adjustment dial' and a fixed 48 settings; we record the 48 settings as the practical resolution and flag the wording as inconsistent.
- Better suited to filter than to demanding espresso.
- No published motor or RPM figures.
Buy it for

Living with it
Weigh beans into the load bin, set the dial, grind into the catch cup — a genuine single-dose workflow at this price.
Where people go next: DF54, Niche Zero.
Before you buy
If espresso is the main event, the Encore ESP or a DF54 puts more resolution where you need it.
If you make pour-over daily and espresso at weekends, this is the better buy.

Identity1
- Operation
- Electric
Hand grinders deliver burr quality far above their price because you supply the motor. The cost is roughly a minute of effort per shot, every shot.
Mains-powered grinder.
Burrs3
- Burr type
- Conical
- Burr diameter
- 48 mm
- Burr material
- Stainless steel
Flat burrs tend to produce a narrower particle distribution, which many people read as clarity and separation. Conical burrs are cheaper to make, run cooler and are often described as producing a heavier, more forgiving cup. Burr quality and alignment matter more than shape.
Larger burrs cut more coffee per rotation, so they grind faster and run cooler. Diameter is a rough proxy for grinder class, not a quality score on its own.
Hardened steel is the norm and holds an edge for years of home use. Ceramic stays sharp longer but is more brittle; coatings mainly extend life.
Adjustment4

- Yes
Espresso is sensitive to very small grind changes. Stepless adjustment lets you land between two settings, which is the difference between a shot that runs in 25 seconds and one that runs in 40. Stepped grinders with fine enough steps are perfectly workable.
Recorded as stepped because Fellow publishes a fixed count of 48 settings.
The number of discrete positions available. On a stepped grinder this is the practical limit of your precision.
Whether the grinder actually reaches, and can be adjusted usefully within, the espresso range. Many well-regarded filter grinders cannot, and a grinder that only just reaches espresso leaves you no room to dial in.
Matters if this is your only grinder and you also make pour-over or French press.
Dosing & workflow2
- Dosing
- Single-dose
Single-dosing means weighing beans per shot: fresher, easy to switch coffees, more steps. A hopper is faster in the morning but leaves beans sitting in the open and makes changing beans a chore.
Practicalities4
- Height
- 10.5"
Height with the hopper fitted — the figure that decides whether it fits under a wall cabinet.

Why this, not the Encore ESP?
The Encore ESP is ahead on speed in the morning and being forgiving to learn on. If that is what matters to you, it is the better buy.
