Head-to-head
Miicoffee DC63 vs Fellow Opus 2: Opus holds 100 g, DC63 stops at a 40 g single load

DC63 offers a removable chute and forty-gram single-dose capacity. Opus 2 adds a one-hundred-gram load bin and supplied catches for espresso and filter.
Before you choose
The reasoning and the trade-offs
A sixty-gram batch exceeds one DC63 load
Opus 2 can take that dose in one load, while DC63 needs the beans divided by its forty-gram published capacity.
What this is based on
60 g is greater than 40 g and below Opus 2’s 100 g load rating.

What matters in practice
The differences that matter
A sixty-gram batch exceeds one DC63 load
Opus 2 can take that dose in one load, while DC63 needs the beans divided by its forty-gram published capacity.
How we reached this conclusion
60 g is greater than 40 g and below Opus 2’s 100 g load rating.
Fellow’s capacity is two and a half times larger
That is useful for brew-batch planning, without implying it should hold beans between sessions like a storage hopper.
How we reached this conclusion
100 / 40 = 2.5 times the published load capacity.
The larger DC63 burr number does not decide the cup
Its sixty-three-millimeter conicals and Fellow’s forty-eight-millimeter set are specifications, not a substitute for matched taste evidence.
How we reached this conclusion
63 - 48 = 15 mm diameter difference, with no matched extraction or tasting test used.

Meaningful differences
What changes the fit
| What changes | MiiCoffee DC63 Single Dose Coffee Grinder | Fellow Opus 2 Conical Burr Grinder | Why it matters |
|---|---|---|---|
| Load capacity | 40 g with bellows | 100 g | Fellow supports larger batches in one load. |

| Chute maintenance | Magnetic detachable chute | Tool-free burr access | The access points differ. |
What you give up
Every choice has a cost
If you choose MiiCoffee DC63 Single Dose Coffee Grinder
- The proprietary 63 mm conical format offers fewer burr alternatives.
If you choose Fellow Opus 2 Conical Burr Grinder
- The lightweight body feels less substantial than metal grinders further up the range.
Recommendation switch
The decision flips if...
A sixty-gram drip-coffee dose in one load
Choose Fellow Opus 2 Conical Burr Grinder. Opus holds it in one load.
A detachable magnetic exit chute
Choose MiiCoffee DC63 Single Dose Coffee Grinder. DC63 provides that access.
A metal-bodied grinder preference
Choose MiiCoffee DC63 Single Dose Coffee Grinder. DC63 specifies aluminum construction.
Separate filter and espresso catch cups
Choose Fellow Opus 2 Conical Burr Grinder. Fellow supplies both formats.
What matters in practice
How to make the call
Capacity is the clearest batch-size distinction
DC63 holds forty grams with its bellows. Opus 2’s load bin and standard catch each hold one hundred grams. For a larger drip batch, the Fellow can avoid splitting the beans into multiple loads.
Both offer continuous adjustment and automatic stop
Those features are shared. The choice is more about grounds handling, construction and dose size than access to stepless adjustment.
The supplied cups target different transfers
Opus 2 includes a thirty-gram espresso catch compatible with 54- and 58-millimeter portafilters plus the larger standard catch. DC63 supplies a metal dosing cup and stand, with a detachable chute for cleaning.
