Specs
| Dial | A side wheel gives fine adjustment, but there are many turns between espresso and filter and no clear marker for where you are 1:33 |
Where sources disagree
The creators don't all give the same figure here, so every value is listed with the person who gave it.
| Field | Value | By | Source | Note |
|---|---|---|---|---|
| Burr size (mm) | 64 | Hoffmann | 1:33 | Sold as 65 mm, but James Hoffmann found 64 mm burrs fitted |
| Burr size (mm) | 65 | Rowsell | 5:07 | |
| Burr size (mm) | 65 | Rowsell | 13:15 | |
| Burr size (mm) | 65 | Sprometheus | 6:13 | Sold as the Mignon Single Dose |
| Burr size (mm) | summary | James Hoffmann found 64 mm burrs in a grinder sold as 65 mm. Kyle Rowsell and Sprometheus give 65 mm. It may be rounding or marketing. |

| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Espresso | about 3 to 3.5 turns from burr touch | His espresso range, roughly | unclear | Rowsell | 7:41 |
| Pour-over | about 1 to 1.5 turns from burr touch | His filter range, which changes with the coffee | unclear | Rowsell | 7:41 |
Cup profile
- The particle spread is very close to a DF64, and filter is fine 1:33 24:08.
- Lance Hedrick's sieve test found more fines than a DF64 16:27.
Strengths
- Solid build, and opening the burr chamber doesn't lose your setting 1:33.
Weaknesses
- It can't take other 64 mm burrs, and switching to filter is a chore 1:33.
Verdict
James Hoffmann called it a solid espresso-only option in 2023, let down by the lack of burr choice 1:33. Lance Hedrick gave it a C in 2024 10:00.
Kyle Rowsell's take
- 2022: a great cup, with textured, defined flat-burr espresso and filter cleaner than a Niche. Retention wasn't as low as promised. The clump crusher packed about 1.5 g so the bellows stopped working, and taking it out adds static. It's loud, and his grinder was misaligned at first, chirping at 9 instead of 0. SSP burrs wouldn't fit. $799 5:07.
- Against a DF64 it had more texture, sweetness and complexity but less clarity and worse retention, at about twice the price. He didn't think it was worth it 13:15.
Sprometheus's take
- 2022, sold in the US as the Mignon Single Dose: balanced, sweet espresso and crisp pour-over at 18 to 20% extraction, grinding about 3 g/s with fluffy grounds. Retention reached 0.5 g even with the bellows, it was louder than claimed, the multi-turn dial is small and there's no anti-popcorn disc. He doesn't see it as a Niche killer, more a solid flat-burr sibling for about $200 more 6:13.
