Specs
| Zero | The burrs rub near 0.5 by design, so zero is the point where they still only just turn. Mavo advises not going below 2 8:47 10:20 |
Starting settings
There's no filter number yet. Light-roast espresso meant going below 2, against the maker's advice, and each tick moved the shot by about 8 s 10:20.
| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Espresso | slightly finer than the maker's suggested espresso range | Light-roast espresso. 60 to 70 s of hard grinding, with the burrs rubbing and getting warm | approx | DGC | 9:49 |
| Espresso | below the two setting | Needed for light-roast espresso despite Mavo's advice. Each tick changed the shot time by about 8 s on a flat profile | approx | DGC | 10:20 |

Cup profile

Strengths
- Grinds filter quickly, at 15 to 20 s for 15 g 2:03.
Weaknesses
Verdict
2025: a competitive filter grinder at $150, but not one for espresso 0:00.
The Coffee Chronicler's take
- 2025: a light-roast specialist with external steps of 16.6 µm, quick grinding and the whole range inside one turn. It's softer than other heptagonal grinders and great for modern espresso and filter, but thin for traditional shots. Along with the Millab M01, it's his top pick for modern espresso 20:29.
