| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Espresso | about 4 to 6 dots coarser than a setting that choked | 18.1 g of a light-medium washed coffee, 36 g out on a Decent with a Cremina-style lever profile. There's no absolute number to give | approx | Quan | 9:09 |
Cup profile
- Big body, chocolatey and textured like a Niche, with a little more clarity and body than the 63 mm Niche. It favours sweetness over acidity, so it mutes light roasts 0:30.
Strengths
- Easy to turn, even with light roasts. Retention is 0.1 to 0.3 g, there's no static, and it's quiet and portable with a magnetic cup. It forgives rough puck prep 0:30.
Weaknesses
- The unnumbered dial costs you a shot or two when dialling in, and the grounds can clump in the cup. Filter is poor, with lots of fines. It weighs about 1.8 kg and costs $750 to 800 0:30.
Verdict
In 2021 Brian Quan named it his best hand grinder for espresso, for how easy it is to use and its big-burr results. Dialling in is the main pain 0:30.
