| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Pour-over | 9 | Kalita, 15 g, medium-light Guatemala. Mazzer's suggested 10 was too coarse for him | stated | Hedrick | 5:35 |
| Pour-over | 10 | Mazzer's recommendation for filter | stated | Hedrick | 11:40 |
| Espresso | just under 5 | 20 g dose, medium-light roast | approx | Hedrick | 10:10 |

Cup profile
- Filter is cleaner than a stock Kinu or a J-Max-class burr but below a K-Plus or Comandante, with bold notes and a slightly acrid finish 11:40.
- Espresso has full body and texture but is muddled, with little clarity 11:40.
Strengths
- Premium materials, very compact when taken apart, and a snug catch cup 11:40.
Weaknesses
- 33 µm steps are too coarse for fine espresso dialling 2:33.
- The collar gets knocked mid-grind, settings 2 and 3 are very slow and powdery, and the Soft burr is slow 11:40.
Verdict
In 2022 Lance Hedrick found it a lovely object that didn't move the flavour forward, with better options at the price 11:40. In 2024 he gave it a C, with a taste geared to dark roasts 16:45.
