| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Pour-over | about 1.5 rotations | Kyle Rowsell's usual V60 setting | approx | Rowsell | 2:01 |
| Pour-over | about 2 to 3 clicks finer than 1.5 rotations | A 15 g centre-pour V60 recipe that needs a finer grind than usual | approx | Rowsell | 2:01 |
Cup profile
- Slightly cleaner and more consistent than the Q2, and it stays clear when you push it further 5:39.
- For espresso it was juicier, fuller and more balanced than the Fellow Opus. The Opus won on filter 22:53.
Strengths
Verdict
2022: in the top two or three hand grinders, just behind the K-Plus 5:39. 2024: grade B, maybe A for the price 6:43.
Kyle Rowsell's take
- In 2022 it was his top hand grinder for filter under $200. It has a tank of an aluminium body and an external dial at 12.5 µm a click, which is more than twice as fine as a C40. Blind V60s had sweetness, acidity, a long finish and almost C40 levels of transparency. It's slow though, taking 50 to 60 s for a fine filter dose. The chamber is small, beans can get stuck in the narrow throat, and it's too slow for espresso 2:34.
- Later in 2022 it was still his own choice under $300 for filter, with a sweet, balanced and transparent cup 8:42.
The Coffee Chronicler's take
- In 2022 he found the new heptagonal burr gives a narrow, acid-forward, sparkling cup that suits mild washed coffees. It was sharper than the K-Max for espresso and sieved slightly more evenly. The short handle and screw-on cup are small gripes, and it's good value at JX-Pro money 1:03.
