Specs
| Dial | Stepless. A larger number means finer, which is the reverse of most grinders 0:31 |
| RPM | Knob from 1 to 9, roughly 200 to 1400 rpm. James Hoffmann mostly ran it in the middle 0:31 6:05 |
| Burrs | Tested with SSP High Uniformity. SSP Unimodal is suggested for filter only 0:31 |
Starting settings
There are no grind numbers from James Hoffmann. With the High Uniformity burrs he used ratios of around 1:2 to 1:2.5 7:15.
These are the settings each creator gave, measured from their own grinder's zero. Use them as a starting point.
| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Pour-over | 200, 800 and 1400 rpm compared at one grind | 200 was brightest and fastest, with about 0.5% lower extraction. 800 was the most balanced. 1400 was more complex but close to bitter, and slower | stated | Sprometheus | 1:30 |
| Espresso | 200, 800 and 1400 rpm compared, each dialled to time | 200 had the most clarity and acidity and the highest extraction. 800 gave the most balanced shot. 1400 had upfront sweetness, a heavy body and the lowest extraction | stated | Sprometheus | 3:00 |
| Espresso | finer than for a traditional shot | SSP multi-purpose burrs, a turbo shot of 40 g or more in 20 s, light to medium single origins | approx | Sprometheus | 7:42 |
Cup profile
- With High Uniformity burrs, the espresso is textured, balanced and complex, and the filter is good, better than a conical 0:31 2:31.
- In the 2021 showdown the espresso was well textured. The filter had more texture but less clarity, and the slowest drawdown of the group 20:15 15:11.
Strengths
- Very quiet and compact, you can get into the burr chamber without tools, and there are lots of accessories 0:31.
Weaknesses
- The numbering runs backwards, the RPM scale is arbitrary and the dosing cup is oversized 0:31.
- Some old grounds come out after a big grind change 20:15.
Verdict
2021: the best single-dose flat-burr grinder for the money 0:31, and an excellent espresso choice if space or budget is tight 20:15. 2025: still an excellent alternative to the Zerno Z1 26:12.
Kyle Rowsell's take
- 2022: his daily driver and a near-perfect home flat. Retention was about 0.15 g after weeks of use, the 300 to 1400 rpm motor is very quiet, stock alignment is near perfect and the burrs come out without tools. The burrs you choose set the cup: stock is thick, HU is clearer, and multi-purpose suits filter and modern espresso. It scratches easily, chirps from chaff, needs RDT and has a shallow dose cup. It's much quieter than the P100, but has no auto-purge 0:31 6:58.
Sprometheus's take
- 2022: with SSP multi-purpose burrs it made very clear, bright, nuanced black coffee with little body, so it's poor for milk. Retention was under 0.2 g with RDT, and the motor never hesitated at any speed. About $1,800. His rpm test found low speed brightest, high speed sweetest and heaviest, and the middle balanced. He calls variable speed fun rather than essential and keeps it in the middle most of the time 9:14 6:02.
- 2023, a year on: still his last grinder, with no wear, a dependable motor and alignment that held. RDT moisture makes beans stick to the lid, though, the speed dial is vague, the factory zero drifted coarser and the new Mizen burrs needed a stack of shims 5:06.
Brian Quan's take
- 2022: with SSP multi-purpose burrs it was very clear with searing acidity, and quieter but slower than the P100. You're paying for workflow and quality of life rather than flavour, since the same burrs fit cheaper grinders. For a rounder all-rounder he suggests SSP Cast Lab Sweet burrs 7:45 12:09.
