Specs
| Burrs | SSP High Uniformity (HU), SSP Brew v2 Silver Knight, or Mazzer burrs made by Option-O. 98 mm sets need a different carrier 0:31 |
| Dial | Threaded hopper dial with no ticks. The quality-control target is about 10 ticks from burr lock to chirp, and Lance Hedrick's grinder was about 6 0:31 |
| RPM | Positions 1 to 9 measured from about 195 to about 1350 rpm, with a purge at about 1800 0:31 |
Where sources disagree
The creators don't all give the same figure here, so every value is listed with the person who gave it.
| Field | Value | By | Source | Note |
|---|---|---|---|---|
| Burr size (mm) | 98 | Hedrick | 0:00 | |
| Burr size (mm) | 102 | Hedrick | 0:31 | |
| Burr size (mm) | 98 | Sprometheus | 9:49 | stock set, with an optional 102 mm set |
| Burr size (mm) | summary | One Lance Hedrick video gives 98 mm and his full review gives 102 mm. Sprometheus says the stock set is 98 mm with an optional 102 mm set, which may explain the difference. |
Starting settings
No one has shared grind settings for it yet.
| Method | Setting | Context | Confidence | By | Source |
|---|---|---|---|---|---|
| Espresso | RPM position 3 for grinding in the demo (about 420 to 460 rpm) | 20 g dose with HU burrs. Flat nine-bar and ultra-low-contact shots both work | approx | Hedrick | 33:10 |
| Espresso | about 1400 rpm, median particle about 289 µm | Matched to a P64 at a similar grind size for comparison | approx | Sprometheus | 6:29 |
Cup profile
- The HU 102 set is balanced, textured and clear, with a wide range. Brew v2 is tea-like with a long finish. The Mazzer set is round and balanced 0:31.
- Against a $100 OXO it was tea-like, juicy and balanced, with no drying finish 0:00.
Strengths
- About 0.1 g retention with the knocker and a purge 16:44.
- An ionizer, and an auger for an even feed 0:31.
Weaknesses
- The horizontal burrs hold grounds a little longer, which Lance Hedrick doesn't like 12:42.
- A stiff dial, and the price 0:31.
Verdict
2026: an excellent combination with the HU 102 burrs, but unnecessary if you already own a good grinder in the $250 to $500 range 0:31 41:44.
Sprometheus's take
- 2024: excellent, but overkill at home. It has 98 mm Mizen blind burrs (a 102 mm set is optional), 7.5 µm per notch, 200 to 1700 rpm, about 5.5 g/s and 0.1 g retention. Cups were sweet and bright above 20% extraction on light roasts, with a lighter body. It costs about $1,000 more than a P64 for nearly the same result 9:49.
