Starting settings
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 |
|---|---|---|---|---|---|
| Espresso | 65 to 80 clicks from zero | Sprometheus's espresso range | stated | Sprometheus | 3:10 |
| Pour-over | 170 to 180 clicks from zero | Sprometheus's filter range, nearly 100 clicks coarser than espresso | stated | Sprometheus | 3:40 |
Cup profile
- Brighter, more acidic and clearer than a Niche Zero, which leans towards texture and balance. For espresso the line between flat and conical blurs 7:23.
Strengths
- Comes apart magnetically without tools, has a tighter spread than a Niche Zero, retains about 0.1 g with RDT and has a sturdy 12 lb body 7:23.
Weaknesses
- Heavy static (you really need RDT), dust on the burrs, a 75 to 80 dB squeal and a big power brick. At $800 it's up against a Niche Zero or Lagom Mini 7:23.
Verdict
2024 (Sprometheus): capable and unusual, but priced into an awkward spot against cheaper conicals 7:23.
Notes
- Lance Hedrick's 2024 tier list gives it an A for low retention, easy stripping, solid alignment, and good filter and espresso 11:22.
