Context
- Hario Slim: long-time budget champ (~30 GBP), ceramic burrs, poor alignment
- KINGrinder P1: same price (33 GBP), metal burrs, surprisingly good build quality
Particle Analysis
- KINGrinder produces more fines than Comandante but far fewer large boulders than Hario
- Fewer boulders = more even extraction
Blind Tasting Results
- Hario: thinnest, most astringent
- KINGrinder: balanced, pleasant, few complaints
- Comandante: best overall but 7x the price
Espresso Test
- Possible but not a strength. Acidic, lacking sweetness and body.
Key Insight
"We obsess over fines, but at this level, boulders matter more." "I'm happy I can recommend a 33-pound grinder to coffee beginners."
