Starting settings
No one has shared grind settings for it yet.
Cup profile
- Full body, creamy and balanced, and at its best with dark to medium roasts. It mutes light, fruity or experimental coffees, and its particle spread is close to the Eureka Libra's 8:05.
Strengths
- Grind by weight was usually within 0.2 g in Sprometheus's tests and never more than 0.5 g off. The grounds come out fluffy, and it's rated for about 17 lb a day 8:05.
- In the café it was quiet, compact and accurate to about 0.2 g, and it spread the grounds evenly into the basket 2:33.
Weaknesses
- 2 to 3 g sits in the chute, so you need to purge. The small knob makes it easy to lose your setting, cleaning takes tools and time, and clarity is low 8:05.
Verdict
2024 (Sprometheus): it stands out for grind by weight, its price against rivals and its commercial durability. In the cup it tastes like the smaller Libra. $1,800 8:05.
Notes
- On a 2026 café visit it was chosen for fast, accurate weighed doses at the espresso bar. It costs under $2,000 depending on burrs and colour 2:33.
