J-Ultra Manual Coffee Grinder
A $199 espresso hand grinder with 8-micron external steps and 48 mm coated burrs; superb shots, but weak for pour-over.
- 8-micron external steps give extremely fine espresso control
- Balanced, full-bodied, clean espresso in reviewer tests
- Very low retention (about 0.1 g on an 18 g dose)
- Manual grinding takes about 35–55 seconds per espresso dose
- Fine steps make switching between roasts or brew methods easy to lose track of
