1Zpresso J-Ultra review (2026)
1Zpresso J-Ultra is a hand grinder that suits Espresso, Moka pot, AeroPress, Pour-over, French press and Cold brew. From €202.90 delivered to Finland, prices vary by country.
Reviewers rate it among the best hand grinders for espresso: 48 mm burr, 8 micron steps and near-zero retention. It is weaker for filter, and fine grinding takes effort.

Pros and cons
Pros
- Steps of 8 microns on an external dial give very fine espresso control.
- Retention is very low: CoffeeGeek weighed it and called it extremely low.
- An 18 g espresso dose takes about 40 to 50 seconds, which reviewers call fast for a hand grinder.
- Reviewers praise the balanced cup, with body and a clean finish.
- Owners on a retailer page praise the build, case and cleaning kit.
Cons
- It is less clean for filter coffee, because the burr makes more fines than the K-Ultra.
- Switching between espresso and coarse methods takes many clicks.
- Fine grinding with dense or light roasts takes real effort.
- The magnetic cup can pop off if you brace the grinder hard.
What owners report
- Precision and speed. Owners on the 4barista retailer page praise precise adjustment and fast, comfortable grinding.
- Better than a built-in grinder. One owner says shots were far better than from a machine's built-in grinder, per the same page.
- Filter is secondary. Several reviewers point to the K-Ultra or X-Ultra for filter. A few owners still say it does filter well enough.
- Price is the main complaint. Where owners complain, price is the main point. Two compare it favourably with the Comandante.
What experts measured
- RoastAroma lists retention at about 0.1 g.
- CoffeeGeek timed an 18 g espresso dose at 40 to 50 seconds.
