1Zpresso K-Ultra review (2026)
1Zpresso K-Ultra is a hand grinder that suits Moka pot, AeroPress and Pour-over. From €282.90 delivered to Finland, prices vary by country.
A 48 mm all-rounder that reviewers favour for filter and AeroPress, with quick method switching. Its 20 micron steps are too coarse for serious espresso dialing.
Best for
- Pour-over and AeroPress drinkers
- People who switch between brew methods
- Travellers who want a foldable handle
Skip if
- Espresso is your main drink
- You want the lowest cost
- You have small hands and a weak grip

- Latvia €283.99
- Estonia €283.99
- Poland €288.99
- Finland €282.90
- Germany €287.99
Brew methods
The 760 µm ceiling per Honest Coffee Guide falls short of cold brew and barely reaches French press.

Pros and cons
Pros
- The numbered external ring with 100+ clicks makes switching brew methods quick.
- Reviewers say the 48 mm burr is fast and even, with a clean cup.
- The foldable handle and included case help travel.
- It is easy to clean and calibrate, with few parts.
- Coffee Chronicler says the redesigned burr gives a smoother, cleaner aftertaste than the older K-Max, with less static.
Cons
- Steps of 20 microns are too coarse for precise espresso dialing, and reviewers point to the J-Ultra instead.
- It is the priciest K-series grinder.
- Some reviewers worry the folding handle could become a weak point over time.
- It is about 700 g and hard to grip for small hands, mostly at fine settings.
What owners report
- Ritual over precision. RoastAroma's owner summary says many keep it for the ritual and portability, not espresso consistency.
- Espresso fans move to the J-Ultra. Owners who shift toward espresso tend to upgrade to the J-Ultra, per the same summary.
- Handle durability question. The folding handle draws long-term worry, but Home Coffee Expert's unit survived a drop in its first week.
What experts measured
- BrewCoffeeHome notes about 45 seconds for 18 g of espresso and under 30 seconds for filter.
- RoastAroma lists retention at about 0.2 g.
- 1Zpresso lists 20 microns per click and a 700 g weight.
