Worth it if you brew across multiple methods and want one dial to cover them; espresso-only brewers chasing the tightest possible adjustment may prefer the J-Ultra's finer steps instead.

Overview
The 1Zpresso K-Ultra is a manual conical burr grinder in iron gray with a carrying case, adjusted through an external dial in 20-micron steps that spans coarse brewing down to espresso fine.
Positioned as the broad-range grinder in the 1Zpresso lineup, it's built for people who brew more than one way rather than espresso alone, which is the main thing separating it from the J-Ultra below.
- Stainless steel conical burr built for multiple brew methods
- External dial gives over 100 clicks at 20 microns per step
- Magnetic catch cup holds 35 to 40 grams of grounds
- Foldable handle and carrying case, plus a cleaning brush and air blower included
Who it's for
Home brewers who move between espresso, French press and pour-over and want a single grinder to cover that range, plus anyone who wants a manual grinder that folds down for travel.
Pros and cons
- Covers a wide grind range on a single external dial
- Foldable handle and included carrying case for travel
- Magnetic catch cup speeds up the grind-and-dose routine
- Tool-free disassembly with a brush and blower included for cleaning
- 20-micron steps are coarser per click than the espresso-focused J-Ultra
- Manual grinding takes more time and effort than an electric burr grinder
Performance notes
A stainless steel conical burr feeds an external dial offering over 100 clicks at 20 microns per step, covering French press through espresso fine on one grinder. A magnetic catch cup snaps into place and holds 35 to 40 grams of grounds, and the unit disassembles without tools for cleaning, with a brush and air blower included. The burrs are factory-calibrated and rated for 100-200 kg of coffee over their life, backed by a one-year warranty.
