The catch
1Zpresso K-Ultra Manual Coffee Grinder
With 20-micron clicks, espresso gets less fine control than on the J-Ultra.
Side by side
1Zpresso K-Ultra vs X-Ultra: X-Ultra needs less packing room but handles a smaller dose
Quick verdict
Thanks to its larger capacity and highly regarded all-round burr, the K-Ultra is the stronger primary hand grinder. The X-Ultra saves space and has closer 12.5-micron clicks, for a traveler who can live with a smaller dose.
