Features of the K-Ultra
More precise adjustment
The K-Ultra adjusts more finely than the other grinders in the K Series. One rotation of the external ring has 10 numbers and 100 clicks, and each click moves the burr by 20 micrometers.
Its own burr
According to 1Zpresso, the heptagonal «K Burr» conical burr is designed for many brewing methods and grinds evenly and precisely. As the largest burr in the 1Zpresso range, it grinds 20 g of beans for pour-over in under a minute.
More compact
With the familiar external grind ring of the K Series and the new foldable handle, the K-Ultra is more compact and easier to carry. It stands securely on any surface, and the reworked knob sits comfortably in smaller hands too.
New design
The rounded body with soft edges sits ergonomically in the hand and makes grinding comfortable.
The details in everyday use
Magnetic catch cup
The cup comes off with a twist and is held by 24 magnets. It holds 35 to 40 g, depending on the bean and roast level.
Grip, base and knob
A non-slip grip band gives you hold, the silicone base dampens noise, and the ergonomic wooden knob sits on the foldable handle.
Disassembly without tools
The grinder can be taken apart and cleaned without tools. 1Zpresso advises against cleaning it with water.

Who the K-Ultra is made for
For anyone looking for a hand grinder for espresso and filter, at home or on the go, without power. Burrs are like engines: there is no objectively best one. Our opinion is one of many.
You'll find more hand grinders in our hand grinders collection, for example from Comandante and Timemore. If you'd rather grind electrically: for anyone who wants affordable, precise grinding, the Varia VS3 from our Varia collection; if you want more, the EG-1 from Weber Workshops. Our advice tool and a free consultation appointment help you narrow things down. If you'd like to compare grinders side by side, book the espresso machine and grinder comparison in Zurich Oerlikon (Hagenholzstrasse 50b) or Bern (Gerberngasse 44). It is an option, not a requirement. Not every model is set up at all times, so send us the model you'd like to see in advance at [email protected].
Goes well with: brewers like the AeroPress or pour-over and French press from our filter equipment, and if you want more, the BIRD from Weber Workshops. For espresso by hand, a lever machine from Flair Espresso. For scales, Normcore is compact and precise, Acaia comes with an app and flow rate display.
