1Zpresso K-Ultra manual coffee grinder

1Zpresso K Ultra is an enhanced version of the now discontinued K-Max by 1Zpresso. Introducing enhanced creature-comfort features such as a foldable crank handle and smoothed edges in its design.

External grind adjustment with multi-touch capabilities

The 1Zpresso K-Ultra in particular and the K-series blenders in general are well known for their external grind adjustment mechanism. The mill size adjustment ring is designed on top of the body, with numbers from 1 to 9 extremely easy to remember. Currently, other blenders on the market mainly use the grinding mechanism on the down side (Timemore, C40, …) and the upper grinding adjustment (Kinu M47, 1Zpresso JX-Pro, etc.) …). K-series sets itself apart from the rest, aiming for speed and convenience. There are a total of 90 clicks in the sizing section, meaning each click shifts the blade by 22 microns. You can completely control over the grind size from fine to coarse. 1Zpresso K-Ultra is known for its multi-purpose grinding ability, providing good grind quality, high uniformity and consistency, suitable for all preparation methods.

48mm “K-burr” Stainless Steel

1Zpresso K-Ultra is equipped with a 48mm conical stainless steel inner mill that is fixed between the bezel and a dual bearing to ensure that no parts will wobble or come loose during long-term use. The mill is manufactured thoroughly, requiring sophisticated processing techniques to provide the best grinding experience and durability over time. The 1Zpresso K-Ultra’s 48mm blender delivers faster and more consistent blending.

Solid, luxurious and high-class design of 1Zpresso K-Ultra

The outside of the machine is made of aluminum alloy, very thick and high gloss. Heavy-duty parts such as the handle and the inner frame are all made of stainless steel. In addition to the metal parts, there are details such as a walnut knob and a silicone cover with the 1Zpresso logo printed on it to help prevent slipping during the grinding process. The magnetic coffee holder is still retained, although K-Ultra has removed the handy bottom indentation function of K-plus instead of a closed drawer. The sealed compartment of the 1Zpresso K-Ultra is also improved with a bottom covered with a fabric cover to prevent slippery. The 1Zpresso K-Ultra’s magnetic closed drawer is suitable for those who do not use machine coffee a lot, do not really need the bottom indentation function of K-Plus.
