1Zpresso K-Ultra: The Ultimate Precision Grinder for Every Brew Method

The 1Zpresso K-Ultra Manual Coffee Grinder is the newest and most advanced addition to the K-series, designed for those who demand exceptional grind consistency, precision, and versatility. Like the K-Pro and K-Max, the K-Ultra is equipped with a powerful 48mm stainless steel burr set featuring a unique heptagonal shape, ensuring effortless grinding and uniform particle distribution across all grind sizes, from coarse French press to ultra-fine Turkish coffee.

At its core, the K-Ultra continues 1Zpresso’s tradition of intuitive design with its award-winning external grind adjustment dial, making grind size changes quick and precise without the hassle of disassembling the grinder.

Unrivaled Precision & Enhanced Adjustability

What sets the K-Ultra apart from its predecessors is its enhanced precision. The dial offers 10 numbered grind settings, with a stepped adjustment system featuring 100 clicks per rotation—10 more than the K-Pro—for an even finer level of control. Each click adjusts grind size by approximately 20 microns, making the K-Ultra the most precise grinder in the K-series lineup.
