1Zpresso J-Ultra: The Ultimate Precision Grinder for Espresso

The 1Zpresso J-Ultra Manual Coffee Grinder is the next evolution of the J-Max, designed for coffee lovers who demand exceptional precision—especially for espresso. With its robust 48mm stainless steel burrs, the J-Ultra delivers ultra-fine, consistent grinding while maintaining effortless control. Thanks to an advanced titanium coating, the burrs stay sharper for longer and grind more smoothly, even under heavy use.

Unmatched Precision for Espresso Grinding

Like the J-Max, the J-Ultra features 1Zpresso’s award-winning external adjustment dial. Unlike many hand grinders that require removing the catch cup to change grind size, this intuitive design allows for quick and easy adjustments—similar to professional electric espresso grinders.

Each click adjusts by just 8 microns, offering pinpoint accuracy for dialing in espresso shots. With multiple full rotations and dozens of micro-adjustments per turn, the J-Ultra is 1Zpresso’s most precise grinder yet, even surpassing the J-Max’s 8.8-micron steps. While optimized for espresso, it’s also versatile enough to grind for manual brew methods like pour-over or French press.

Sleek, Ergonomic, and Built for Convenience

Beyond performance, the J-Ultra boasts a refined, ergonomic design with subtle curves for a comfortable grip. A standout feature is the magnetic catch cup, which eliminates the hassle of screwing and unscrewing—a small but game-changing convenience.
