Platform For Experimentation
Unlock Potential. Explore Every Flavor
The Z2 was designed for those who never stop tinkering—prosumers and professionals alike.
Supporting a wide range of 80mm burrs, it makes experimenting, swapping burrs, and holding your
grind settings effortless, all while maintaining flawless alignment—no shims needed.
Easily swap between two-hole and three-hole burrs—traditional or blind. With effortless access and a
system aligned by design, you can zero in on grind profiles for espresso, pour-over, and everything in
between.
Burr changes don’t reset your grind journey; they deepen it.

Auger Prebreaker System
Smoother Feeds. Fewer Fines.
Born from years of experience, the Z2’s all-stainless steel auger and grind chamber reduce retention while feeding beans with precision.
Redesigned from the Z1, the auger slows bean feed rate below burr speed, minimizing backpressure and fine generation for a cleaner, clearer cup.
Brushless Servo Motor
Precision You Can Hear(Or Can't)
The Z2’s heart is an industry-first, direct-drive 600W brushless AC servo motor—custom
developed by Zerno.
Operating across a universal 100–240VAC input, the motor maintains
constant torque and speed, delivering consistent grinds regardless of load.
All Stainless Steel Grinding Components
Built to Last. Engineered to Perform.
The entire grind mechanism in the Z2 is crafted from precision-machined stainless steel,
ensuring rigidity, longevity, and reliability.
This industrial-level build quality translates directly
into consistent results and reduced maintenance over time.
Precision Micron Dial
Luxurious Feel. Control Every Micron.
At the front of the Z2 sits the smoothest precision micron dial in the industry.
Built with an internal brass thread and mounted on a German ball bearing, the dial delivers feedback you can feel—precise, fluid, and tactile.
Setting the zero point is effortless, accurate, and repeatable. You’ll feel when the burrs touch—just like sensing road texture in a high-performance sports car. It’s feedback made physical, the interface between human and machine.
The Z2’s magnetic accent piece allows quick, tool-less access to the zeroing mechanism and creates opportunities for personalization.
Whether matched to a kitchen, café, or personal taste, it’s designed to adapt seamlessly—simple, functional, and made to look right at home in any setting.
