Is the Zerno Z1 good for espresso and pour-over?

Yes. The 0–1400um stepless range covers espresso through filter, and the swappable prebreakers let you tune feed rate for each method.

Can I change the burrs?

Yes. It uses 64mm burrs with magnetic blind mounting, so burr sets can be swapped without tools.

What is hyperalignment?

Zerno aligns each unit to under 25um so the burrs sit parallel, which supports consistent particle size.

What comes in the box?

The grinder with a V2 medium-feed auger installed, an anodized single-piece chute, a cleaning brush, an RDT spray bottle and maintenance tools.

Does it work on 220V?

It is offered in 100–110V and 200–240V versions, so pick the one matching your outlet.

How does it compare with the DF64?

The Z1 adds magnetic blind burrs, swappable prebreakers, tighter alignment and a heavier metal build; the DF64 is simpler and uses a different feed design.

About the Zerno Z1

The Zerno Z1 is a 64mm burr grinder that supports a wide range of burr sets, from espresso to pour-over. It is hand assembled in Chicago from stainless steel and aircraft grade aluminum. It uses magnetic blind burrs and swappable prebreakers.

Grind adjustment is stepless and front facing, with a range of 0 to 1400um. The precision micron dial has an internal brass thread on a German ball bearing. The burrs are hyperaligned to under 25um, and every unit ships precision-aligned.

An auger prebreaker with medium and slow feed keeps the feed steady and controlled. A custom drive motor rated to over 5,000 hours of use runs at a consistent 900 RPM.
