Z2 Production Is Gaining Momentum
Z2 production is hitting its stride as we’re shipping out more and more grinders every day.
The team has been working around the clock to scale production without compromising the precision that defines the Z2. We’re producing more components in-house, we’ve invested in new equipment and machines that are already online at Zerno HQ, and output is climbing.
Every grinder still goes through the same rigorous process that ensures hyperalignment, tight tolerances, and hand-verified assembly. But we’re taking the steps necessary to expand our operation so we can build more of them, faster, and get them out the door sooner. The result: Fulfillment times are steadily coming down.
Inside the Z2 Production Process
Take a deeper look at what makes the Z2 unique, and what it takes to build one, in these new posts from the Zerno Content Hub:
Machined for Hyperalignment: Inside the Z2
What does it actually take to achieve hyperalignment and near-zero retention in an 80mm flat burr grinder? This article walks through the manufacturing decisions behind the Z2: in-house machining, <10-micron tolerances, supercooled press-fit assemblies, and the engineering philosophy that ties it all together.

Connecting with the Coffee Community
World of Coffee in San Diego was one for the books. Thank you to everyone who stopped by our booth, got hands-on with the Z1 and Z2, or just spent time talking coffee with the team.
Events like this give us an unparalleled opportunity to connect with our fellow coffee lovers, and we bring all of that input and energy back with us to the shop floor. There’s no better way to experience why the work matters, and we were grateful to be a part of it.
SEY House
During World of Coffee 2026, the Z2 also made an appearance at SEY House. SEY is one of Brooklyn’s premier roasters, and their commitment to a quality and intentional coffee experience made the collaboration a natural fit. It was a great getting to see the Z2 in action alongside some of the best coffee in the country.
Community Spotlight: HYUNAH Coffee Club
HYUNAH Coffee Club is a reservation-only clubhouse in Greenpoint, Brooklyn built for home coffee enthusiasts. It’s a space to explore premium brewing equipment, specialty coffees, education, and community. It’s run by a fantastic and passionate team, and it’s exactly the kind of community infrastructure that specialty coffee needs more of.
We’re proud to see the Z1 and Z2 included in HYUNAH’s grinder lineup. It’s a privilege knowing that coffee lovers from around New York City are using Zerno grinders as they gather to taste, test, compare, learn, and build their own point of view.
Thanks for being part of the Zerno community.
