Yes - 64mm blind burrs are a Zerno innovation, and only compatible with the Z1 grinder.

Different burr designs can express different qualities of the bean, producing a wide range of flavor profiles, body, and finish. See our burr guide for more information.

Our auger designs control the flow of beans into the grind chamber, and can impact the flavor profile and body of your brew. See our prebreaker page for more information.

At Zerno, we craft our grinders from premium, durable materials designed to last — reducing waste and our environmental impact. This same care goes into our packaging, which is purpose-built to protect your Z1 during shipping.

We encourage you to keep your original packaging. Should your grinder ever need to come back to us or be shipped elsewhere, it ensures safe travel and helps us all uphold a commitment to sustainability.
