Zerno offers a wide variety of burr sets to accommodate a spectrum of preferences.
Zerno Z1 is designed to be compatible with a wide variety of 64mm burrs, which offers the ability for users to experiment and choose their ideal grind. Which burr set you use depends on your preferred coffee style, desired taste profile and roast level. We collaborated with SSP to manufacture the first 64 magnetic blind set - currently only compatible with the Z1.
