Know before you buy
The Z3 is equipped with HG6-38 CNC-machined stainless steel burrs. These are designed to provide a consistent grind size, which is essential for achieving a balanced extraction in your cup.
The hopper has a bean capacity of 25 grams, and the catch cup can hold up to 30 grams of ground coffee. This is generally enough for a single large pour-over or two smaller cups.
The Z3 features a durable, integrated aluminum alloy body. This construction provides a solid, premium feel and ensures the grinder remains stable while you are manually operating it.
The CNC-machined stainless steel burrs are capable of producing a wide range of grind sizes. While it performs exceptionally well for manual brew methods like pour-over, it can also handle the finer settings required for espresso.
Because the Z3 is a manual grinder with a stainless steel construction, you can easily disassemble the burr set for cleaning. We recommend using a soft brush to remove residual coffee oils and grounds after regular use to maintain grind consistency.
