Kernwerk Feinmahl 40 Hand Grinder

The Feinmahl 40 is built around a 40 mm hardened stainless conical burr set held in dual bearings, so the shaft doesn't wobble and the grind stays even from the first crank to the last. Adjustment is a stepped dial under the burr — each click moves the gap a small, repeatable amount, which makes it easy to log a setting for pour-over and return to it after a coarser French press session. The 35-gram hopper covers a large mug or a two-cup brew in one fill. Uniform particle size matters because evenly sized grounds extract at the same rate; fewer fines means less bitterness in the cup. The whole grinder disassembles without tools for brushing out. Heavy for travel, ideal on a counter.
