The ceramic conical burr mill produces consistent grounds perfect for pour-over, Chemex, cold brew, espresso, siphon, and for use with automatic brewers. To Adjust the Grind Unscrew the top and remove the handle. Lift the burr locking fork. Rotate the cogwheel clockwise to tighten the burrs for a finer grind; or rotate counter-clockwise to loosen the burrs for a more coarse grind.
