The Hario Mini Mill grinder makes an affordable, high quality coffee grinder if you set it up properly. Unfortunately, the directions are not very clear as to how to adjust for the perfect grind.


Screw adjustment nut all the way down

Remove the bottom canister and screw the adjustment nut as tight as it goes. This serves as a reference for the next step.

The way to measure your grind is by "clicks" away from all the way tight. You'll feel the nut click as you unscrew, so count the number of clicks. The number of clicks to unscrew should vary based on the brew method you're using. Here's the general guide I use:

TypeNumber of Clicks
Standard Drip Brew10 clicks
#2 Pour over10 clicks
Aeropress6-8 clicks
Espresso5 clicks
French Press12-14 clicks
Moka pot9 clicks
Chemex9 clicks

Also if you're looking for the more vague ones:

TypeNumber of Clicks
Medium fine8 clicks
Medium10 clicks
Medium coarse12 clicks
