Mahlkönig X54 Allround, set for a light roast

The setting, by roast

Lighter roasts are harder to pull flavor out of, so they grind a little finer and steep longer. Darker roasts go the other way. The dial runs from 1 to 35.

Where the number comes from

The maker points to 30–35 for cold brew. Our starting point is 32.5 for a medium roast, and it moves with the roast.
