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 0 to 500 clicks.

  2. Grind and look. You want pieces about the size of coarse sea salt. Coarse settings go quickly by hand.
  3. Steep. Give it 18–22 hours in the fridge, or 12–14 on the counter.
  4. Taste and adjust. Too bitter? Go coarser next time. Too sour? Go finer. Move about 50 clicks at a time.
