Mavo Phantox Pro, 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 0 to 119 clicks.

People who own one report 80–119 clicks. Our starting point is 100 for a medium roast, and it moves with the roast.

How to use it

  1. Set it. Set the dial to 88–100 clicks. That is the light roast setting. Use the table above for anything darker.
  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 12 clicks at a time.

Let the app keep track.

Cold Brew Studio shows the dial created for your Mavo Phantox Pro with the setting marked, sizes the batch to your brewer, and moves the dial for you when you rate how it tasted.
