Cold brew grind setting for the Comandante C40 MK4
32–36clicks
That is where to start with a light roast. It should come out looking like coarse sea salt. Medium roasts go to 34–38 and dark roasts to 36–40.
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 40 clicks.
| Roast | Setting | Looks like | Steep in the fridge |
|---|---|---|---|
| Light roast | 32–36 clicks | coarse sea salt | 18–22 h |
| Medium roast | 34–38 clicks | coarse kosher salt | 14–18 h |
| Dark roast | 36–40 clicks | raw sugar | 10–14 h |
Where the number comes from
The maker points to 25–35 clicks for cold brew. People who own one report 32–40 clicks. Our starting point is 36 for a medium roast, and it moves with the roast.
