Cold brew grind setting for the Timemore Chestnut C3 Pro
19–22clicks
That is where to start with a light roast. It should come out looking like coarse sea salt. Medium roasts go to 21–24 and dark roasts to 22–25.
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 30 clicks.
| Roast | Setting | Looks like | Steep in the fridge |
|---|---|---|---|
| Light roast | 19–22 clicks | coarse sea salt | 18–22 h |
| Medium roast | 21–24 clicks | coarse kosher salt | 14–18 h |
| Dark roast | 22–25 clicks | raw sugar | 10–14 h |
Where the number comes from
People who own one report 20–25 clicks. Our starting point is 22 for a medium roast, and it moves with the roast.
