Hand grinder
Cold brew grind setting for the 1Zpresso J (formerly JX)
90–105clicks
That is where to start with a light roast. It should come out looking like coarse sea salt. Medium roasts go to 98–113 and dark roasts to 105–120.
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 150 clicks.
| Roast | Setting | Looks like | Steep in the fridge |
|---|---|---|---|
| Light roast | 90–105 clicks | coarse sea salt | 18–22 h |
| Medium roast | 98–113 clicks | coarse kosher salt | 14–18 h |
| Dark roast | 105–120 clicks | raw sugar | 10–14 h |
