## A starting Cold Brew recipe

This is where Cuplift starts a new Cold Brew brewer before it knows anything about the coffee. Once you add a bean, the recipe adjusts for roast, process and altitude, then learns from what you taste.

| Coffee | Water | Ratio | Grind | Steep |
| --- | --- | --- | --- | --- |
| 60g | 600ml | 1:10 | 900µm (Coarse) | 16h |

Grind is in microns because a click means something different on every grinder. 900µm is about 30 clicks on a Comandante C40. Filter: Paper or mesh.

### Steps

1. Add 60g coffee at 900µm to a jar or carafe
2. Pour in 600ml room-temp water
3. Stir until fully wetted
4. Cover and steep at room temperature for 16h
5. Strain through paper filter or fine mesh

## Dialling in a Cold Brew

- Grind and steep length do almost all the work.
- If it's thin, steep longer or grind finer; if it's harsh or muddy, the reverse.
- Strength is easiest to fix at the end — dilute the concentrate to taste.

Whatever the problem, change one thing per brew. The [dial-in guide](https://cuplift.app/dial-in) covers the order to fix things in.
