5. Coffee grounds = Water / Ratio (1 : X) = 1,000 / 8 = 125

Did we solve your problem today?

Cold brew uses a strong ratio (often 1:8 for concentrate, diluted before drinking).

The math behind it

coffee (g) = water (g) ÷ ratio. Steep 12–24 h, then dilute concentrate ~1:1 with water or milk.

1,000 g water at 1:8 → 125 g coffee.
