Cold brew ratios, made simple

Cold brew uses far more coffee than hot brewing because cold water extracts slowly.
  • Concentrate (1:5): a strong base you dilute 1:1 with water or milk when serving
  • Ready-to-drink (1:8): brew it to sip straight from the fridge

Use a coarse grind, steep 12–24 hours (16 is a great starting point), then filter. See the full how to make cold brew at home guide.

Frequently asked questions

What is the ratio for cold brew?

Use 1:5 (coffee to water) for a concentrate you dilute 1:1, or 1:8 for a ready-to-drink batch. For example, 200 g coffee to 1000 ml water makes a 1:5 concentrate.

How long should cold brew steep?

Steep 12–24 hours, using 16 hours as a reliable starting point. Shorter is weaker and more sour; past 24 hours can turn bitter.
