What ratio for cold brew coffee?
Quick answer
For concentrate, use 1:8 by weight — e.g. 60 g coffee to 480 ml cold water. Steep 12–18 hours in the fridge, strain, then dilute 1:1 with water or milk before drinking. Ready-to-drink cold brew is closer to 1:12–1:15.
Step by step
- Coarse grind — extra coarse reduces sludge.
- Combine coffee and cold filtered water in a jar.
- Steep 12–18 h refrigerated; stir once if you like.
- Filter through mesh and paper for clarity.
- Dilute concentrate 50/50 for a standard cup over ice.
