Cold brew coffee ratio
Cold brew is steeped for hours, so you make a lot at once. 1:8 is a ready-to-drink strength. 1:5 makes a concentrate that you dilute with water or milk, usually about 1:1.
Change any field and the others update. Typical range for cold brew: 1:4 to 1:10.

- Example
- 100 g of coffee and 800 ml of water makes about 600 ml, because the grounds hold back about twice their weight in water.
Steps
- Combine the coffee and cold water in a jar and stir until all the grounds are wet.
- Cover and steep 12–18 hours, in the fridge or on the counter.
- Strain through a paper filter or fine mesh. A second pass through paper removes the silt.
- Keep it in the fridge and drink within about a week.
Tips
- Fridge steeping is slower and lighter, so lean toward 18 hours. On the counter, 12 hours is often enough.
- If a concentrate tastes harsh, dilute it more before changing the recipe.
