Steps
- Add the coffee to the jar, pour in the cold water, and stir until every ground is wet.
- Cover and steep in the fridge for 14–16 hours.
- Strain through a paper filter or fine sieve into a clean bottle.
- Serve over ice, diluted with water or milk to taste — the concentrate is strong.
Tips
- Keeps up to a week in the fridge, so brew a big batch on Sunday.
- Coarse grind is essential; fine grounds make it muddy and bitter.
Ready-to-Drink or Concentrate?
Use the Cold Brew ratio calculator and comparison chart to choose between a ready-to-drink 1:8–1:12 brew and a 1:4–1:6 concentrate that is diluted after filtering.
Compare this method with espresso-based drinks in the Iced Coffee recipe collection.
