Quick Answer
Cold brew steeps coarsely ground coffee in cold water for 12–18 hours, producing a smooth, low-acid concentrate you dilute to taste.
You'll Need
- Large jar or cold brew maker
- Coffee
- Cold or room-temperature water
- Coarse grinder
- Fine strainer or filter
Grind
Extra coarse.
Ratio
Starting point: 1:8 concentrate. For example: 100g coffee → 800g water.
Water
Cold or room temperature — no heat involved.
Brew
- Grind coffee extra coarse
- Combine coffee and water in your jar
- Stir to fully saturate the grounds
- Steep 12–18 hours at room temperature or in the fridge
- Strain through a filter or fine strainer
- Dilute the concentrate with water or milk to taste, and serve over ice
Troubleshooting
- Too weak? → Steep longer, or use less water next time
- Too bitter? → Steep for a shorter time
- Grounds in the cup? → Strain twice, or use a finer filter
Connoisseur Tip
Cold brew concentrate keeps well in the fridge for about two weeks — make a batch once and you'll have coffee on hand all week.
