Cold brew is the most relaxed coffee you will ever make. You stir, you wait, you strain. The result is smooth and low in bitterness, and a single batch covers most of a week of iced coffee.
The cheat sheet: 1 part coarsely ground coffee to 5 parts cold water by weight makes a concentrate. Steep 14 to 18 hours in the fridge. Strain, then dilute about 1:1 with water or milk over ice.
What you need
- A large jar or pitcher
- Coarse ground coffee, like rough sand (a burr grinder gives the most even grind)
- A fine strainer plus a paper coffee filter or cheesecloth
Step by step
- Combine. Stir 150 g (about 1 1/2 cups) of coarse grounds into 750 g (about 3 cups) of cold, filtered water. Make sure all the grounds are wet.
- Steep. Cover and refrigerate for 14 to 18 hours. Longer gets stronger and can turn woody; shorter can taste thin.
- Strain twice. Pour through a fine strainer, then through a paper filter for a clean, sludge-free concentrate.
- Store. Keep the concentrate in a sealed jar in the fridge and use it within about a week to 10 days.
- Serve. Fill a glass with ice, add concentrate, and top with an equal amount of water or milk. Adjust to taste.
Cozy café variations
- Honey vanilla: a spoonful of honey syrup and a splash of vanilla.
- Brown sugar cinnamon: dissolve brown sugar in a little hot water with a cinnamon stick, cool it and stir in.
- Cold brew float: a scoop of vanilla ice cream on top for a weekend treat.
