Cold brew is brewed without heat, highlighting sweetness and body while keeping acidity low. This easy method makes a concentrate you can dilute with water, milk, or serve over ice.
What you’ll need
- Fresh-roasted coffee (100 g, coarse grind)
- Filtered water (1,000 g / 1 L)
- Bottle or jar with lid (≥1.2 L)
- Cheesecloth or coffee filter
- Fine strainer
- Scales (optional)
Step 1. Grind coffee
Weigh 100 g coffee and grind coarse, similar to French press.
Step 2. Add water & saturate
Combine grounds with 1 L cold or room-temperature water in a bottle or jar. Stir well to ensure all grounds are saturated.
Step 3. Steep 12–24 hours
Cover and refrigerate for at least 12 hours (up to 24 for a stronger concentrate). Give it a gentle shake halfway through if you can.
Step 4. Strain
Line a strainer with cheesecloth (or a paper filter) and strain into a clean container. For extra clarity, strain twice.
Step 5. Store
Refrigerate the concentrate in a sealed bottle. It stays fresh for up to 2 weeks.
Step 6. Enjoy
Serve over ice. Dilute 1:1 with water or milk to taste. Sweeten if you like.
