Smooth, low‑acid, naturally sweet — the easiest brew you’ll ever make.
Cold Brew Coffee
Ingredients
1 cup (85–100g)
coarse‑ground coffee
4 cups (1 liter)
cold, filtered water
Optional
milk, cream, sweetener, flavored syrups
Instructions
1. Grind Coarse:
Use a coarse grind — similar to raw sugar. Too fine will over‑extract and create sludge.
2. Combine:
Add coffee grounds to a jar or pitcher, then pour in cold water. Stir to fully saturate.
3. Steep:
Cover and steep for **12–24 hours** in the fridge. Longer steep = stronger concentrate.
4. Strain:
Use a fine-mesh sieve, paper filter, or cold-brew infuser to remove all grounds.
5. Serve:
Dilute concentrate 1:1 with water or milk. Pour over ice and customize to taste.
6. Store:
Keep refrigerated for up to **7–10 days** for best flavor.

If your coffee tastes off, brew time is often the cause. Learn how to fix it in our guide to coffee brew time.

🌡️ Brew Ratios That Matter
- Standard: 1:4 (concentrate) → dilute 1:1
- Ready‑to‑drink: 1:8
- Extra strong: 1:3
Brand angle: “Cold brew is a concentrate — strength is your choice.”
🎯 Flavor Control
- Too weak? Steep longer or use more coffee
- Too bitter? Shorten steep time
- Too muddy? Grind coarser
- Too sharp? Add a splash of milk or simple syrup
Strength and balance come down to ratio. Dial it in with our coffee-to-water ratio guide.
🧊 Why Cold Brew Works
Cold water extracts fewer acids and bitter compounds, giving you:
- smoother flavor
- lower acidity
- natural sweetness
- long shelf life
