⚡ Quick Answer
Your cold brew is bitter because it’s over-extracted—usually from steeping too long, grinding too fine, or using too much coffee.

🔬 Why It Happens
Cold brew extracts slowly, but it still follows the same rules:
- Too long steep time (over 24 hrs) pulls out bitter compounds
- Grind too fine increases surface area and over-extracts
- Too strong ratio (too much coffee) intensifies bitterness
🔧 How to Fix It
- Use a coarse grind (like raw sugar)
- Steep for 12–18 hours (start here)
- Adjust your ratio (try 1:4 concentrate → dilute 1:1)
- Strain thoroughly to remove fines
