❄️☕ Why Is My Cold Brew Bitter?

⚡ 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

🎯 Bottom Line

Cold brew should be smooth—not harsh. Shorten steep time and go coarser, and you’ll get a sweeter, cleaner cup.
