⚡ Quick Answer
Your coffee tastes sour because it’s under-extracted. Grind finer, brew longer, or use slightly more coffee to bring out balance and sweetness.

🔬 Why It Happens
Sourness comes from early-stage extraction. Water pulls acids first—but if it doesn’t extract long enough, it never reaches the sweeter, balanced compounds.
🔧 How to Fix It
- Grind finer (slows water, increases extraction)
- Increase brew time
- Use a slightly lower water ratio (more coffee)
- Check water temp (195–205°F)
