⚡ Quick Answer
Your coffee is weak because it’s underdosed or over-diluted. Use more coffee, less water, or adjust your ratio to increase strength.

🔬 Why It Happens
Weak coffee happens when there aren’t enough dissolved coffee solids in your cup. This usually means:
- Too little coffee
- Too much water
- Or extraction wasn’t strong enough
🔧 How to Fix It
- Use more coffee (stronger ratio)
- Use less water
- Check your ratio (start around 1:15–1:16)
- Make sure your brew time isn’t too fast
