Instruction :
I don't like how my coffee tastes. What are some reasons that the coffee I brew isn't good?

Response:
- Using too much or too little coffee can make the coffee too strong or weak. 
- Grinding coffee too finely can make it too strong and bitter, or too coarsely can make it weak. Use the right grind for your brewing method; finer for drip coffee, coarser for french press.
- The quality of the coffee beans affects the flavor of the brewed coffee. Fresh high-quality beans can improve the coffee's flavor.
- Fresh-ground coffee will typically make better brewed coffee than previously-ground coffee
- The temperature and quality of the water can affect the coffee's flavor. Hard water can negatively impact the coffee's flavor.
