There’s nothing worse than drink a cup of coffee, which is very sour and bitter in the early morning. And now you make another shot but same results. What happened to the coffee?

here are several reasons why your coffee shot may taste bitter and sour:
Over-extraction: This occurs when the coffee has been in contact with water for too long or the water temperature is too high, causing the coffee to extract more than necessary. To avoid over-extraction, you should use the right grind size, ensure your coffee-to-water ratio is correct, and keep an eye on the extraction time.
Low-quality coffee: Poor quality coffee beans or old coffee can have a bitter and sour taste. Always use freshly roasted coffee beans and make sure they are of high quality.
Inadequate cleaning: Old coffee residue in your coffee equipment can affect the taste of your coffee. Always make sure to clean your equipment after every use.
Water quality: Poor quality water or water that is too hard or soft can affect the taste of your coffee. Use filtered water or bottled water if your tap water has a poor taste.
