Tea tastes bitter mostly because over-extraction releases too many natural tannins, polyphenols, and caffeine into the water. [1, 2, 3]
Common Causes of Bitter Tea
Water too hot: Boiling water burns delicate leaves, especially green or white tea, pulling out harsh flavors fast.
Steeping too long: Leaving leaves in water past their ideal time forces extra bitter compounds out.
Too many leaves: Using a high leaf-to-water ratio overpowers the cup.
Low-quality tea: Crushed tea dust or fannings in cheap tea bags release flavor and tannins way too quickly.
Personal sensitivity: Some people are biological "supertasters" who feel bitter tastes much more strongly. [1, 2, 3, 4, 5, 6]
As explained by The Chinese Tea Shop, chemical compounds like catechins and theophylline naturally drive this bitterness. You can learn more about managing brewing temperatures from Tea Curious. [1, 2]
If you want, tell me:
- What type of tea you are brewing (green, black, herbal)
- Water temperature and steeping time you currently use
I can give you an exact recipe to fix the taste.
