Tannin is a word used to describe a natural chemical found in plants, particularly in things like tea, coffee, and red wine. Tannin makes these things taste bitter and dry. If you're having a cup of tea or a glass of red wine and you notice a dry, puckering feeling in your mouth, that's the tannin. This word is often used in discussions about beverages and the taste sensations they create.
