Today, I was trying to describe a taste, not sweetness, not bitterness, not saltines, not sourness in English, and I couldn’t figure it out. After research, I found the word I need- ASTINGENCY. It is a taste that “contain tannins or calcium oxalate that cause an astringent or puckering sensation of the mucous membrane of the mouth.” There are two more things I learned: A taste from Japanese- Umani and the “tongue map” of taste is an incorrect interpretation of our tongue sensation.
