A quality or substance that causes a tightening effect on tissues, often resulting in a dry or puckering sensation in the mouth.
The astringency of the wine made it a perfect match for the rich cheese.
Astringency → It is formed from "ad-" (meaning to) and "stringere" (meaning to bind or draw tight). The word describes the quality of being able to bind or constrict tissues, often used in the context of certain substances that cause a tightening effect.
Think of something that 'binds' or 'tightens' ('stringere') when it comes into contact with tissues — that's why astringency refers to that tightening quality.
