Pigment compounds in grape skins responsible for red wine color.

Full Definition

Anthocyanins are water-soluble pigments found in the skins of red and black grapes. They give red wine its color, ranging from purple-blue in young wines to brick-red in aged wines. During aging, anthocyanins polymerize with tannins, creating stable color compounds while softening the wine's texture.
