Bound anthocyanins (bANT) are small and large polymeric pigments that form when monomeric free anthocyanins and protein-precipitable tannins polymerize together. Their brick red color is generally more stable, persisting throughout the life of the wine long after free anthocyanins decay. They are resistant to oxidation, sulfur bleaching, and chromatic shifts due to high pHs. Their formation also decreases the hydrophobicity of the associated tannin molecules, modulating astringency and aroma suppression. Overall, they are fundamental for establishing red wine style and serve as a mechanism to integrate wine flavor into phenolic structure.
