Abstract

The color evolution of malvidin-3-O-glucoside (Mv-3-O-glc), elicited by caffeic acid (CAF), (+)-catechin (CA), or syringic acid (SI) in model wine solution, was spectrophotometrically monitored over 12 months of storage, considering different malvidin-to-polyphenol molar ratios (1:1 to 1:20) and pH values (2.8–3.6). The dataset belongs to a comprehensive study aimed at modelling the copigmentation onset and its impact on the color of red wines.
