Abstract

During wine aging and maturation, anthocyanins can react with flavanols (directly or mediated by aldehydes) and with small molecules derived from yeast metabolism during fermentation. It has been demonstrated that A-type vitisins (the main pyranoanthocyanins found in red wines) can react with other wine components yielding pyranoanthocyanin pigments with different colors ranging from yellow to turquoise blue. Wine-color chemistry has been an inspiration for the synthesis of new molecules with unique chromatic features.
