Total polyphenols comprise a broad family of compounds that are fundamental to wine quality, particularly in red wines. They contribute to colour, structure, astringency, stability and antioxidant capacity.
Their determination makes it possible to assess:
the degree of extraction from skins and seeds;
wine structure;
ageing potential;
colour stability;
phenolic evolution over time.
The relationship between polyphenols, anthocyanins and tannins provides valuable information for interpreting the wine profile and making decisions on maceration, ageing and blending.
