Polyphenols in Red Wine
It has long been known that red wine helps keep arteries clean. The question has always been, how? Was it the antioxidants in the red wine?
Polyphenols are a group of chemical substances found in plants, characterized by the presence of more than one phenol group per molecule.

Polyphenols: Chemical class of compounds which occur naturally in wine, giving it an astringent, bitter or mouth-drying taste sensation. Tannins and grape skin pigments are two prominent classes of polyphenols.

This characteristic forces producers to a scrupulous vinification procedure, because an excessive extraction of polyphenols, as well as an excessive aging in cask, can cause wines to be very tannic with a bitter taste.

Tannins are a group of phenol compounds found in plants, which create a group of chemicals called "Polyphenols". These polyphenols are, for the most part, soluble in water.
Procyanidins are the most active polyphenols limiting the production of a protein that causes constriction of the arteries. Roger Corder of Queen Mary College, London has suggested this may go some way to explain the so called French Paradox.
Researchers attribute this result to the presence in red wine of polyphenols, in particular to catechine, and to their antioxidizing properties (see composition of wine).
Technically, they are plant-derived polyphenols. Tannins are often described as the component that "dries the mouth" out in red wines.

Both the bitterness and pungency in oils come from a group of compounds called polyphenols, which are the same class of compounds that produce red wine colour, bitterness and astringency.
Also, the studies have found increased health benefits for red wine over white wine, including cancer protection. Researchers suspect that this may be because red wine contains more polyphenols than white wine.[51] ...
