Red wine has a high content of phenolic compounds, with a total polyphenol of 215.48 mg /100 mL (32.1 mg /100 mL for white wine) assessed by Folin assay, mainly flavonoids (e.g., anthocyanins, flavanols, flavonols, flavanones), phenolic acids (hydroxycinnamic and hydroxybenzoic acids) and stilbenes (resveratrol, d- and e-viniferin).

The French Paradox suggests that consuming red wine daily not only helps the cardiovascular system, but also increases the lifetime, despite the ingestion of high levels of saturated fat. It is known that excessive alcohol consumption increases the risk of liver cirrhosis and cancer, while low to moderate red wine consumption has been associated with health-promoting properties correlated with their flavonoid compound’s composition. Polyphenols, especially resveratrol play a significant role in cardio protection and has anticancer effects.
