Polyphenols are natural compounds that show a wide spectrum of biological actions potentially beneficial for the human health. Wine is an alcoholic beverage that contains a large amount of polyphenols extracted from grapes during the processes of vinification. These molecules are associated with anticancerogenic, antidiabetic, neuroprotective, hormonal, antimicrobial, cardioprotective, and other health effects of wine.
