WineFrog explains Resveratrol
For the vine, it acts as an anti-oxidant during periods in which the vine is undergoing stress, such as periods of low precipitation (dry farming), or if the vine is attacked by fungi or pests.
As it is found in grape skins, this resveratrol is also found in wine. Because red wine is made by the maceration of grape juice with grape skins, it contains more resveratrol than white wine.
Just as it has benefits for the grape and grape vine, it has benefits for those who consume the wine. It also acts as an antioxidant and has many believed benefits which improve heart health, arthritis, cancer, obesity and many other health challenges.
