What is Resveratrol?
Resveratrol is an antioxidant primarily found in Japanese knotweed, blueberries, red grape skin, and peanuts. Plants produce it to protect themselves against stresses. Hence, antioxidants fight age-related damage by neutralizing them from free radicals.
In Wine and Red Grape
Red grapes plants produce Resveratrol to protect against fungal disease and sun damage, so the wine has a higher antioxidant level than most other food items. Red wine contains less than 1- 2 mg of Resveratrol per eight ounces, which is more than white wine.
Additionally, red wines are fermented with grape skins for a more extended time than white wine; antioxidants such as Resveratrol are likely to be extracted into wine, leading to the higher resveratrol concentration of the red stuff.
Moreover, humidity is another important factor contributing to the resveratrol content. It theorized that grapes grown in humid environments produce antioxidants to address the higher fungus rate in these areas. More Resveratrol means more antifungal properties.
