Preservative free wine is a really a misnomer. This is because no wines are truly ‘preservative free’ as some sulphur dioxide will always be released during fermentation and acts as a natural preservative. The term ‘preservative free’ is often used to mean that no preservatives have been added during the wine making process.

Japanese knotweed extract (Polygonum cuspidatum) Resveratrol 98% Resveratrol in grapes, supplements and other foods. The resveratrol in red wine comes from the skin of grapes used to make wine. Because red wine is fermented with grape skins longer than is white wine, red wine contains more resveratrol. Simply eating grapes, or drinking grape juice, might be one way to get resveratrol without drinking alcohol.
