Polyphenolics uses only non-fermented seeds and skins from California wine grapes and juice grapes collected in the Central Valley of California. E&J Gallo Winery, the California Natural Color & Polyphenolics parent company, is the largest wine company in the world so we have a large supply of raw material to choose from.
