Where do the grape seeds and grape skins come from?

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