As a division of Constellation Brands, Polyphenolics has access to an abundant supply of fresh wine grapes, grown in California’s Central Valley, and retains complete control over the entire manufacturing process – from the initial wine grape selection to the final extraction of finished material. The company goes beyond federally mandated traceability requirements, documenting all aspects of growing, treating and handling of the varietal grapes. Through painstaking supply chain documentation and laboratory testing, Polyphenolics can substantiate freshness, identity, domestic origin, and absence of chemical contaminants and genetic modification.
