Proprietary product which contains potassium metabisulfite, ascorbic acid and tannin in premeasured amounts. The ascorbic acid is supposedly used to increase the effectiveness of sulfite (SO2). Actually, research has shown that SO2 protects wine better without ascorbic acid present. Use only as directed by the manufacturer. See ascorbic acid and Tannin.
