Reduless (3 g)
Reduless is a new product from Lallemand that was designed to correct negative VSCs (Voltatile Sulfur Compounds) such as H2S (hydrogen sulfide, A.K.A. "rotten egg") and DMS (dimethyl sulfide, A.K.A. "cooked corn") defects in wine. Made from inactivated yeast that have been infused with copper using a proprietary process, Reduless is a much gentler H2S remedy on the wine than the traditional copper sulfate (CuSO4) treatment alone. If you have an H2S problem, then we recommend treating it with Reduless first. However, if the sulfur problem still remains after the Reduless treatment, then a bench trial with copper sulfate (CuSO4) is recommended.
Note: The sooner you catch a sulfur problem the easier it is to deal with!
Dissolve Reduless in 10 times it's weight in water and add immediately to the wine. Stir the wine gently to ensure a thorough homogenization. Rack or filter after 72 hours.
0.4-0.6 g/gal. The maximum amount of copper that can be released into the wine using Reduless at the recommended dosage is 0.02 ppm.
