Potassium Metabisulfite 1 Lb

Potassium metabisulfite 25 kg 1/8 tsp gallon = approx. 100 ppm free so2 superior in several ways to sodium metabisulfite. An antibacterial agent identical in use to sodium metabisulfites but does not add sodium to wine. Added to wine to inhibit bacterial and yeast growth as well as retard oxidation. May leave unpleasant aftertaste in wine if dose is too high. Yields approximately 50 per cent as sulfur dioxide. For a sanitizer - use 2 oz per 1 gallon of water. For use as an antioxidant & bactericide - use two-thirds teaspoon to 5 gallons of wine. Dissolve sapphire in a little warm water before adding. Potassium metabisulfite is a common additive used to preserve and stabilize wines, ciders, and occasionally beers. When added to wine or must, it forms sulfur dioxide gas (so2).
