Sodium Metabisulfite 8 oz

SODIUM METABISULFITE - Sanitizer - use 2 oz per 1 gallon of water. Antioxidant and bactericide - use 2/3 teaspoon to 5 gallons. Dissolve sulphite in warm water before adding.

Sodium Metabisulfite is less expensive than Potassium Metabisulfite, but contains the sodium ion, which some winemakers would prefer to avoid. Use the same way and in the same proportions as Potassium Metabisulphite.
