Product Description

Potassium metabisulfite is one of the most important winemaking compounds. It is an antioxidant and bactericide that releases sulfur dioxide into wine must. Use 1/4 teaspoon per five gallons to add 50 ppm. Or, mix 1/4 pound in 1 quart of water to make a stock solution; 1 teaspoon of stock solution in one gallon of must yields 50 ppm sulfur dioxide.
