Potassium Sorbate Stabilizer - 1 oz

Potassium sorbate is used in winemaking to "stabilize" a wine and prevent a renewed fermentation, especially when sweetening a wine prior to bottling. Potassium sorbate does not kill yeast cells but instead inhibits the yeast cell from being able to multiply, grow and begin a new fermentation. 

Use 1/2 tsp per gallon.
