Will Potassium Sorbate change the taste, smell, or appearance of my food or drink? No, when used correctly it is tasteless and odorless, and wont alter color or texture. If overused though, some wine makers note off-flavors, so its important to follow guidelines carefully. What does Potassium Sorbate do when I add it to homemade wine? When added after fermentation, it stops yeast from reproducing which helps prevent re-fermentation, over-carbonation, or spoilage in wines, ciders, or sweetened beverages. When should I add Potassium Sorbate: before, during, or after fermentation? Only add it after fermentation is complete and the wine or cider is fully cleared. It does not stop active fermentation, but rather prevents future yeast growth.
