Description
Potassium Sorbate is a wine stabilization additive used to prevent re-fermentation in finished wines, particularly when residual sugar is present. It works by inhibiting yeast reproduction, helping ensure your wine remains stable after sweetening and bottling.
This product is most commonly used when making off-dry or sweet wines, dessert wines, fruit wines, and ciders. Potassium Sorbate does not kill active yeast, so it should always be used after fermentation is complete and in combination with potassium metabisulphite for best results.
When used correctly, Potassium Sorbate helps preserve the intended sweetness, clarity, and balance of your wine without impacting flavour or aroma. It is a standard, widely accepted stabilizer in both home and commercial winemaking.
