Potassium Sorbate arrests fermentation and is used as an additive before bottling to prevent re-fermentation in the bottle. It does not kill yeast and therefore is not a fungicide, but prevents fermentation by interfering with the metabolism of the yeast.
- Its properties are dependent on the combined presence of sulfur dioxide, alcohol, and acidity.
- Other names: Potassium-2,4-hexadienoate.
Application: Should be added just prior to bottling.
