Campden Tablets Potassium Metabisulfite 1 OunceUse one Campden tablet per gallon. Contains potassium metabisulfite and is a convenient way to accurately sulfite wine. Releases sulphur dioxide, which acts as a sterilant and antioxidant. 100 per bag.Potassium Metabisulphite is an antioxidant. It slows down the aging and oxidation of wine by removing free oxygen suspended in the wine. Potassium metabisulfite is often called a stabilizer because it serves to prevent spoilage and further fermentation by removing oxygen. However, adding potassium metabisulphite preserves the flavor and color of a wine. Each of these is able to bond with free oxygen floating around in wine. When this happens the free oxygen is no longer available to be consumed by micro-organisms. The removal of oxygen chokes off most micro-organisms and will prevent them from reproducing. Sodium Metabisulfite can be used interchangeably with potassium metabisulfite. While they both have very similar chemical makeups the difference is that potassium metabisulfite leaves potassium behind and sodium metabisulfite leaves sodium behind.
