SO2 Addition as Potassium metabisulfite (K2S2O5)
The potassium metabisulfite (K2S2O5) is a white crystalline salt, which contains 57.6 % sulfur dioxide (SO2). Potassium metabisulfite is dissolved in warm water before being used. When is added into juice/must or must it reacts with natural acids to release sulfur dioxide, which protects wines from unwanted microorganisms and oxidation.
