Potassium Metabisulfite is used in must or wine to prevent oxidation and/or spoilage. It can be used both in a powder or liquid form to sprinkle over grapes prior to crushing.
- Its action in water inhibits harmful bacteria through the release of sulfur dioxide.
- It can also be used as an antiseptic agent to sanitize tanks, lines and pipes.
- Note: Its strength is about 17% greater than Sodium Metabisulfite and should be mixed accordingly.
Application: Can be added at any stage of the winemaking process.
