Does Wine Contain Sodium Metabisulfite?
Yes, many wines do contain sodium metabisulfite. This compound is commonly used as a preservative and antioxidant in winemaking. It helps prevent spoilage and oxidation, which can negatively affect the flavor and quality of the wine.
- Sodium metabisulfite releases sulfur dioxide (SO2) when dissolved, which is effective in preserving wine.
- Both red and white wines may contain this additive.
- Some wines labeled as "sulfite-free" may have lower or negligible amounts, but most commercial wines do use it at some stage of production.
If you are sensitive to sulfites or prefer to avoid additives, look for wines labeled as "organic" or "no added sulfites."
