Sodium Metabisulfite is a common wine additive and sanitizer. It is traditionally used to inhibit wild yeasts and bacteria from fresh fruit prior to fermentation. It is also used after fermentation for its anti-oxidant and preservative effects. In white wines, it can also preserve color and prevent browning. The addition of sulphites is also claimed to improve the overall flavor of wine and preserve delicate qualities.
