Preservative free wine and the use of sulphur dioxide is, however, an expansive and contentious topic and getting to the bottom of it can feel like trying to crack the Da Vinci Code. Preservative free wine is a really a misnomer.

Potassium metabisulfite is a food preservative, which preserves the natural color of food and protects food against bacteria. Winemakers also use potassium metabisulphite to preserve bottled wines.The manufacturing industry uses potassium metabisulphite as a dye and printing agent, in gold processing and in photography for developing.ine. The winemaking industry uses potassium metabisulfite as an additive during the bottling process. When they add potassium metabisulfite to the wine, a sulfur dioxide gas forms, which destroys microorganisms in the wine and prevents molds and bacteria from growing inside the wine bottle.
