Sulphur dioxide (or SO2, sulphur dioxide, sulphite)

SO2 protects and stabilizes wine. SO2, the glass bottle and the cork are the major discoveries that allow the conservation of wine over long periods of time. The doses used are low, adjusted precisely as needed by laboratory analysis. A small part of the population is allergic to SO2, hence the mandatory label statement “contains sulphites”.
