Sulphur dioxide is one of the oldest known food additives and has been used in wine since ancient times when sulphur was burnt before sealing the wine in the barrels. It also develops naturally in wine as part of the fermentation process. However it is also added as a preservative to prevent oxidation of the wine and at the grape-crushing stage as a cleansing agent to kill unwanted bacteria and wild yeasts. This innovative range of wines produced and bottled without the addition of sulphur dioxide, has been developed as a natural extension of Stellar's commitment to organic winemaking.
