Sulphiting

Sulphiting means adding sulphur dioxide (SO2) to a drink, usually wine, fruit wine or juice. It acts as an antioxidant and inhibits unwanted micro-organisms, so freshness, colour and shelf life are better preserved. A small amount also forms by itself during fermentation.

Because of possible intolerances, the note “contains sulphites” must appear on the label from a certain concentration. Permitted maximum amounts are limited by law for each type of drink. The applicable regulations are decisive. Some producers sulphite minimally or not at all, which requires greater care.
