Preservation of wine without sulphite addition

In order to avoid wine spoilage, most wineries add sulphur dioxide to the wine. However, sulphites dissolved in the wine can potentially cause allergies. An alternative preservation method without or with significantly reduced sulphite addition has been developed by an international consortium within the EU-funded project "PreserveWine-DEMO", in which the Fraunhofer IGB is involved.
