Wine market is very competitive. EU producers need to reduce production costs and increase their sustainability standard while improving the quality of their wine. Wine stability is one of the most important quality parameters. To avoid formation of cloudiness or precipitates in bottled wines, producers preventively treat it by mean of physical methods or additives. The present practices for tartaric, protein and oxidative stabilization are not suitable for each type of wine and production facility, in particular in small wineries (conventional and organic); moreover, they involve a large use of energy or water, can negatively affect overall wine quality and processing, impose sometimes the use of large quantities of coadjunts or additives, and can be at the original of significant product looses. Aim of the project is to test effectiveness and suitability in winemaking of biopolymers on new conception or already used in other sectors and to make these new practices available for EU SME wine producers. Addition of biopolymers to wine have shown the ability to inhibit the formation of tartrate crystals, potentially without negative side effects and with no use of energy and water. Other types of biopolymers are known for their ability to absorb proteins in a selective way, and can be adapted to winemaking purpose in order to avoid loss of product and to increase sensorial wine quality. Potential economical, environmental and social benefits are relevant. The project include evaluation of the effect of the treatments on human health and environment, and actions to facilitate the authorization of the new practices by international and European regulatory bodies for conventional and organic winemaking. Extensive dissemination and exploitation activities are foresees to allow fast tak-up of new technologies by SME-AG members and by all European wine producing SMEs.
