This project is born with an ambitious objective: reducing by 90 per cent the environmental impact of wine production in south-west Europe. With this aim WETWINE will carry out a pilot experience to promote the rational use of the resources of the area and the reuse of waste from the grape and wine-growing industry. The project then plans to transfer the results to the major denominations of origin of the Sudoe space such as Rioja, Douro, Rías Baixas, and Pays d’Oc.
