Insights on the stilbenes in Raboso Piave grape (Vitis vinifera L.) as a consequence of postharvest vs on-vine dehydration.

The findings increase knowledge of stilbene composition in grapes subjected to withering on-vine. The choice of dehydration method affects the contents of these nutraceuticals in the grape and consequently in wines. Reasonably, it could also affect other secondary metabolites important for wine quality. © 2017 Society of Chemical Industry.
