[email protected] Abstract: In the Valpolicella area (Verona, Italy) Vitis vinifera cv. Corvina is the main grape variety Citation: Tomasi, D.; Lonardi, A.; used to produce Amarone wine. Before starting the winemaking process, the Corvina grapes are Boscaro, D.; Nardi, T.; stored in a withering (i.e., dehydrating) warehouse until about 30% of the berry weight is lost (WL). Marangon, C.M.; De Rosso, M.; This practice is performed to concentrate the metabolites in the berry and enrich the Amarone wine in Flamini, R.; Lovat, L.; Mian, G.
