Profundización del conocimiento sobre el aroma de las variedades de vinos tintos resistentes a los hongos producidos en Trentino

Concern about health and environmental care by wine consumers is increasing over the last years, focusing the interest on wines produced by low chemical production practices. One of the potential strategies is to shift from a treatment-oriented approach to a disease-prevention approach by the utilization of mold-resistant varieties, usually known as hybrid grapes or interspecific crossings. In this study, the wines produced from five resistant varieties bred at the State Institute of Viticulture and Oenology of Freiburg (Cabernet Cantor, Cabernet Cortis, Cabernet Carbon, Prior and Regent) and coming from experimental plots sited in the Province of Trento were investigated. Wines were subjected to orthonasal evaluation, and the volatile profile studied by gas chromatography-olfactometry (GC-O). The selected regions of the chromatograms were further investigated by GC-MS
