Abstract

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
La preocupación por el cuidado de la salud y el medio ambiente por parte de los consumidores de vino está aumentando en los últimos años, centrándose el interés en los vinos elaborados con prácticas de producción de bajo impacto en el uso de productos químico. Una de las estrategias potenciales es pasar de un enfoque orientado al tratamiento químico a un enfoque de prevención de enfermedades mediante la utilización de variedades resistentes a hongos, generalmente conocidas como uvas híbridas o cruzamientos interespecíficos. En este estudio, se investigaron los vinos elaborados a partir de cinco variedades resistentes cultivadas en el Instituto Estatal de Viticultura y Enología de Friburgo (Cabernet Cantor, Cabernet Cortis, Cabernet Carbon, Prior y Regent) y provenientes de parcelas experimentales ubicadas en la Provincia de Trento. Los vinos fueron sometidos a evaluación olfativa, y el perfil volátil estudiado por cromatografía de gases-olfatometría (GC-O). Las regiones seleccionadas de los cromatogramas fueron investigadas en detalle por GC-MS
