Characterization of phenolics and VOCs in wines obtained from Malbec vineyards of the Uco Valley submitted to high-altitude solar UV-B and water restriction

ln the current work, phenolic and cellular maturation curves were used to assess the degree of adaptation of the cultivar Cabernet sauvignon to the sites under esamination. Five wine­-producing zones with different pedoclimatic characteristics and latitudes were considered (Marche, Toscana, Emilia, Friuli and Slovenia).

In sparkling wines, foam is a relevant aspect whose measurement method could affect the results. The shaking test (ST) is a simple method measuring foamability1,2

Un grand nombre d’études ont été consacrées à l’évaluation quantitative des effets de climat sur la qualité des vignes, dans différents contextes climatiques. Généralement, la vocation viticole d’un terroire peut être étudiée par des approches mono ou multidisciplinaires.
