VviSOC1a and VviAG1 act antagonistically in the regulation of flower formation

Acidity of grape berries is lowered due to climate changes (1), resulting in musts and wines with higher pHs. These higher pHs induce microbiological instability

Les paysages participent à l’identité des vins de l’Hérault, avec une grande richesse de diversité. Leur observation, au travers des quatre saisons, s’appuie sur deux dimensions primordiales : la genèse de leur construction par l’homme et l’esthétique. L’hiver est la saison la plus favorable au décryptage de ce vignoble étagé, du littoral méditerranéen aux premières pentes du Massif Central; il permet de lire l’histoire des stratégies viticoles des vignerons. Les autres saisons sensibilisent plus à la beauté de vignobles dans des écrins de végétation typiquement méditerranéenne. La multiplicité des pratiques culturales et des cépages contribue à cet attrait. L’incitation au parcours, en toute saison, est très forte grâce au réseau des routes et des chemins de vigne.

In recent decades, sustainability has risen to prominence across various industries, including agriculture, spurred by initiatives such as the new common agricultural policy and the farm to fork strategy within the European Union. Among agricultural activities, viticulture stands as a crucial player in sustainability, intertwining environmental, social, and economic dimensions, as exemplified by the OIV general principles of sustainable viticulture. Italy, one of the main players in the global wine market, has long been making efforts towards the introduction of sustainability-oriented practices and certifications.

Il caso “Lambrusco” è emblematico di un buon connubio tra un gruppo di vitigni ed un territorio di pianura caratterizzato da suoli fertili e alluvionali, che determinano un elevato sviluppo

Wine aroma is influenced by various factors, from agricultural practices in the vineyard to the enological choices made by winemakers throughout the vinification process. Spontaneous fermentations have a characteristically deeper complexity of aromas when compared to fermentations that have been inoculated with Saccharomyces (S.) cerevisiae because of the diversity of microflora naturally present on grape skins. Non-Saccharomyces yeast are being extensively studied for their ability to positively contribute to wine aroma and flavour. These yeasts are known to liberate more bound volatile compounds present in grape must than S. cerevisiae through the enzymatic action of β-glucosidases and β-lyases1.
