“Terroir” studies in the Côtes du Rhône controlled appellation: from zoning to application

This work aims at identifying the most appropriate marketing strategies to inform consumers of the global market about the added value of the wines of Friuli Venezia Giulia.

The creation of disease-resistant varieties adapted to climate change is a key challenge for the future of the wine industry. At present, the selection of these new varieties is essentially based on screening for genetic markers of resistance and agronomic criteria, due to the small number of vines available per genotype. Integrating screening for oenological criteria into the early stages of selection would speed up this process.

Yeast-derived aroma compounds are the result of different and complex biochemical pathways that mainly occur during alcoholic fermentation. Many of them are related -but not limited- to the availability of nutrients in the fermentation medium and linked to nitrogen metabolism and biomass produced. Besides, the metabolic phase of yeast also regulates the expression of many enzymes involved in the formation of aroma active compounds. The work investigates the overall effect of continuous supplementation of nutrients during alcoholic fermentation of a grape must on the volatile composition of wines.

Il mondo del vino si è accorto che per la sua comprensione, valorizzazione e promozione è fondamentale conoscere le ragioni geologiche del vino, valutare il suo impatto sul paesaggio e acquisire il suo valore emozionale.

Wine quality and safety are the main concerns of consumers and health agencies. Biogenic amines and polyamines, depending on their concentration and on individuals, in wine can constitute a potential public health concern due to their physiological and toxicological effects
