Viticultural characterisation of soils from triassic period at Beaumes-de-Venise (Côtes du Rhône, France)

The classification of enological tannins has gained importance following the OIV’s requirement to include their botanical origin on product labels (OIV-OENO624-2022).

Current changes of ecoclimatic indicators may cause significant variation in grapevine phenology and grape ripening. Climate change modifies several abiotic factors (e.g. temperature, sunlight radiation, water availability) during the grapevine growth cycle, having a direct impact on the phenological stages of the grapevine, modulating the metabolic profile of berries and activating the synthesis and accumulation of diverse compounds in the skin of berries, with consequences on the composition of the grapes.
The influence exerted by different meteorological conditions, during three consecutive years (2020-2022) on secondary metabolites such as the polyphenolic profile of Grignolino grapes was investigated. The samples were collected from three vineyards characterized by different microclimatic conditions mainly related to the vineyard aspect and to a different age of the plants.

I risultati delle ricerche condotte in un vigneto sperimentale di Marsala (TP), scelto per omogeneità di fattori bio-agronomici (età, tecniche colturali, potenzialità vegetativa e produttiva)

Le but de notre travail a été d’étudier l’influence de différents systèmes de la gestion du sol en viticulture sur des paramètres biologiques de sol comme indicateurs de la protection et de la qualité du sol. La conservation de sol est indispensable pour une viticulture durable et la protection du terroir. Nos résultats ont montré, que la matière

For the chemical characterization of Aszu wines from Tokaj region our aim is to develop a biochemical method which is related to Botrytis cinerea.
