Étude de l’adaptation des cépages Muscat à petits grains et Muscat d’Alexandrie dans l’A.O.C. Muscat de Rivesaltes

Climate change is a great environmental challenge with large impact on the Wine and sprakling wine industry. Heat waves and dryness cause frequent sunburn damage in white grapes

Climate change has brought several impacts that are becoming increasingly intense during the last few years and put at risk the quality of the berries or even the plant’s sustainability. Such extreme climatic events impact the composition of the wine while modulating its quality and the consumer preferences (Tempère et al., 2019). The three most important changes that take place in the must are: 1) decrease acidity, 2) increase of the concentration of sugar, hence increase of alcohol in the wine, and 3) modification
of the sensory balance and the development for example of cooked fruit aromas.

Analisi sulle zonizzazioni storiche, sulle produzioni tipiche ed originali e sulla “forestazione classica” per impostare innovative zonazioni vitivinicole e dei prodotti tipici, originali attraverso la “Nuova forestazione storica produttiva”. Le recenti ricerche ed attività svolte sulle zonizzazioni storiche, sulle produzioni tipiche ed originali e sulla “forestazione classica” dei Monti Iblei (Ragusa) (I) hanno permesso di rilanciare le produzioni tipiche ed originali vitivinicole in un innovativo programma integrato tra zonazione (“Grande Zonazione”) e “Nuova forestazione storica produttiva” (“Grande Forestazione Produttiva”) di questo importante territorio.

The metabolomics era started about 22 years ago, and wine was one of the first foodstuff subjects of analysis and investigation by this technique.

Aroma diversity is one of the most important features in the expression of the varietal and geographic identity and sensory uniqueness of a wine. Italy has one of the largest ampelographic heritages of the world, with more than five hundred different varieties. Among them, many are used for the production of dry still white wines, many classified as Protected Designation of Origins and therefore produced in specific geographical areas with well-defined grape varieties. Chemical and sensory characteristics of the aroma of these wines have never been systematically studied, and the relative diversity has never been described and classified.
