Caratterizzazione vitivinicola delle “Terre del Piacenziano” ricomprese nella zona D.O.C. “colli piacentini” attraverso l’analisi sensoriale dei vini prodotti

Consumers typically prefer wines with floral and fruity aromas over those presenting green-pepper, vegetal or herbaceous notes. Pyrazines have been identified as causatives for herbaceous notes in wines, especially Bordeaux reds. However, pyrazines are not universally responsible for herbaceousness, and several other wine volatile compounds are known to produce distinct vegetal/herbaceous aromas in wines. Specifically, volatile aldehydes elicit sensations of herbaceousness or grassiness and have been described in wines well above their perception thresholds.

Diurnal changes in the leaves of field-grown grapevine (Vitis vinifera L.) cultivars Syrah and Tempranillo were followed over summer 2009 with respect to gas exchanges. Net photosynthetic rate (AN) of both cultivars rapidly increased in the morning, decreasing slowly until the late afternoon, when reached the lowest values.

Aim: Geographical Indications-GI are commonly used to protect territorial products around the world, such as cheese and wine. This qualification is useful because it improves the producer’s organization, protects and valorizes the distinct origin and quality of the product, increases recognition and notoriety, and adds value for products. Tropical wines are mainly produced in Brazil, India,

The study of the interaction between vineyards and the environment to establish the grapevines in the appropriate places has been applied in wine science for 5000 years. Advances in the field of the zoning have not been uniform in time, and have occupied a preferential place in the contributions of Roman writers of the 1st Century AC, the contemplations of Tokay (1700) and Porto (1756) and works of the second half of the 20th century. Zoning practices today integrate multidisciplinary methodologies (viticulture, enology, soils, climatology, cartography, statistics, computer science) and require further development for future application.

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.
