A general phenological model for characterising grape vine flowering and véraison

In 2008 the anthocyanin, flavonol and hydroxycinnamate (HCT) contents of the skins of five coloured berry cultivars (‘Escursac’, ‘Esperó de Gall’, ‘Galmeter’, ‘Valent negre’ and ‘Vinater negre’), of two white cultivars (‘Argamussa’ and ‘Prensal blanc’) and of one weakly rose cultivar (‘Giró ros’), native from Balearic Islands, were characterized.

Organic wines, although resulting from a production method based on the non-use of synthetic phytosanitary products, are not always free of residues. These residues can result from cross-contamination during production in the field or in the cellar, during the production or aging of the wine. In recent years, with the improvement of analysis techniques, a molecule, phosphonic acid, the main metabolite of fosetyl-al (banned in organic farming) is regularly quantified in organic wines and its origin is not clearly identified.

Nutrients in municipal treated wastewater (N, P, K, mainly) are a particular advantage in this source over conventional irrigation water sources

Sensory analysis of grape berries is a common tool to evaluate the degree of grape maturation and to make sound picking decisions.

In the next years the territorial environmental certification could become realistic if the following conditions will be fully satisfied:
– the enhancement of the environmental awareness among the industries, the public administration, the authorization bodies, the living people of that territory as well as the tourists and visitors.
