La Région Délimitée du Douro et le Vin de Porto — un terroir historique —

Abstract

La viticulture de la Région Délimitée du Douro, une des héritières de la viticulture ancestrale, traditionnellement empirique et de qualité, tout en intégrant la modernité et les outils contemporains, respecte et a toujours présent les principes sur lesquels elle s’est développé.

Commes les a très bien définit M.Champagnol :
1. La nécessité de réserver les meilleures terres pour les céréales destinés à la nourriture humaine ;
2. La production de moûts riches en sucre afin de contourner le problème de la mauvaise conservation des vins peu alcoolisés ;
3. Les petits récipients vinaires qui imposaient une vinification en petit volume, et qui ont permis d’établir des corrélations entre les parcelles et le vin,
sont quelques facteurs qui ont orienté cette viticulture vers un objectif de qualité.
Ce chemin de la qualité – qui conceme l’authenticité du vin et, Évidemment, la garantie donnée au consommateur, qui est le dernier juge de la qualité -, est un long chemin que l’on poursuit depuis presque 300 ans dans la Région Délimité du Douro.

Somatic embryogenesis and polyploidy in grapevine: morphological shoot and leaf traits variations

Somatic embryogenesis (SE) has been used in a variety of biotechnology applications such as virus elimination, cryopreservation, induced mutagenesis and genetic transformation. The SE induction process may cause DNA alterations and ploidy changes, which may provide a source of genetic variability useful for the improvement of agronomic characteristics of plants. This research aims at investigating the spontaneous alterations of the genome in grapevine plants regenerated through SE. Regenerants obtained from different embryogenic events from three different grapevine genotypes (Catarratto, Frappato and Nero d’Avola) were analysed.

Effect of Botrytis cinerea and esca on phenolic composition of berries and wines

This study showed that Botrytis cinerea could degrade the phenolic compounds by its enzymatic activity. It led to a diminution of skin’s anthocyanins from 20 % to 50 % and an increase level up to 40 % of individual proanthocyanins, 30 % of the %G and 25% of the %P.

NEUROPROTECTIVE AND ANTI-INFLAMMATORY PROPERTIES OF HYDROXYTYROSOL: A PROMISING BIOACTIVE COMPONENT OF WINE

Hydroxytyrosol (HT) is a phenolic compound present in olives, virgin olive oil and wine. HT has attracted great scientific interest due to its biological activities which have been related with the ortho-dihydroxy conformation in the aromatic ring. In white and red wines, HT has been detected at concentrations ranging from 0.28 to 9.6 mg/L and its occurrence has been closely related with yeast metabolism of aromatic amino acids by Ehrlich pathway during alcoholic fermentation. One of the most promising properties of this compound is the neuroprotective activity against pathological mechanisms related with neurode-generative disorders including Alzheimer’s and Parkinson’s disease.

Recognition of terroir in american viticultural areas

Un’ Area di Viticultura Americana, detta AVA, è una regione vinicola delimitata ed è dis­tinguibile da caratteristiche geografiche i cui confini sono stati definiti da regolamenti. Il sistema AVA rappresenta un ‘accettazione del concetto di terroir (terreno), come dimostra­no gli studi che confermano il carattere regionale dei vini AVA e dalla sviluppo di sub­denominazioni più relazionate al terreno.
