Viticultural zoning in D.O.C. Ribeiro (Galicia, NW Spain)

Abstract

[English version below]

L’AOC Ribeiro est la plus ancienne de Galice (NO de l’Espagne), avec une aire de production potentielle de 3.200 ha. Situé dans la région centrale de la vallée du Miño, le Ribeiro a un climat de tipe maritime tempéré qui se correspond avec la zone climatique II de Winkler. Bien que prédominent des variétés très productives (Palomino, Grenache), aujourd’hui beaucoup de vignerons sont en train de substituer ces cépages, au profit des variétés anciennes plus adaptées à la production des vins de qualité.
Le but de ce travail est caractériser les méso climats présents dans cette région viticole et aussi, identifier les endroits les plus favorables pour ces cépages anciens.
Nous disposons des données météorologiques fournies par sept nouvelles stations automatiques au cours de l’année 2003. Pour l’étude viticole, la cave coopérative qui commercialise plus du 60% des vins produits dans la région nous a proportionné les données relatives au degré alcoolique des raisins du millésime 2003. En préliminaire, toutes les données recueillies ont été intégrées à un système d’information géographique (SIG), pour générer la base cartographique du zonage. En ajoutant les données concernant la maturité des vignobles (degré alcoolique) avec un modèle numérique du terrain (MNT), nous avons raffiné le zonage méso climatique initial. De plus, cela nous permit d’identifier les zones mieux adaptées aux exigences des variétés traditionnelles.

The ‘Ribeiro’ is the most historically renowned Denomination of Origin (D.O.) in Galicia and includes some 3,200 hectares. This region is situated in the central part of the river Miño valley in northwest Spain and has a temperate maritime climate corresponding to Winkler´s II zone. Although there are very productive varieties of vines e.g. Palomino or Garnacha, these have been recently substituted by more traditional varieties better suited to the production of higher quality wines.
In the following article, we identify prevailing mesoclimates, in this particular vine growing and wine producing area and characterize the most suitable conditions for these varieties concerned. In order to distinguish among mesoclimates, data provided by seven new automatic meteorological stations during 2003 was utilized. In addition to this, the wine-producing cooperative commercialising over 60% of the production in the area concerned, facilitated details corresponding to Brix degrees when grapes harvested entered the cellars. These data on Potential Alcohol Content (PAC) were introduced into a geographic information system (GIS) for integration with a Digital Terrain Model (DTM) in order to obtain a zonification where mention of the identified mesoclimates present appear together with the most suitable areas for the traditional varieties.

Climate is a pervasive factor in the success of all agricultural systems, influencing whether a crop is suitable to a given region, largely controlling crop production and quality

Implication of secondary viral infections on grafting success rated in nurseries

Grapevine grafting is a complex process that since the establishment of phylloxera has become mandatory for grapevine. Grafting success in grapevine nurseries considerably varies among years and batches with most variety/rootstock combinations reach a high success rate (between 75% and 90%), but some combinations show lower success rates of around 40-50%. The causes of this variation are unknown, although biotic stresses like those caused by some viral infections have been demonstrated to affect the process. European certification schemes for the vegetative propagation of the vine include five major viruses (Arabis mosaic virus, Grapevine Fanleaf Virus, Grapevine Fleck Virus, and Grapevine-associated Leafroll Virus 1 and 3).

Effect of maceration conditions during the winemaking of withered Corvina grapes on wine polyphenols and anthocyanins

Amarone is an Italian red wine with worldwide recognition and high added value. In Amarone wines, grapes undergo a withering process before vinification; this leads to a modification in the concentrations of sugars, acids, and secondary metabolites.

Evolution of several biochemical compounds during the development of Merlot wine in the vinegrowing “Terroir” of Valea Călugăreasa

The qualitative and quantitative distribution of the phenolic compounds in red wines depends on cultivars features, on grapes maturation state, on grapes processing technology including must obtention, as well as on maceration-fermentation method (Margheri, 1981). The last two factors are responsible for the different phenolic composition of the wines produced from the same cultivar.
