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.

Drought responses in Chardonnay and Sauvignon blanc grapevine cultivars: Mechanistic insights and varietal contrasts

This study explored the responses of Chardonnay and Sauvignon blanc grapevine cultivars to water deficit across four years, uncovering their shared patterns and distinctive coping mechanisms. The research was conducted in a commercial vineyard located in Isla de Maipo, Chile. Various characterization approaches were employed including plant water potentials (), gas exchange measurements, shoot vulnerability curves, productivity assessments, and leaf cell water relations. Linear mixed models and sensitivity analyses were performed using various statistical methods to evaluate cultivar responses to water deficit. As the water deficit progressed, both cultivars displayed a parallel reduction in stomatal conductance, leaf turgor, and increased shoot embolism.
