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


[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.

During wine aging many compositional changes take place. In particular, aroma undergoes dramatic modifications through a wide range of reactions that to date are only partly understood. Italy owns one of the largest ampelographic heritages worldwide, with over three-hundred different varieties. Among these, many white grapes are employed for the production of dry still white wines. Some of these wines are consumed young while others are more prone to aging. For many of these wines, the aging patterns related to volatile composition are still unknown.

Grapevine sensitivity to fungal diseases: use of a combination of terroir cartography and parcel survey

In front of the economic interest and seeking to respect their environment, the wine growers move gradually towards a policy of reasoning their plant health protection. This is why, starting from epidemiologic studies on grapevine pathogens, forecasting models of the risks are developed by research and experimentation bodies.

Metabolomic profiling of heat-stressed grape berries 

The projected rise in mean air temperatures together with the frequency, intensity, and length of heat waves in many wine-growing regions worldwide will deeply impact grape berry development and quality. Several studies have been conducted and a large set of molecular data was produced to better understand the impact of high temperatures on grape berry development and metabolism[1]. According to these data, it is highly likely that the metabolomic dynamics could be strongly modulated by heat stress (HS).

Impact of crop load management on terpene content in gewürztraminer grapes

Context and purpose of the study ‐ Crop load management by cluster thinning can improve ripening and the concentration of key metabolites for grape and wine quality. However, little work has been done on testing the impact of crop load management on terpene content of white grapes. The goal of the study was to assess if by reducing crop load via cluster thinning growers can increase terpene concentration of grapes, as well as to test if the timing of thinning application affects terpene concentration.

Using ΔC13 to assess viticultural and oenological suitability for Sangiovese of different pedoclimatic conditions in Chianti

A two years trial was carried out in Chianti (Central Italy) to assess at the detailed scale the viticultural and oenological suitability for Sangiovese of different pedoclimatic conditions, by means of the ΔC13 measured in the must sugars
