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.

The use of elicitors in the vineyard to mitigate the effects of climate change on wine quality

The wine sector is being directly affected by climate change. Temperatures above 30ºC can cause a lag between the ripening of the berry pulp (a rapid increase in sugar content) and the skin

Adsorption capacity of phenolics compounds by polyaniline materials in model solution

The aim of this work was to study the trapping capacity of four polyaniline polymers towards phenolic compounds in wine-like model solutions. METHODS: The model wine solution was composed of 12% (v/v) and 4 g/L of tartaric acid adjusted to pH = 3.6. A series of centrifuge tubes (15 mL) were filled with 10 mL of model solution enriched with 50 mg/L of five phenolic compounds (i.e., Gallic acid, caffeic acid, (+)-catechin, (-)-epicatechin, and rutin), and treated with different doses of PANI polymer (i.e., 0, 2, 4 and 8 g/L). After the addition of the polymer, the samples were stirred using a platform shaker at room temperature (20 ºC) for 2, 8, 16 and 24 h. All treatments included three replications.

Evaluating the effectiveness of alginic acid, sodium carboxymethylcellulose, and potassium polyaspartate in preventing calcium tartrate instability in wines

Calcium-induced instabilities present a major challenge in bottled wines, with calcium tartrate (CaT) precipitation becoming increasingly common due to rising calcium levels in grape must, largely driven by climate change. Although CaT is an insoluble salt, its instability— although less frequent than potassium hydrogen tartrate (KHT) precipitation—is more difficult to predict and control, as it develops gradually over time.

Zonazione dell’area viticola doc durello

Il lavoro di zonazione riveste un ruolo importante per capire le potenzialità e la vocazionalità di una specifica area viticola. La viticoltura dovrebbe essere vista in funzione dell’obiettivo enologico che si vuole realizzare e quindi particolare importanza riveste il risultato delle vinificazioni delle uve provenienti dai vigneti delle diverse aree della zona di produzione oggetto d’indagine. La zonazione dell’area a DOC Monti Lessini Durello ha preso in esame la varietà “Durella”, vitigno autoctono del territorio, che rappresenta la maggior parte della produzione vitivinicola della zona.

Chemical and sensory quality, environmental sustainability, and consumer acceptance of South Tyrolean wines produced from hybrid grape varieties

Disease-resistant hybrid grape cultivars (DRHGCs) are hybrids of Vitis vinifera varieties with other Vitis species, and they are endowed with greater resistance to specific fungal diseases, enabling a potential reduction in the application of pesticides in the vineyard.
