Zonage viticole des surfaces potentielles dans la vallée Centrale de Tarija (Bolivie)

Abstract

[English version below]

La présente étude de zonage viticole a été faite dans la région de la vallée Central de Tarija(VCT), dans la ville de Tarija, au Sud de la Bolivie; une région avec plus de 400 années de tradition qui présente une vitiviniculture de haute qualité. La Vallée possède une surface total de 332 milles ha.; existant des vignobles entre 1660 y 2300 m.s.n.m. et dans ce rang d’altitude il existe 91 mille ha. avec un haut potentiel pour la culture de la vigne. Pour la détermination des surfaces homogènes de la région ont été considérés les aspects d’environnement avec l’aide d’images satellitaires, des cartes topographiques, des données climatologiques et des cartes géologiques ; pour déterminer les caractéristiques de la région pour la culture de la vigne. Au niveau climatique furent appliqués les indices du Système CCM Géo viticole développés par Tonietto & Carbonneau (2004), lesquelles considèrent des éléments thermiques (Indice Héliothermique), hydriques (Indice de sécheresse) et nictothermiques (Indice de Froid nocturne); nous avons identifié 8 types des climats différents dans toute la région. Dans les particularités du sol furent déterminés la morphologie et il a été géo référencié tous ses caractéristiques (analyses chimique et physique). S’ai fait une classification spécifique des critères de culture de la vigne pour déterminer l’aptitude du sol, en même temps ont été identifié les surfaces avec des limitants pour le conduit des vignobles. L’étude a pour objectif d’identifié les zones potentielles pour la culture de la vigne et de cette façon orienté son élargissement avec le support des politiques d’état et pertinente assistance technique au producteurs de cette région.

This study of vitivinicultural zonation was carried out in the region of the Central Valley of Tarija (VCT), in the Department of Tarija, southern Bolivia, a region with more than 400 years wine tradition which actually presents a high quality. The valley has an area of total 332 thousand ha.; vineyards exist between 1660 and 2300 m.a.s.l. and in this altitude range there are 91 thousand hectares with a high potential for growing grapes. In the determination of homogeneous areas of the region, we considered the environmental aspects through satellite images, topographic maps, weather data and geology maps; thus the characteristics of the region for growing grapes were defined. Considering climate, we applied the Geoviticulture Multicriteria Climatic Classification System developed by Tonietto and Carbonneau (2004) which considers a heliothermal index (HI), dryness index (DI)) and a cold night index (CI), in this way there were 8 different types of climates identified throughout the region. For the characteristics of soil we determinated its morphology and did chemical and physical analysis, all dates were georeferenced. We realized a classification including the specific requirements and limits of grape plants to determine the aptitude of the soil. This study aims to identify areas with high potential for growing grapes and thus directing the growth of the sector, with support of state policies and suitable technical assistance to growers in the valley.

LC-HRMS data analysis of natural polymer homologue series Application on wine neutral oligosaccharides

Although oligosaccharides have much impact both on health (prevention of diabetes, cardiovascular disease), and on the perception of wine (sweetness, astringency, acidity or bitterness), information on their composition in wine is still limited.

EMERGENCE OF INORGANIC PHOSPHONATE RESIDUES IN GRAPEVINE PLANT PARTS, BERRIES AND WINES FROM SOURCES OTHER THAN FOLIAR SPRAYING

Inorganic phosphonates are known to effectively support the control of grapevine downy mildew in vi- ticulture. Their application helps the plant to induce an earlier and more effective pathogen defense. However, inorganic phosphonates have been banned in organic viticulture due to their classification as plant protection products since October 2013. Despite the ban, phosphonate has been recently detected in organic wines.

Chemical and sensory profile of Brazilian red wines upon the cultivar and geographic origin of vineyards

Many vineyards implanted in Brazil in the last 20 years are placed under very different natural conditions if compared to Serra Gaúcha, the oldest and more traditional viticultural region in the country.

Interaction among grapevine cultivars (Sangiovese, Cabernet-Sauvignon and Merlot) and site of cultivation in Bolgheri (Tuscany)

Different “landscape unit” have been identified in Bolgheri area (a viticultural appellation in the Tirrenian coast of Tuscany) by the aid of pedological, landscape and agronomic observations in the 1992-1993 period. In all cultivar (Sangiovese, Cabernet Sauvignon and Merlot) x landscape unit combinations, experimental plots were chosen in homogeneous vineyards, single cordon trained (about 3300-4500 vines/hectare). Grape maturation was studied by weekly samples of berries from veraison to vintage in the 1992-1995 period. At harvest yield and must composition traits were measured and, from the most représentative plots, sixty kilograms of grapes were harvested each year and vinified according to a standardised scheme. Wines were evaluated by standard chemical and sensory analyses.

Correlations between sensory characteristics and colloidal content in dry white wines

Must clarification is an important step occurring just after grape extraction in the elaboration of white wine, consisting in a solid-liquid separation. Traditionally, low must turbidity, around 50-150 NTU, is generally reached in white winemaking in order to prevent reductive aromas and facilitating alcoholic fermentation. Alternatively, a higher turbidity (300 NTU or above) can be sought for reasons such as a better expression of grapes identity (terroir), or for getting a must matrix that could supposedly lead to wines having greater ageing potential.
