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.

Effects of severe shoot trimming at different phenological stages on the composition of Merlot grapes

High concentration of sugars in grapes and alcohols in wines is one of the consequences of climate change on viticulture production in several wine regions. One of the options to alleviate this potential problem is to perform severe shoot trimming of the vines to limit the production of carbohydrates. Two different studies were performed in order to investigate the effects of severe shoot trimming on the composition of Merlot grapes; in a first study severe shoot trimming was performed at three different phenological stages (at berry set, at the beginning of veraison and at the end of veraison), while in a second study two trimming treatments (standard shoot trimming and severe shoot trimming performed at the end of veraison) were combined with two shoot densities in order to evaluate the relative impact of these treatments on Merlot grape composition.

Cultures des vignobles en forte pente: possibilités de mécanisation. Effet de l’exposition et de l’orientation des rangs

Plus de la moitié du vignoble suisse (14’000 ha) est situé sur des coteaux en forte pente (> 30%). Dans certains vignobles, la pente naturelle du terrain a été réduite par la construction de terrasses soutenues par des murs.

From bush to glass: unlocking the potential of indigenous microbes in Australian wines

Global trends in the wine industry are changing, which is caused by consumer demands for aroma and flavour innovation. Producers in Australia, the sixth globally ranked wine producing country, are embracing this trend by exploring non-conventional yeast species to improve sensory qualities and achieve fermentation advantages.

Implementing VIS-NIR spectroscopy as a rapid and non-intrusive technique for assessing anthocyanin and phenolic concentrations in Vitis vinifera L. Grenache whole grape berries

Anthocyanins and phenolic compounds play a crucial role in winemaking, contributing to the profile, flavor, color, texture, and stability of wine. Grape clusters, specifically Vitis vinifera L. cv. Grenache, were handpicked from a commercial vineyard sited in Tudelilla, La Rioja, Spain (42°18′ 52.26″, Long. -2°7′ 59.15″, Alt. 582 m) on five distinct dates from veraison to harvest during the 2015 season. Non-contact spectral measurements were conducted on intact grape berries using a VIS-NIR spectrometer operating in the 570 – 1000 nm spectral range under controlled laboratory conditions, positioned at a distance of 25 cm from the berries. The quantification of 16 anthocyanins and phenols in 120 grape clusters was performed using HPLC, established as the reference method for validating the spectral tool.
