Viticultural zoning of the country of Mendoza, Argentina. Study of the first zone : department of Luján de Cuyo. Statement of the study year 2002

Abstract

[English version below]

La région viticole de Mendoza est la principale zone vitivinicole d’Argentine qui se compose de 3 oasis (Nord, Valle de Uco, Sud). La première zone vitivinicole, située dans l’oasis Nord, est composée par les département de Luján de Cuyo et Maipu. C’est la zone de production la plus ancienne et la plus reconnue pour la qualité de sa production. Ce travail se porte plus particulièrement sur le département de Luján de Cuyo qui constitue le lieu traditionnel de production du Malbec argertin. Ce travail propose de caractériser les terroirs et de mettre en avant leurs typicités. Le croisement des informations climatiques et des analyses des sols est à l’origine d’un zonage agro-écologique réalisé antérieurement, ces zones seront précisées dans cette étude et seront définies comme des Unités Terroirs de Base (UTB). La mise en place d’un réseau de 14 parcelles d’observation composées de la même variété de référence le Malbec, permet l’étude du potentiel vitivinicole de cette zone. A la suite d’une première année d’étude, les zones homogènes ont pu être précisées et caractérisées du point de vue du comportement de la plante et de la typicité des vins. Ce travail sera poursuivi dans les années à venir pour confirmer les résultats et donner des réponses aux producteurs.

Mendoza is the most important wine producing province of Argentina. It is composed of three cases (Oasis Norte, Oasis Valle de Uco, Oasis Sur). The main wine producing zone is located in the “North Oasis” and is composed of the departments of Luján de Cuyo and Maipu. It is the oldest and the most well known zone for its quality of produce. This study focuses on the department of Luján, which is the traditional vine growing production area for the argentine Malbec variety. The aim of this study is to characterise the different “terroirs” and to point out their typicities. The interaction between climatic information and soil analysis had allowed to realise a agronomic and ecological zonation in a previous work. The zones which had been defined will be precise in this study and will constitute the “Basic Units of Terroir” (UTB). Within these units a net of fourteen vineyards were elected. All of them present the same reference variety : Malbec, in order to study the viticulture capacity of this zone. Homogeneous zones have yet been located and characterised according to the plant behaviour and the typicity of wines. Further studies are foreseen, so that the results can be verified and can help the productors.

Vegetative dose heights ‘Cabernet Sauvignon’ and its influence on fruit and wine quality

The leaf area is of fundamental importance so that the plant can realize adequate levels of photosynthesis for the accumulation of reserves and to reach a suitable maturation of the berries. In this sense, the objective was to evaluate the effect of different lengths of the stalks from the first support wire, in the must and in the wine of ‘Cabernet Sauvignon’.

Cépage “Baga” région Bairrada. 2- De la conduite traditionnelle jusqu’au système ‘Lys’

Pedological criteria according to the French hierarchy of vintages, Appellations d’Origine Contrôlée (AOC): study of two toposequences located in the Burgundian “Côte”

The concept of terroir is defined by a set of natural and human factors. On the slopy vineyards of the Burgundian « Côte », the « Appellations d’Origine Contrôlée (AOC) » spread out according to the slope in their order of quality : « AOC Grand Cru » at the top, « AOC Premier Cru » and « AOC Village » and « Bourgogne » on the piemont. In order to correlate the hierarchy of the vintages with the evolution of the topographic and pedological criteria, two toposequences were studied, in Gevrey Chambertin (« Côte de Nuits ») and Aloxe Corton (« Côte de Beaune »).

How to improve the mouthfeel of wines obtained by excessive tannin extraction

Red wines felt as astringent and bitter generally show high content of tannins due to grape phenolic compounds’ extraction in the maceration process. Among different enological practices, mannoproteins have been shown to improve the mouthfeel of red wines (1) and the color (2,3). In this work, we evaluated the effect of mannoproteins on the mouthfeel profile of Sangiovese wines obtained by excessive tannin extraction.

Construction of a 3D vineyard model using very high resolution airborne images

In recent years there has been a growth in interest and number of research studies regarding the application of remote optical and thermal sensing by unmanned aerial vehicle (UAV) in agriculture and viticulture. Many papers report on the use of images to map or estimate the growth and water status of plants, or the heterogeneity of different parcels. Most often, NDVI or other similar indices are used.
