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.

What practices in the vineyard lead to the production of wines that consistently win medals?

High quality wines start in the vineyard however little is known about the role vineyard management practices play in this quality outcome. Gold medals and well-known regionality increase consumer preference for purchasing a wine. An increase in the former will certainly also drive an increase in the latter and therefore practices in production that consistently lead to gold medal winning wines will improve both the marketability of the region and its products. It is argued that vinification is the main driver of wine quality and in fact, the presence of some oak compounds is a well-known consumer and expert mark of quality. However, only select wines are vinified in oak and therefore the original grape quality at the winery door must in fact drive all further downstream vinification decisions.

Empreinte carbone et environnementale du vin en France : chiffres d’impact et bonnes pratiques à mettre en œuvre

Increasing concentrations of greenhouse gases (GHGs) in the atmosphere due to human activities are leading to a rise in the average temperature of the atmosphere. among the scenarios established by the un’s intergovernmental panel on climate change (IPCC), only two enable us to achieve the minimum objective of the paris agreements signed at cop 21 in 2015: staying below +2°c after 2050. both scenarios forecast a rapid reduction in GHG emissions as early as 2025, thanks to strong international cooperation, the priority given to sustainable development and responsible consumer choices.

HOW DO ROOTSTOCKS AFFECT CABERNET SAUVIGNON AROMATIC EXPRESSION?

Grape quality potential for wine production is strongly influenced by environmental parameters such as climate and agronomic factors such as rootstock. Several studies underline the effect of rootstock on vegetative growth of the scions [1] and on berry composition [2, 3] with an impact on wine quality. Rootstocks are promising agronomic tools for climate change adaptation and in most grape-growing regions the potential diversity of rootstocks is not fully used and only a few genotypes are planted. Little is known about the effect of rootstock genetic variability on the aromatic composition in wines; thus further investigations are needed.

Caractérisation du terroir en Espagne : méthodologie de l’évaluation et de la validation

In recent years, there has been a growing interest in characterizing the ecological environment of vineyard production, and the growing need to delimit and characterize with precision the different homogeneous viticultural units. This has allowed the development of new studies which have as their objective the Vineyard Zoning. The delimitation and characterization of wine-growing areas poses specific problems in Spain, not only linked to the specific characteristics of the territory, but also to the size, distribution and index of viticultural occupation in the designations of origin.
