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.

Adaptation of Lactobacilli towards low ph and SO2 to develop MLF in base musts for sparkling wines

In some white wines, malolactic fermentation (MLF) is very interesting, and for low pH wines this process is particularly difficult. Although MLF is generally not recommended for sparkling white wine, some winemakers prefer to promote MLF to contribute to organoleptic complexity. Oenococcus oeni is generally the bacterium of choice for MLF.

The Douro region: wine and tourism

The Demarcated Douro Region (DDR) dates from 1756, when it was recognized as one of the first demarcated regions in the world. The DDR economic activities fit the terroir model and are based on wine and tourism.

Impact of non-fruity compounds on red wines fruity aromatic expression: the role of higher alcohols

A part, at least, of the fruity aroma of red wines is the consequence of perceptive interactions between various aromatic compounds, particularly ethyl esters and acetates, which may contribute to the perception of fruity aromas, specifically thanks to synergistic effects.1,2 The question of the indirect impact of non-fruity compounds on this particular aromatic expression has not yet been widely investigated. Among these compounds higher alcohols (HA) represent the main group, from a quantitative standpoint, of volatiles in many alcoholic beverages. Moreover, some bibliographic data suggested their contribution to the aromatic complexity by either increasing or masking flavors of wine, depending of their concentrations.

Application de l’Analyse du Cycle de Vie (ACV) à un domaine viticole

Since 1980, Château de l’Éclair has belonged to SICAREX Beaujolais and has been involved in experimentation for the Beaujolais vineyards. However, it is a commercial estate with profitability and quality constraints, which means that it has to meet the growing environmental expectations of consumers. Given the number of practices claimed to be environment-friendly, it is sometimes difficult to prioritize actions.

Phenological characterization of a wide range of Vitis Vinifera varieties

In order to study the impact of climate change on Bordeaux grape varieties and to assess the adaptation capacities of candidates to the grape varieties of this wine region to the new climatic conditions, an experimental block design composed of 52 grape varieties was set up in 2009 at the INRAE Bordeaux Aquitaine center. Among the many parameters studied, the three main phenological stages of the vine (budburst, flowering and veraison) have been closely monitored since 2012. Observations for each year, stage and variety were carried out on four independent replicates. Precocity indices have been calculated from the data obtained over the 2012-2021 period (Barbeau et al. 1998). This work allowed to group the phenological behaviour of the grapevine varieties, not only based on the timing of the subsequent developmental stages, but also on the overall precocity of the cycle and the total length of the cycle between budburst and veraison. Results regarding the variability observed among the different grape varieties for these phenological stages are presented as heat maps.
