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.

Sensory characterisation and consumer perspectives of Australian Cabernet Sauvignon wine typicity

Aim: To identify the sensory attributes responsible for the typicity of Cabernet Sauvignon wines from three Australian Geographical Indications (GIs) and to explore consumer purchase behaviour and preference with regard to regional wines.

INFLUENCE OF THE THICKNESS OF OAK ALTERNATIVES ON THE COMPOSITION AND QUALITY OF RED WINES

Aging red wines in oak barrels is an expensive and laborious process that can only be applied to wines with a certain added value. For this reason, the use of oak alternatives coupled with micro-oxygenation has progressively increased over recent years, because it can reproduce the processes taking place in the barrels more economically and quickly [1]. Several studies have explored how oak alternatives [2-5] can contribute to wine composition and quality but little is known about the influence of their thickness.

Valorization of wine lees for oenological interest by eco-responsible processes

Wine lees are the second most important wine by-product in terms of quantity after grape stalk and marc. During aging on lees, it is well known that wine lees yield compounds that act as antioxydant. However the chemical nature of the compounds involved in this behavior (except polyphenols and glutathione) has not yet been totally elucidated. The scarce knowledge of wine lees composition and their potential exploitation make them a promising candidate to obtain new antioxidant products to be used in winemaking. In this study, an eco-sustainable approach to obtain lees extracts exhibiting antioxidant capacity is proposed. Such extracts could be used in a global enological strategy of sulfites level reduction.

Il vino nobile di Montepulciano

C’è grande attenzione al rapporto tra zonazione e marketing. Mi sembra però che ci sia anco­ra oggi un salto fra le pratiche di analisi del terreno e di deterrninazione di quello che potremo definire “cru” e quello che può essere la sua utilizzazione rispetto ai consumatori finali.

Dynamics of soil and canopy temperature: a conceptual approach for Alentejo vineyards

Climate change imposes increasing restrictions and risks to Mediterranean viticulture. Extreme heat and drought stress events are becoming more frequent which puts in risk sustainability of Mediterranean viticulture. Moreover row crops e.g. grapevine for wine, are increasingly prone to the impact of more intense/longer exposure time to heat stress. The amplified effects of soil surface energy reflectance and conductance on soil-atmosphere heat fluxes can be harmful for leaf and berry physiology.
