Eléments importants d’une méthodologie de caractérisation des facteurs naturels du terroir, en relation avec la réponse de la vigne à travers le vin

Abstract

The French viticultural appellation areas are the result of an empirical, historical and evolutionary selection which, generally, has consecrated a match between natural factors, grape varieties and viti-vinicultural practices. The notion of terroir is the main basis of the Appellation d’Origine Contrôlée in viticulture. It is based on the one hand on privileged natural factors and on the other hand on the know-how of the winegrowers; the whole allowing the production of a wine endowed with an authenticity and a sensory typicity. Wine-growing practices evolve according to progress in viticulture and oenology, while the natural factors of the terroir are much more stable, with the exception of the vintage. They therefore represent a fundamental pillar of the identity of an appellation vineyard. Faced with a wine market that is globalizing and an evolution of the consumer, the “terroir” factor takes on a new dimension, becoming an important commercial vector for many vineyards.

Scientific approaches to this theme have been relatively limited, due to the complexity of the problem concerning the variables to be studied, their chain of influence and the overall response of the vine to the terroir, through wine (Riou et al., 1995 ). An AOC most often applies to a wine-growing region whose surface area is sufficient for the expression, in most cases, of a large-scale spatial diversity of the natural environment (terroir units) which can lead to significant differences in the kind of wine..

An economic valuation of this factor of production therefore requires a method that can easily reveal and identify the units of terroir of a region, but also give them a spatial dimension, to allow a concrete use by the winegrowers, at the level of wine and agro-viticultural techniques.

Spatial characterization of land use in the viticultural Maipo Valley (Chile), using aster image digital processing

L’entreprise viticole Concha y Toro S.A. gère environ 600 ha de vignes dans la Vallée du Maipo (A.O. Valle del Maipo). L’objectif est celui de caractériser spatialement ces vignobles et leur occupation du sol environnante. Le choix s’est porté vers la démarche de zonage viticole par l’analyse spatiale, utilisant des traitements d’images satellitaires afin d’avoir une vision synoptique de la zone à moindres coûts et délais. Un système d’informations géographiques (SIG) est construit à partir des données suivantes : cartes topographiques, géologique, fond cadastral numérique, images satellitaires. Un modèle numérique de terrain est par ailleurs construit à une résolution de 25 m à partir des cartes topographiques.

High-altitude vineyards under extreme conditions in the PIWI context of cultivation: economic and marketing evidence from an exploratory study in Northern Italy

Viticulture has spread to unexpected locations, such as high-altitude terrain. Among these, high-altitude viticulture has captured considerable attention, not only for the uniqueness of its products and landscapes but also because it offers an effective response to climate changes
The aim of this study is to analyse and compare wineries that used Piwi varieties (acronym for the German Pilzwiderstandfähig, i.e., cryptogame-resistant) at high altitudes (between 500 and 920 m a.s.l.) with the traditional non-mountainous viticulture model.
