Valorisation agroviticole de l’effet terroir par l’enherbement des sols

Abstract

Les études développées par l’INRA et l’UV, à Angers, concerne les terroirs viticoles et leur gestion optimisée, tant du point de vue agroviticole qu’oenologique. Les travaux antérieurs (Morlat, 1989) ont permis de donner une dimension scientifique au concept de terroir viticole et ont démontré l’influence considérable de ce facteur de production sur la qualité et la typicité des vins (Asselin et al, 1992). Une méthodologie de caractérisation intégrée des terroirs, s’appuyant sur « l’Unité Naturelle Terroir de Base » (considérée comme la plus petite unité spatiale de territoire utilisable dans la pratique, et dans laquelle la réponse de la vigne est homogène), a été mise au point (Riou et al, 1995).

Les terroirs identifiés et cartographiés selon cette méthode occupent une surface qui varie de quelques hectares à plusieurs centaines d’hectares. Ils peuvent constituer la base d’un zonage pour une région viticole, à partir duquel on peut envisager d’une part, une utilisation rationnelle de l’effet terroir à l’échelle de l’exploitation viticole, et d’autre part une gestion parcellaire des itinéraires techniques.

Caractérisation et gestion de la maturation par terroir en Champagne

Pour prévoir et gérer chaque année les principales caractéristiques de la maturation en Champagne, le CIVC (Comité Interprofessionnel du Vin de Champagne) a développé un ensemble de moyens de prévision et d’information très performants qui permettent aux différents acteurs de la filière viti-vinicole de prendre en compte ces informations à l’échelle de chaque terroir communal pour la recherche d’une qualité optimale.

Non-Saccharomyces yeast nitrogen consumption and metabolite production during wine fermentation

Over the last decade, the use of non-Saccharomyces yeasts in the winemaking process has been re-assessed and accepted by winemakers. These yeasts can be used to achieve specific objectives such as lowering the ethanol content, preventing wine spoilage and increasing the production of specific aroma compounds. Since these species are unable to complete alcoholic fermentation, strategies of co- and sequential inoculation of non-Saccharomyces and Saccharomyces cerevisiae have been developed. However, when mixed starter cultures are used, several parameters (e.g. strain yeast, inoculation timing and nutrient competitions) impact the growth of the individual yeasts, the fermentation kinetics and the metabolites/aroma production. In particular, competition for nitrogen compounds could have a major impact, potentially leading to sluggish fermentation when the yeast assimilable nitrogen (YAN) availability is low. Moreover, many aroma compounds produced by the yeasts are directly produced and influenced by nitrogen metabolism such as higher alcohols, acetate esters and ethyl esters which participate in the organoleptic complexity of wine.

The colour pattern of flower arrangements influence wine tasters’ sensory description

The arrangements of flowers and wine counterparts are inextricably linked. Whether a fundamental aspect of tablescaping or acolytes to broader entertainment rituals, they have an entangled history since ancient times. The aim of this contribution is to verify the influence of visually delicate and robust flower arrangements on individual description of wines. Changes in the sensory description of wines were investigated during subjects’ (thirty-two participants) exposure to three different conditions: the presence of delicate, robust, or totally absent flower arrangements.

Relationship between soil and grapevine variety in the wineyard of Jura: example for the “Trousseau” variety from the “Terroir” of Montigny-Lès-Arsures (France)

Seven plots located in the commune of Montigny-lès-Arsures (Jura, 39), planted with grapevine varieties Trousseau and Savagnin, were chosen for a study of soil pits and a distribution of major and trace chemical elements in soils and wines. It was shown that the mineral matrix of the soil reflects the geological substratum and the sub-surface alteration process, while the organic soil matrix depends on agro-viticultural practices.

The effect of water stress deficit on ‘Xynisteri’ grapes through systems biology approaches

Cyprus is one of the very few phyloxera-free areas worldwide where the vast majority of vines are own-rooted and non-irrigated. ‘Xynisteri’ is a predominant indigenous cultivar, particularly amenable to extreme conditions such as drought and hot climate, thus rendering it appropriate for marginal soils and adverse climatic conditions. In the current work, a comparative study between irrigated (irrigation initiated at BBCH 71) and non-irrigated vines was conducted.
