Caractérisation et valorisation des terroirs de l’appellation d’origine contrôlée Puisseguin-Saint-Emilion

Abstract

Le terroir viticole, qui est la base de la délimitation des aires d’Appellation d’Origine Contrôlée, est une notion complexe dans laquelle sont en interaction la vigne, les facteurs naturels tels que le sol, le climat, ainsi que le facteur humain à travers les pratiques des viticulteurs. Le terroir conditionne la composition des raisins et ainsi la qualité et la typicité des vins qui en sont issus. Suite à la fusion du syndicat viticole de Puisseguin avec celui de Saint-Emilion pour former le Conseil des Vins de Saint-Emilion, et dans une démarche globale de connaissance et de valorisation de cette nouvelle entité géographique, une étude sur le secteur de l’AOC de Puisseguin a été menée. Une cartographie des sols au 1/25 000 décrivant les différentes unités pédologiques a été réalisée ainsi qu’une analyse du système de conduite. Dans chaque unité pédologique identifiée, une fosse a été décrite puis analysée, permettant de définir les principales caractéristiques agronomiques de ces sols. Des conseils adaptés à chaque unité sont proposés afin de mieux valoriser ces terroirs. Chaque viticulteur a ainsi pu bénéficier des résultats de cette étude à travers un manuel technique et des communications orales.

English version: Terroir which is the basis for the controlled origin of wines (“Appellation d’Origine Contrôlée”) is a very complex concept including the vine, climate, soil and human factors such as technical practices. Terroir plays a very important role in grape composition and in wine quality and typicity. Following to the merge of Puisseguin and Saint-Emilion winegrowers associations and in order to improve the knowledge and the valorization of this terroir, a study was carried out on the Puisseguin area. This study comprized an identification of pedological units through soil mapping at a scale of 1/25 000th and a survey of currently existing training systems. For each pedological unit, advices were formulated to improve terroir valorization. Moreover, every wine grower received these results through a technical manual and oral communications.

Cartography of « Terroir Units » is a Tool to Improve the Ré Island Vineyard Management (France)

A study of « terroirs » was achieved from 2003 to 2005 in the whole vineyard of the Ré island (17, France). Over more than 1,990 ha, a cartography at the 1/10.000 scale, including characterization of climatic, pedological, geological and hydrogeological components of « Basic Terroir Units » (B.T.U.) was made. Also, a survey among wine growers was conducted. All data were treated together in a G.I.S. connected to a data base. 22 kinds of map were built (B.T.U. and components, soil water reserve, vine functioning potentials, varieties, rootstocks, viticultural practices and soil management).

Acceptance of fungus-resistant grape varieties from the perspective of producers and consumers in Germany

Fungus-resistant grape varieties (frgv) are an important field of research in viticulture, as they represent a way of reducing the use of copper-containing pesticides and thus minimising the environmental impact. The literature suggests that resistant grape varieties are a promising solution to the problem of using copper-containing pesticides in viticulture and that their quality has improved in recent years. However, there are still challenges in the acceptance and dissemination of FRGV by wine producers and consumers.

Role of landscape diversity for biodiversity conservation in viticulture: life+ biodivine’s results

Nowadays biodiversity loss is considered as a prior environmental issue. Agricultural landscapes are particularly concerned, mainly through the specialization and intensification of farming activities which lead, at a larger scale, to landscape simplification. Landscape management would be a good means to halt biodiversity loss, but large-scale studies remain rare. The life+ project BioDiVine aims to understand biodiversity dynamics and promote sustainable conservation actions at this scale in viticulture.

Impact of malolactic fermentation on volatile composition and sensory properties of white and rosé wine from the greek variety moschofilero

Moschofilero is a native grape variety, classified as a ‘gris’ type variety, that is cultivated in PDO Mantineia, Peloponissos, Greece. It is used for the production of both white and rosé wines. Due to high altitude of the vineyards, the harvest is done by mid October, and many vintages are characterised by high acidities and low pH values.
