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.

Grafting, the most sustainable way to control phylloxera over 150 years

Just over 150 years ago, phylloxera, daktulosphaera vitifoliae, was introduced to europe, and particularly france, from north america via imports of american vitis plants. This aphid, with its complex biology and life cycle, has spread rapidly to most vineyards, causing rapid and lethal decline of v. Vinifera vines due to the primary and secondary damage it causes to the roots. In response to this pest, and given the economic importance of the french wine sector, professional representatives organised into ‘agricultural societies’, scientists and public authorities rallied together to identify the exact causes, seek solutions and try to stem the serious socio-economic crisis that ensued.
