Variabilité climatique et profils organoleptiques du Pinot noir dans le monde
2015
Wine typicity is revealed at various spatial scales, according to the variability of terroir components, which individual contribution change depending on the site. In this study, the impact of climate at global scale on the sensory profile of wine is examined.Thirty one Pinot noir wines produced in 16 winegrowing regions in Europe (Germany, France and Switzerland), North America (USA), South America (Chile) and Oceania (Australia and New Zealand) were selected. A blind testing was performed on the wines by 14 judges; among which 9 were considered sufficiently repeatable (criteria evaluated from the sensory analysis results of two identical wines). Wines were described by 26 visual, olfacto…

Contrôle des ravageurs de cultures par les ennemis naturels : la plante hôte facteur régulateur du système immunitaire des chenilles de vers de la gr…

10 pages; National audience; En raison des nombreux dégâts occasionnés par les vers de la grappe dans les vignobles, trouver un moyen de lutte efficace est devenu un réel challenge. A l’heure actuelle, la lutte biologique apparaît comme une alternative possible à la lutte chimique. Cependant, les résultats obtenus suite aux lâchers de parasitoïdes sont extrêmement variables dans leur efficacité. Des études approfondies de la biologie des vers de la grappe et de leurs parasitoïdes sont donc nécessaires afin d’affiner les méthodes de lutte biologique. Le système immunitaire des insectes représente la dernière ligne de défense des phytophages contre les parasitoïdes. Dans cette étude nous mett…
Effect of the host plant on the immunity of a phytophagous insect : influence of grape variety on the ability of the European grapevine moth to defen…
2013
In tritrophic interactions involving phytophagous insects, host plants and natural enemies, trophic levels are highly dependent on each other. Host plant may strongly affect directly phytophagous insect and indirectly natural enemies growing on these phytophagous insects. When a natural enemy attacks a phytophagous insect, the host immune system constitutes the last chance for the host to survive to an infection. A great variation of insect immune system is generally found in populations for susceptibility to pathogens, suggesting that variable selection pressures may have shaped and driven adaptation of immune traits. This project aims to determine the influence of both host plant and natu…
The "very loyal pinot": historical trajectory of a mythic grape variety of Burgundy
2019
Grape varieties began to appear in historical sources at the end of Middle Ages. In Burgundy, early mentions of pinot correspond to an evolution in the way wines were named. From the 14th century onwards, pinot wines have persistently demonstrated to express elements of superior quality. This variety is often offered at expensive prices due to the nature of its rarity, and as a result is commonly reserved explicity for the élites. However, it is suggested that the roles of The Dukes of Burgundy, concerning the promotion of grape varieties, is to be moderated. Therefore, if Philippe le Hardi’s proclamation condemns « the very bad and very disloyal plant called gaamez » then, it is evident th…
