Résumé
Avant-garde and sensitive to the environment, Gérard Bertrand has been involved inconverting his wine estates into cultural practices and biodynamics, making himself a referencein terms of quality wines from La Clape.In order to satisfy the Demeter charter, a study has been launched to set up a protocol forthe development of starters and thus secure all the alcoholic and malolactic fermentationsduring the vinification of Château l'Hospitalet.Kinetic monitoring of fermentations, must analysis reports, as well as microbial analyzesin CMF will make it possible to probe the environment and the yeast richness which are at theorigin of spontaneous vinifications. In addition, a discriminative tasting will make it possibleto claim the expression of the Terroirs resulting from these fermentations.This work is part of a project that aims at studying indigenous environments and theirimpact on the organoleptic expression of the final wines and will outline a first step in thisstudy.
