My applied researches aim at helping winemakers to produce high quality wines. Main topics of investigation includes impacts of viticultural practices (nitrogen spraying at veraison, leaf removal, irrigation...) and enological techniques (fermentation conditions and yeast strains, maceration techniques) on wine aroma. Since 2011, my researches have been focusing on peppery aromas (rotundone) in red wines. These studies are carried out on Duras, Fer, Syrah and Gamay grape varieties.
