Today, the demand is oriented towards wines with fruity and floral sensory profiles. In order to meet consumer expectations, it is necessary to develop strategies to control the winemaking process to obtain the desired organoleptic properties. The general objective of this work is therefore to study the individual and combined effects of two key fermentation parameters on yeast metabolism and fermentation aroma synthesis: nitrogen and temperature. The first part of this thesis was devoted to studying the impact of the nitrogen addition timing during fermentation on the synthesis of aroma compounds by the yeast. In this sense, a study combining statistical modeling and analysis of the expression of genes involved in the aroma synthesis by ye...
