Influence on grape aroma of nitrogen compounds and elicitors foliar applications in vineyards

AIM: The grape volatile compounds determine the wine quality and typicity [1]. Thus, looking for agronomic tools to improve its composition it is of great interest in the sector [2]. The aim of this work was to study the effects of several foliar applications in Garnacha, Tempranillo, and Graciano grapevines in order to enhance their […]

Foliar application of specific inactivated yeast to enhance the varietal aroma precursors accumulation on cv. Traminer

AIM: The production of grapes with a balanced composition is one of the main goals that agronomists and oenologists pursue to produce premium quality wines. The gap between technological (sugar/acid ratio) and aromatic maturity is expanding due to the increasing temperature and lack of rainfall during the ripening phase. In three consecutive years 2017, 2018 […]

Temperature variability inside a wine production area and its effect on vine phenology and grape ripening. An example from the Saint-Emilion-Pomerol

AIM: the aim of this study was to develop a method for fine-scale temperature zoning. The effect of temperature variability on vine phenology and grape composition was assessed in the production area of Saint-Emilion, Pomerol and their satellite appellations (Bordeaux, France). METHODS: 90 temperature sensors were set up inside the vine canopy over an area […]
