The role of vine trunk height in delaying grape ripening: insights for viticultural adaptation strategies

Context of the study. Shifts in grapevine phenology driven by temperature increase due to climate change may result in different rainfall profiles between phenological stages.

Soil salinity is an increasingly critical challenge for grapevine production, particularly in Mediterranean climates like California. Chloride (Cl-) accumulation, in particular, severely impacts vine growth, productivity, and fruit quality.

The vocabulary used to describe wine aroma is commonly organized according to color, raising the question of whether they reflect the reality of olfactory perception. Previous studies have assumed this convention of color-aroma matching, and have investigated color’s influence on the perception of aroma only in dyed white wine or in red wine from particular places of origin. Here 48 white and red varietal wines from around the world were evaluated in black glasses then in clear glasses by a panel of wine experts, who gave intensity ratings for aroma attributes commonly used by wine professionals. In black glasses, aromas conventionally associated with white wine were perceived in the red wines, and vice versa.

The exploitation of food by-products has garnered significant attention over the past few decades, particularly within the framework of the European Green Deal.

Aim: The notion of “terroir” enables the attribution of distinctive characteristics to wines from the same region. Climate change raises issues about viticulture, especially the growth of the vines and even more importantly the economic situation of actual wine-growing regions (Schultz and Jones 2010; Quénol 2014). Several studies have addressed the impacts of climate change on viticulture in
