Variabilité spatiale du gel printanier dans le vignoble champenois : application au zonage climatique

The purpose of the study was to monitor berry development as a function of site, vine water status and climate in order to improve our understanding of the role played by climate change on secondary metabolites relevant to wine quality.

The accurate estimation of yield is a fundamental for suitable viticulture, playing a pivotal role in the planning of logistics, the allocation of resources and the formulation of commercial strategies.

Managing pests in vineyards presents a major challenge for winegrowers, who are seeking effective solutions to control diseases and pests.

High-power ultrasounds have been related to an accelerated aging of wines, an effect that has been associated to the formation of radical species caused by the cavitation phenomenon [1]. This phenomenon consists of the formation of bubbles in the liquid medium that, when they collapse, cause high-pressure hot spots and temperatures of up to 4800 k [2], notably increasing the reactivity in the medium.

The knowledge about the molecular fraction associated to white wines oxidative stability is still poorly understood.
