Winter physiology in a warmer world: Cold hardiness and deacclimation sensitivity drive variation in spring phenology

In greenhouse, emission of volatile organic compounds (VOC) by grapevine leaves has already been reported in response to the defence elicitor sulfated laminarin (PS3) [1]. In order to check that this response was not specific to PS3, experiments were conducted on Vitis cv Marselan plantlets with several other elicitors of different chemical structures: i.e. Bastid® (COS-OGA),

During ageing, different chemical reactions occur affecting the stability of wine. These reactions depend on the temperature, the conservation time, etc. Also, these reactions are affected by dissolved oxygen (OD) and headspace oxygen (OHS) which are related to the permeability of different closures types.

The prospective study of the French wine sector (Sebillotte et al., 2004) has identified “groups of micro-scenarios” at the end of the analysis of the characteristics of this wine sector.

On assiste actuellement à l’émergence d’une demande sociale forte à l’égard de fonctions par ailleurs traditionnelles de l’agriculture, qui concernent la gestion des ressources du milieu, le maintien d’un tissu social rural, la valorisation des territoires ruraux et l’entretien des paysages.

The wine sector generates a considerable amount of wealth but is facing a growing problem of fraud. Wine counterfeiting is one of the oldest and most common cases of food fraud worldwide. Therefore, the authenticity and traceability of wine are major concerns for both the industry and consumers. To address these issues, robust and reliable analysis and control methods are necessary. Several methods have been developed, ranging from simple organoleptic tests to more advanced methodologies such as isotopic techniques or residual radioactivity measurements.
