Data deluge: Opportunities, challenges, and lessons of big data in a multidisciplinary project

Grapevine trunk diseases (GTDs), caused by a group of fungal pathogens including Phaeomoniella chlamydospora, Phaeoacremonium minimum, and Diplodia seriata, pose a serious threat to grapevine cultivation worldwide.

This study evaluates the effect of different oenological factors and natural mediators on the degradation of Ochratoxin A (OTA) using Botrytis cinerea laccase.

Aroma and mouthfeel cues are the main characteristics defining red wine quality. During wine tasting, perceptual and physical-chemical phenomena leading to mutual interactions between volatiles and non-volatiles sensory active compounds, can occur. Aroma perception depends on the release of volatiles from wine, that is affected by wine constituents present in the medium (Pittari et al. 2021; Lyu et al. 2021). Our aim was to evaluate the effect of the non-volatile wine matrix composition (polyphenols, PPh) on the release and perception of red wine aromas by an experiment of matrix enrichment.

This study examines the different strategies adopted by wine exporters located in France for penetrating international alcohol distribution networks in the U.S. market (and to a lesser extent the Canadian market). Grounded in the Business-to-Business (B2B) marketing literature (Ellegaard and Medlin, 2018), this study adopts a framework integrating a ‘Stakeholder’ approach for understanding the logics behind exporters’ strategies to penetrate the alcohol distribution networks (wholesalers, importers, alcohol monopolies).

Vintage is part of « terroir ». The aim of this work is to study, through vine and berry parameters, the effect of vintage on the three major red grape varieties in Côtes du Rhône : Grenache N, Syrah N and Mourvedre N. We first characterized vintages 1997 to 2003, highlighting similar features in grape development across the different cultivars since 2001 only.
