Vintage influence on Grenache N, Syrah N and Mourvedre N in Côtes du Rhône (France)

Abstract

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. Then we showed that vintage becomes the major effect only if vine vigour is stabilized. Indeed, there is a strong relationship between an excess of vigour and berry size on Grenache and Mourvedre, whereas fertility of Syrah is reduced when vigour is decreased. This work has to be continued by integrating meteorological data, to explore more precisely the effect of vintage on vine and grape development.

Leveraging the grapevine drought response to increase vineyard sustainability

In this video recording of the IVES science meeting 2024, Silvina Dayer (PhD in Agronomy, Les Sanctuaires du Mirazur-Groupe Mauro Colagreco, Menton, France) speaks about grapevine drought response to increase vineyard sustainability. This presentation is based on an original article accessible for free on IVES Technical Reviews.

Fast, and full microbiological wine analysis using triple cellular staining.

We propose here a brand new large routine microbiological analysis method intended for oenology, in flow cytometry, using high performance equipment and triple selective cell staining, activated by fluorescence. The results and practical applications of the method are presented: Brettanomyces (Dekkera) Monitoring, fermentations monitoring, bottling and enological practices monitoring.The method allow a complete new microbiological tool for wine industry.The method has been accredited ISO 17025 in our laboratories.

Gevrey-Chambertin : les enjeux d’un territoire vitivinicole locale à l’échelle mondiale

An emblematic name of the burgundy wine region, a few kilometers from dijon, gevrey-chambertin stands out as a small wine town of international renown in the heart of a prestigious red wine vineyard listed as a unesco world heritage site.

Wine chemical markers assess nitrogen levels in original grape juice

Nitrogen (N) nutrition of the vineyard plays a crucial role in the composition of must and wine, impacting fermentation, as well as the aroma and taste of the final product. N-deficient grape juice can result in increased astringency and bitterness, and a decrease in pleasant aromas in the wine.

Deciphering the function and regulation of VviEPFL9 paralogs to modulate stomatal density in grapevine through New Genomic Techniques

Stomata are microscopic pores mainly located in leaf epidermis, allowing gas exchanges between plants and atmosphere. Stomatal initiation relies on the transcription factor SPEECHLESS which is mainly regulated by the MAP kinase cascade, in turn controlled by small signaling peptides, the Epidermal Patterning Factors (EPF and EPF-Like), namely EPF1, EPF2 and EPFL9. While EPF1 and EPF2 induce the inhibition of SPEECHLESS, their antagonist, EPFL9, stabilizes it, leading to stomatal formation. In grapevine, there are two paralogs for EPFL9, VviEPFL9-1 and VviEPFL9-2. Despite their structural similarity, it remains unclear whether they are differentially regulated and have distinct roles.
