Les vins AOC Bordeaux préparent l’arrivée des cépages résistants
The regional appellation anticipates the European authorization to claim hybrid varieties as PDO, including those that can drastically reduce phytochemicals against mildew and powdery mildew.
R
met on February 8, the board of directors of the Bordeaux appellation validated the possibility of integrating resistant grape varieties on an experimental basis into its specifications. Registered as Varieties of Interest at the End of Adaptation (VIFA), these vines recognized as AOP for 10 years could not exceed 5% of the surface area of the required estates, for wines not exceeding 10% of the blend. recalls Stéphane Gabard, president of the Defense and Management Organization (ODG).
Anticipating the future Common Agricultural Policy (PAC 2023-2027), which will allow the integration of grape varieties that are not 100% Vitis vinifera in the AOP specifications, the Girondine appellation is getting ready to register hybrid varieties as soon as possible, combining the organoleptic characteristics of traditional grape varieties with the genes for resistance to mildew and powdery mildew from wild vines. It must be said that after a trying 2021 vintage (with trying mildew pressure), the prospect of only treating two to three times a year can only be appealing. Beyond the decrease in the Treatment Frequency Indices (IFT), these resistant grape varieties also make it possible to solve the impasses linked to the Non-Treatment Zones (ZNT, whether they are local residents, waterways, etc.) .
With plans to make rapid progress on these environmental VIFAs, ODG Bordeaux already has experience with climatic VIFAs, having registered six more southern grape varieties to adapt to new conditions, particularly water conditions. Wishing to give a vision of the future to the Bordeaux vineyards, Stéphane Gabard envisages rapid progress. And new plantations of grape varieties before the change in specifications, these plots currently only being able to produce wine without geographical indication (VSIG) could become PDO (if they choose the grape varieties of interest and cultural conditions meeting the specifications). charges). For the climatic VIFAs, three plots of marselan and arinornoa have thus been validated in AOP from 2022.
Due to go this Friday, March 4, the general assembly of the ODG must decide on this project to change the specifications.
