In the second episode dedicated to Cotes du Rhone’s, we explore the sustainability program and the research that is taking place, other geeky episode just what we like!

Inter Rhône has three main missions: economic support, promotion of the appellations, and technical support. The latter is embodied by the ‘Institut Rhodanien’, where all our Research & Development is being carried I spoke to Julie Coutton, Intern Rhone, public relations manager to discover what research is taking place in the region.

Wine sustainability refers to a range of vineyard and wine production practices that are ecologically sound, economically viable, and socially responsible. Sustainable farmers may be certified (organic or biodynamic) or non-certified. Every vineyard site is different to get the best results in the bottle. Producers make decisions around certification based on how best to make their wine given the soil, climate and surroundings.

Converting a site to fully organic and biodynamic also needs to be done in stages over time so the land gets used to new practices. We talked with Julie about how the region is looking to mitigate the stress from drought, a tool for estimating water stress in the vineyard is the apex method. Based on the observation of the end of the branches, it is a simple method, which characterizes a growth dynamic, itself linked to the water constraint of the vine. It is to be carried out regularly, on a weekly basis.

Extensive research into new varieties is being conducted at the ‘Institut Rhodanien.’ Recently, four varieties have been accepted for experimental authorisation for Côtes du Rhône AOC due to their “adaptation to drought and late maturity.” These are white hybrid Floréal, Rolle (Vermentino), indigenous Carignan Blanc, and red hybrid Vidoc.


Other, topics that were part of the conversation are the study of sites and rootstock research, and winemaking practices to be more energy efficient. Intern Rhone holds talks and seminar for its member ensuring that they are always up to date to their scientific research Remember to subscribe and leave a review if you find this episode valuable to you!
