Rhône North: 2025 vintage, historic or climate turning point?
The year 2025 will leave a strong mark on the memory of the winegrowers of the Valley of Rhône northern. It embodies both the harshness of the climate and the remarkable adaptability of the vineyard. Two heatwaves, in June and then in August, punctuated the season, the second proving particularly devastating.

While the vines had managed to withstand the first heatwave in June, thanks to a generously wet winter and spring, the August heatwave put them to a severe test. "There was sufficient water reserves to cushion the blow in June," explains Cyril Courvoisier, President of the appellation Cornas, "but the week with temperatures exceeding forty degrees in August created very contrasting situations depending on the altitude and exposure of the hillsides."
Then, towards the end of August, moderate rains came to relieve the vines and give them a bit of a boost. It was in this context that the harvest began at exceptionally early dates, as in the Maison Mr. Chapoutier, who made the first cuts with pruning shears on August 14th on his plots in Saint-Péray.
Promising balances despite declining volumes.
Volumes are expected to be down. The poor grape set, observed as early as May, had already alerted winegrowers even before the heatwave. The heat stress only exacerbated this deficit, which was further aggravated locally by pressure from… game.
Yet, the quality seems to be there. The grapes were in exemplary condition, and the first tastings at the end of fermentation suggest concentrated and balanced wines. "It's sunny, intensely colored, concentrated in tannins, but without excess," emphasizes Cyril Courvoisier. "We've preserved beautiful acidity and a fine, elegant tannic structure." This reflects both the winemakers' accumulated experience in dealing with extreme weather and the richness of the vintage.

Towards a new era of adaptation
With a summer ranked among the three hottest ever recorded in France, 2025 marks a turning point for viticulture. As Cyril Courvoisier points out, "these phenomena are incredibly violent and rapid, exceeding the pace of a generation of winemakers." According to him, it's difficult to identify a general trend, other than one of extremes: "Since 2021, the region has gone from a scorching vintage to a rainy one, from severe frost to record-breaking heat."
Despite the challenges of the 2025 vintage, the vines, like the winemakers, are demonstrating remarkable resilience. Thanks to a better understanding of the terroirs and increasingly refined practices, the Valley of Rhône Septentrionale demonstrates its ability to transform these trials into learning experiences and to build, vintage after vintage, the foundations of a more adaptable viticulture.
