France wine production faces historic lows due to heatwaves

French wine production is projected to reach one of its lowest levels in decades, with estimates from the agricultural statistics agency Agreste suggesting a total output of approximately 33.8 to 33.9 million hectolitres. This represents a 6% decrease from 2025 and a 17% drop compared to the 2021–2025 average.

The decline is attributed to a combination of shrinking vineyard surfaces—partly due to government-supported uprooting programs—and severe weather conditions. A particularly hot and dry summer, characterized by heatwaves and drought, has caused significant damage to grapes, including sunscald, wilting, and defoliation.

Regional impacts vary significantly:

• Champagne: Output is expected to plummet by nearly 50% compared to 2025. Despite the low volume, the Comité Champagne noted that the grapes harvested are of “outstanding quality.” • Bourgogne-Beaujolais: Production is forecast to drop by roughly one-third. • Val de Loire: Yields are expected to decrease by approximately 12%.

While some regions like Languedoc-Roussillon may see slight increases due to better yields, the overall national trend reflects a challenging period for the industry, marked by extreme climate volatility and shifting market demands.
