French wine harvest forecast at 30-year low

France's agriculture ministry forecasts the country's smallest wine harvest in three decades. Initial estimates project a yield of just under 34 million hectolitres following the hottest summer on record.

Agreste, the government's statistics body, reported the drop from last year and a decline from the recent five-year average is largely due to extreme weather. "The summer was particularly hot and dry: soil drought has intensified throughout the country and heatwaves have caused localised sun scald, scorching, defoliation, and wilting of the grapes, reducing harvest volumes," it stated. The forecast comes despite heavy, growth-encouraging spring rains.

Record heat and regional impacts

A series of heatwaves brought France's highest average summer temperatures since records began in 1900. Nearly half the country saw temperatures reach 40C or above. The extreme conditions have hit wine regions unevenly, creating what Agreste calls "significant regional disparities."

While areas like Bordeaux and Languedoc-Roussillon reported higher harvests than in 2025, most regions still fell below the 2021-2025 average. Only the Savoie region exceeded that benchmark.

Industry disputes and uncertainty

Some winemakers challenge the government's bleak figures. Cécile Mathiaud of the Burgundy wine producers association expressed surprise at the "disastrous" forecast for her region. "We know we won't have a full harvest this year, but we have no definite figures and there's no suggestion the situation is a disaster," Mathiaud said. She noted some vineyards reported better-than-expected yields and questioned the ministry's methodology.

Agreste acknowledges its numbers are preliminary estimates. Definitive results will come only after official regional harvest declarations later this year. The ministry had even postponed its initial forecast due to "the high level of uncertainty" caused by weather and wildfires.

Climate shifts and additional threats

The climate emergency is visibly altering French viticulture. Harvests have traditionally occurred between September and mid-October, but for four decades the timetable has crept earlier. This year's harvest began at least a week earlier than last year nationwide, with some Bordeaux vineyards starting two weeks early.

Beyond heat and drought, wildfires pose a secondary threat. While no major Bordeaux vineyards suffered direct fire damage, winemakers fear smoke has tainted grapes near blazes that came within 15km of the city. This "smoke taint" can affect the taste of the finished wine.

The sector faces concurrent market pressures. Domestic wine consumption in France has plummeted from 127 litres per person annually in the 1960s to 40 litres now. Export demand has also fallen, with US consumption dropping and tariffs affecting trade.
