French wine harvest forecast to hit 30-year

France's wine production is forecast to hit a 30-year low this year. The agriculture ministry's statistics body, Agreste, estimates a harvest of just under 34 million hectolitres following the country's hottest recorded summer.

Initial figures show a 6% drop from last year and a 17% decrease compared to the 2021-2025 average. Agreste reported that extreme weather was the primary cause, though a reduction in vineyard area also contributed.

Extreme Weather Impacts

The summer of 2026 was the hottest in France since records began in 1900. Average temperatures for June, July, and August reached 24C, with nearly half the country hitting 40C or above. "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," Agreste stated. This followed heavy spring rains that had initially encouraged growth.

Regional Disparities in Losses

Harvest losses vary severely across France's wine regions. Agreste's estimates show some areas were hit much harder than others.

Winemakers in Bordeaux, Languedoc-Roussillon, and parts of the south reported higher harvests than in 2025. However, all regions except Savoie remained below their recent five-year average.

Industry Disputes and Uncertainty

Some winemakers challenge the government's bleak figures. Cécile Mathiaud of the Burgundy wine producers association expressed surprise. "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," she said. Mathiaud noted variability within Burgundy and questioned the ministry's methodology, comparing this year to the historically low 2021 harvest of 1 million hectolitres. Agreste acknowledged its figures are preliminary estimates, with definitive results due later this year.

Climate and Additional Pressures

The climate emergency is shifting harvest patterns. For four decades, harvest dates have crept earlier. This year's timetable advanced by at least a week nationally, with some Bordeaux vineyards starting two weeks early. Wildfires posed another threat. While no major Bordeaux vineyards suffered direct fire damage, smoke from blazes within 15km of the city raised concerns about "smoke taint" affecting grape taste. The high uncertainty from weather and fires led the ministry to delay its initial forecast.

The sector faces broader challenges beyond the weather. Domestic wine consumption in France has plummeted from 127 litres per person annually in the 1960s to 40 litres now. Export demand is also down, with declining consumption in the key US market and wines impacted by tariffs imposed during the Trump administration.

Harvesting continues in some regions, and final figures await official declarations.
