France forecasts 33.9 million hectolitres of wine, a 30-year low

France is on course for one of its smallest wine harvests in 30 years. Agreste, the statistics arm of the agriculture ministry, estimated output on 7 September at 33.9 million hectolitres, about 4.5 billion standard bottles. That is 6 percent below 2025 and 17 percent below the 2021-2025 average. If the figure holds, the International Organisation of Vine and Wine series would make it the weakest year since 1957.

A hectolitre is 100 litres, or 133 bottles of 75 centilitres. The drop is the third thin harvest in a row. Agreste said vineyard area has shrunk and that the summer was hot and dry. Soil drought intensified across the country. Heatwaves scorched leaves and grapes, wilted bunches and cut yields. Almost half of France recorded 40C or more.

The regional split is wide. Champagne, which started picking in mid-August, is forecast 49 percent below 2025 and 47 percent below the five-year average. Cluster weights there are the lowest in 20 years. Bourgogne-Beaujolais is down by about a third. Pinot noir in Burgundy is on course for losses above 50 percent. The Jura is estimated 37 percent lower. The Loire is 12 percent below 2025 and 18 percent below the five-year mean, with young vines in Loire-Atlantique hit hardest. Charentes is down about 6 percent.

Languedoc-Roussillon, the largest volume region, should rise 5 percent from a weak 2025, though it remains below average. Bordeaux is expected to rebound 10 percent after late-August rain, and still sit well under its five-year mark. Savoie is one of the few areas not below that average. Harvests have started early across much of Europe.

Growers are also pulling vines under official grubbing schemes, which reduces the area that can recover when the weather turns. U.S. tariffs and weaker drinking at home add a demand problem to the supply shock. Champagne houses that already rationed allocations after short years now face a crop that is half last year’s. Prices for the remaining bottles will rise. Some domaines will not have enough stock to hold their usual export lists.

Agreste’s number is an estimate dated 1 September. Final volumes will move if September rain helps or if more bunches are rejected at the press. The direction is already clear. France is the world’s second wine producer after Italy. A third short vintage in three years is no longer a weather footnote. It is a structural cut in what the country can bottle.
