Record Heat Forces Winemakers in Southern France to Harvest Early

Perpignan – 05.08.2026: In the wine-growing areas of the Aude and Pyrénées-Orientales departments, exceptional heat has brought the grape harvest forward significantly. Grapes ripened so quickly this summer that numerous estates had to reorganize their harvest operations at short notice. Early-ripening varieties are already being picked, while winemakers are monitoring the development of their remaining plots every day.

Coastal sites and warm vineyards in Roussillon, as well as parts of the Corbières, have been particularly affected. Some estates had already begun harvesting in mid-July. According to industry sources, the harvest started at several wineries around a week earlier than usually expected, and in some places even earlier than during previous heatwave years.

High temperatures accelerate sugar accumulation in the berries, narrowing the window for harvesting. However, sugar content alone does not determine the ideal harvest day. Acidity, aromas and the condition of the grapes are equally important. If they remain on the vine too long, the freshness and balance of the resulting wines can suffer. Estates must therefore make decisions quickly without losing sight of the differing ripening patterns across their vineyards.

The earlier campaign is also changing work organization. Seasonal workers are needed sooner, and harvesting teams often start in the early morning because of the heat. In the Pyrénées-Orientales, some grape-harvest jobs had already been advertised from mid-August, while other estates had scheduled work to begin as early as late July. Dates vary considerably depending on grape variety, location and weather conditions.

Winemakers in southern France have been observing for years that vegetation begins earlier and the harvest calendar is shifting. Jean-Marie Fabre, a winemaker in Fitou in the Aude department and president of the association of independent winemakers, had already pointed to this long-term trend in July. An early harvest is therefore no longer an exceptional phenomenon. What is unusual this time is above all the speed at which many grapes have reached maturity.

For many wineries, the heat comes amid an already difficult economic situation. In Roussillon, drought and low yields have weighed on estates in recent years. An early start to harvesting does not necessarily mean a larger crop: water stress can result in smaller berries and lower juice yields.

Ripening can also vary considerably within a single estate. There can be several days or weeks between hot coastal sites and higher-elevation vineyards. While harvesting is already under way in some plots, other estates are preparing for further picking rounds. The size of the harvest and the quality achieved by the vintage can only be assessed after the harvest has been completed and the first wines have been matured.
