How wildfires are scorching France’s wine industry

Key points

• This year's hot season began with a suffocating heat dome in May, and by mid-August, punishing temperatures reached 40 degrees Celsius (104 degrees Fahrenheit) in some areas.
• US President Donald Trump's tariffs on French wine in 2025, and repeated threats to hike the taxes, have not supported declining sales.
• In the southwest Gironde region alone, an area regarding four times the size of Paris was burned in the largest fire there since 1949.
• Although the fires reached within 15 kilometres (9 miles) of Bordeaux, most of the region's vineyards.
• This year, Western Europe endured one of its hottest summers, aggravated by the El Nino weather phenomenon.

As wildfires razed swaths of Western Europe this summer, wineries in the region have grown increasingly concerned regarding the fate of one of the area's most notable exports.

In France, Europe's largest wine exporter by far, some 739, 000 hectares (1.8 million acres) of land is dedicated to vineyards that sprawl throughout wine-making regions such as Languedoc, Bordeaux and the Rhone Valley. So has it been for centuries.

But now, human-induced climate change is causing more extreme weather conditions, threatening the precious and fragile grapes. It are particularly sensitive to heat. Worse, the frequency of wildfires in the tinder-dry forests is rising, causing havoc to agriculture.

This year, Western Europe endured one of its hottest summers, aggravated by the El Nino weather phenomenon. It is characterised by hotter, drier conditions. Europe is now the planet's fastest-warming continent, and in some places, is ill-equipped to accord with hot weather.

This year's hot season began with a suffocating heat dome in May, and by mid-August, punishing temperatures reached 40 degrees Celsius (104 degrees Fahrenheit) in some areas. Wildfires tore through areas of Gironde, southwestern France, close to Bordeaux and in the heart of wine country.

Higher temperatures force grapes to ripen much faster than normal. While that produces a more sugary flavour, it additionally affects the grape's natural acidity and pushes up alcohol content in the wine it produces.

With forests tinder-dry, destructive wildfires have additionally broken out at a scale never recorded before, including in wine country. Here's what we know. Where have wildfires occurred in France?

Notably, the 2026 wildfire season in southwest Europe has been one of the worst in decades, with a series of massive blazes recorded in France between June and July.

At least 465, 000 hectares (115, 000 acres) of land have been burned since the start of the year, Interior Minister Laurent Nunez remarked to journalists against the backdrop of the inferno in July.

In the southwest Gironde region alone, an area regarding four times the size of Paris was burned in the largest fire there since 1949. The department's capital is Bordeaux, one of the country's most significant wine-growing regions and home to numerous iconic French wines.

As the blazes engulfed the Gironde's vast pine forests, authorities introduced a massive evacuation effort, with some 220, 000 residents needing to leave their homes, including those living close to Bordeaux. The fires were so intense that they created lightning bolts and ignited even more flames.

As well as areas in the Aude and Herault regions have additionally been affected, southwestern Landes, Var.

By September 1, some small fires were still active in the south, including in Saumos, regarding an hour from Bordeaux, according to the monitoring website Feux de forets. All of the blazes are now under control. How are grape vines affected by fires?

Although the fires reached within 15 kilometres (9 miles) of Bordeaux, most of the region's vineyards. It are located further inland, have been largely untouched, Per Karlsson, a wine expert who runs a wine tour agency, BK Wine Tours, alongside his wife, informed Al Jazeera.

Nevertheless, some growers are at risk not from the fires, but from the smoke. That's since the wind can carry smoke and ash much farther than the fires themselves reach. As the fires were raging, Al Jazeera's Nina Montagu-Smith documented ash falling on the wine-region town of Libourne, more than 100km (62 miles) from the source of the fires on Cap Ferret, a narrow peninsula on France's Atlantic coast, west of Bordeaux, in July. Libourne is close to the significant wine centre of Saint-Emilion.

"When I visited Arcachon, a seaside town just throughout the bay from Cap Ferret, we could see the fires on the peninsula. Within hours, the sky had blackened, and the smoke was thick over Arcachon town, " Montagu-Smith remarked.

Meanwhile, the spreading smoke "may have caused a bit of 'smoke taint'", Karlsson explained.

Smoke can damage grapes by penetrating their skin and releasing a smoky flavour during fermentation. That affects the taste and aroma, and lowers the overall quality of the juice and resulting wine. Rinsing the grapes when absorption has already occurred does little to support, he went on.

Another matter is that wine tourism has been affected. Wineries view tourism as a significant extra source of revenue at a time when wine consumption is falling generally.

"Wine tourism is becoming a very important aspect of the industry, " Karlsson remarked. He and his wife organise private tasting trips to vineyards, including in Bordeaux and other parts of France.

"Large numbers of wineries in Bordeaux are open to it these days, although it used to be very hard to get into them, " he remarked.

Against the backdrop of the wildfires, tourists are worried concerning venturing into some areas, he continued. As the Gironde wildfire raged, the French administration additionally appealed to the public to avoid the region, in late July. What other challenges are winemakers facing?

Besides the wildfires and scorching heat, an ongoing drought in Western Europe is additionally affecting grape growers.

Critical water sources such as the Danube River and the Rhine have retreated drastically, affecting producers in a number of countries.

In eastern France, the Doubs River has all but vanished in some places, revealing parched riverbeds. Authorities have been forced to enforce water-use restrictions in plenty of areas. In July, France's Ecological Transition Minister Monique Barbut remarked at a crisis gathering that this year's drought was "exceptional" in its intensity, and had occurred despite average rainfall.

Grape-growing regions traditionally depend on rainfall since authorities have banned irrigation to force vines to seek groundwater naturally. As unregulated irrigation can cause grapes to absorb too much water, bloating the fruit and diluting the flavour of wine, the main reason for this was to ensure higher quality.

But vines need sufficient water to produce major, juicy berries. When vines don't obtain adequate water, they draw it from the grapes instead, causing the berries to shrink, experts say, during droughts.

Stephane Vignon, a winemaker in the village of Verzenay, northeastern France, informed Reuters that some bunches of grapes weighed almost 30 percent less than their typical weight this year.

As farmers feared losses from accelerated ripening and reduced acidity, the combined crises brought the harvest season in France forward to August this year, much earlier than the traditional September harvest time.

As globally, individuals are drinking less wine, compounding this, the wine industry in France is facing weaker sales due to shifting habits.

In the United States, the world's largest wine-drinking country and France's biggest buyer, wine consumption went from 3.3 billion litres (872 million gallons) in 2020 to 2.7 billion litres (717 million gallons) in 2024, according to the California-based Wine Institute.

"Climate change for the foreseeable future is manageable, " Karlsson observed, pointing out that grape growers are starting to adapt their farming behaviours by planting more tolerant grape varieties, for example. But fewer wine drinkers? "That's the bigger issue, " he concluded.

In short, how wildfires are scorching France's wine industry is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
