As wildfires continue to blaze near Bordeaux, in what President Emmanuel Macron has described as the toughest situation France has faced since World War II, the country’s celebrated wine region confronts a growing environmental crisis.
Thousands of firefighters are working around the clock to contain one of the largest fires in modern French history in the Gironde region, home to many of the many famed vineyards of Bordeaux.
The blazes have forced more than 220,000 people to evacuate across France and destroyed around 240 homes, according to officials. Of this number, around 4,000 people have also been evacuated from tourist hotspots along France’s Atlantic coast, including campsites and holiday villages.
The French government has urged tourists to avoid the Bordeaux area, dealing a fresh blow to the region’s tourism industry at the height of the summer season. The timing could hardly be worse for Bordeaux’s wine sector, adding to challenges it is currently facing – from falling consumption to wider economic pressures.
Wine tourism was a bright spot, but now, the wildfires have pulled the stops on the growing sector. “Tourism was really the only dynamic part of the business that was still growing, both for us and, more generally, for Bordeaux wines,” winemaker Edouard Le Grix de la Salle told The Independent. “And now this comes along as a brake.”
Le Grix de la Salle criticised the authorities for failing to better protect one of the region’s most valuable industries.
“How did they not think about protecting that sector? And the cultural sector, too. There’s so much to visit in Bordeaux. There are so many museums, there are châteaux. It’s unbelievable,” he said.
Peggy Plouhinec, general director of Château Picque Caillou, one of the few wine estates on Bordeaux’s western side, added that her estate had temporarily closed because of heavy smoke.
“The hospitality sector will be impacted this summer, that’s for sure,” she told BBC. “What is happening is unprecedented. We’re lucky that we haven’t been too affected yet, but the business will still suffer from the lower numbers of tourists.”
She said conditions had improved following rainfall on Sunday night,
Climate pressures mount
While vineyard owners say most vines have evaded direct damage from the flames, the fires have intensified concerns about the long-term effects of climate change on Bordeaux’s vineyards.
The region has endured months of intense heat and severe drought, leaving vegetation tinder dry and fuelling the spread of wildfires while placing vineyards under increasing water stress.
In Margaux, where some of Bordeaux’s most prestigious wines are produced, vines remain intact and wine quality is not currently expected to suffer as a direct result of the fires, according to Thomas Duroux, director general of Château Palmer.
However, he warned that this year’s conditions marked a turning point.
“What we are experiencing this year is a wake-up call. We are facing something we have never seen before. We not only have to limit the damage, but also look to the future,” he said.
“Our priorities today are water resources – because without water we will no longer be able to plant vines in conditions like these – and adapting our vineyard so it becomes more resilient to these climatic conditions.”

Duroux acknowledged that climate change has brought some benefits to Bordeaux in recent years, including riper grapes and richer wines during particularly hot vintages such as 2020, 2022 and 2025.
But he warned that without significant rainfall in the coming weeks, vines could shut down to conserve water, causing grapes to shrivel and reducing both yields and quality.
The smoke taint debate
Attention is also turning to the risk of “smoke taint”, a controversial issue in the wine world.
Smoke taint occurs when compounds released by wildfire smoke are absorbed into grape skins. During red wine fermentation, these compounds can be extracted from the skins, potentially giving wines undesirable smoky, ashy or medicinal flavours. The extent of the risk depends on factors including the vineyard’s proximity to the fire, the density and duration of smoke exposure, and the stage of grape development.
Posting on LinkedIn, wine brand creator and consultant Robert Joseph warned that vineyards within 50 to 100 kilometres downwind of major fires should be monitored closely.
“For Bordeaux in late July, with véraison beginning, vineyards lying anywhere within 50–100 km downwind of a substantial fire are worth monitoring or testing,” he wrote.
“A 20 km or even 50 km separation should not automatically reassure growers if fresh smoke has remained over the vines for several hours,” he added. Red Bordeaux varieties may also reveal the problem more strongly because red-wine fermentation extracts smoke-derived compounds from the skins.”
Winemaker Sally Evans echoed those concerns. “We have woken up to smoke again this morning after a couple of days’ respite. The difficulty is the fact that this can reveal itself so far down the line – post fermentation and even after some time in bottle.
“The possible risk may encourage even more of us to make some Blanc de Noir this year given it is the skin contact which is the most problematic… already in the plan for this year but maybe we should make more than had planned.”
However, Colin Hay, the drinks business‘ Bordeaux correspondent, urged caution against drawing premature conclusions.
“There’s very little established scientific evidence to date of smoke taint being passed to vines that are not in close proximity to the fire itself — and at present the nearest vineyards are at around 15km from the source of the smoke to which they are exposed,” he told db. “Some vineyards are geographically closer, but the smoke they have experienced has come from further away due to the prevailing wind direction.”
Hay said Bordeaux’s experience during the 2022 wildfires offered some reassurance.
“There were certainly anxieties then and much talk of smoke taint. But in the end any suggestion of smoke taint in the wines vinified was restricted to some isolated parcels in the Graves that were never used in the final blend and that came from parcels directly adjacent to the fire itself.”
He added that the unusual conditions of the 2026 growing season could also reduce the immediate risk.
“Many vines, suffering as they are from a combination of thermal and hydric stress, are in a current stage of blockage, with the bunches essentially stuck at 10-20% of véraison. Physiologically not much is happening and that is likely to reduce any absorption of smoke for now at least.”
