France's wine production nears a 70-year low, leaving winemakers with tough choices

Primary Journalistic Dispatch & Direct Reporting

Florent Latour, CEO of the largest owner of Grand Cru vineyards in Burgundy, spent the summer praying for rain.

"We felt we were so close," Latour, who's head of Maison Louis Latour, told CNBC. "Just a bit more rain would have produced a fantastic harvest on both counts, but we had to settle for quality, and about half of a harvest."

His prayers - and frustrations - are being echoed across France, as a record-hot summer and severe droughts hit the country's world-famous wine industry hard.

In-Depth Developments & Factual Context

France's agriculture ministry has warned that wine production could hit a 70-year low in 2026, marking the third year of reduced output.

"The 2023 vintage was decent, but yields have been pretty disastrous since the start of the decade," said Jean-Marie Cardebat, chair of wines and spirits at the INSEEC Grande École university. "We are realizing that no region in France is safe from heatwaves today."

Paradoxically, the regions that suffer the most are those with more temperate climates, namely the Loire Valley and Champagne. In contrast, winemakers in the southern regions of Bordeaux and Languedoc-Roussillon reported higher harvests compared to last year.

Industry Impact & Strategic Analysis

For Cardebat, also an economics professor at the University of Bordeaux, France's poor preparation in the face of climate change is a big problem.

"Spain is more often affected by heatwaves and global warming; however, it is better prepared," he said. "Partly because it already has an irrigation network in place."

This is rare in France, he said, and permitted only in exceptional cases. "In France, setting up such measures takes time."

Forward Outlook & Market Perspective

The impacts of climate change are heightening the debate around the strict rules that govern France's wine sector.

Last year, Chateau Lafleur caused a storm by withdrawing from the prestigious Pomerol and wider Bordeaux official designations for their six wines.

Owned by the Guinaudeau family, the estate said that rigid appellation (AOC) rules - which include irrigation restrictions, planting densities, and permitted grape varieties among others - prevented it from adapting quickly enough to the changing climate.

Moving away from these rules will allow the vineyard to deal with "the reality of climate change with precision and effectiveness," the Guinaudeau family explained at the time. "It is a bold decision that enables the entire Lafleur Family … to ensure the perennity of our vineyards and the quality and identity of our wines. In a word: the future."

High temperatures also mean earlier harvests, which can cause major logistical problems for winemakers.

"This year we started on the 14th of August, which is the earliest ever for the Latour domaine ... What we've seen, if you take it per decade, is that the midpoint of the harvest is three days earlier every decade, so essentially we've moved a month since the 1930s," Latour said.
