Why some of France’s most famous cheeses are in peril

France’s Iconic Cheeses Face an Existential Threat as Record Heat and Drought Reshape the Pasture

Activelifezero.com – The rolling hills of southeastern France, long defined by the emerald sweep of summer meadows, have turned a brittle, sun-bleached gold. For the farmers who depend on those pastures to produce some of the world’s most celebrated artisanal cheeses, the transformation is not merely cosmetic. It is an economic and cultural emergency. Scientists and cheesemakers alike now warn that climate-driven heat extremes and prolonged drought are eroding the very foundation of France’s terroir cheese tradition — the intimate link between a specific landscape, its microbial ecology, and the flavor that emerges from milk produced within it.

A Farmer’s Thirty-Five-Year Warning

Laurent Lours has spent three and a half decades both raising dairy cattle and crafting cheese in the Cantal department. His observation of how frequently the pastures fail has shifted dramatically within his working lifetime.

“Before, we used to have a problem with the grass every 15-20 years. Now, it’s about every other year. And it’s getting worse.”

The consequences cascade quickly. Cows under thermal stress produce less milk. Calves arrive smaller, weaker, or not at all. Producers of premium-tier cheeses have been compelled to halt operations entirely. The sensory signature that distinguishes a terroir product from a generic factory cheese — built over centuries of specific grasses, specific soils, specific altitude — is now at risk of dilution or disappearance.

“We’ve had five heat waves so far this year. We’ve never experienced temperatures like this before,” Lours says.

July 2026: A Statistical Anomaly

France’s national meteorological service confirmed that July this year became the hottest month recorded since systematic observation began in 1900. Simultaneously, it ranked as the third driest July on record. The convergence of extreme heat and moisture deficit created conditions that scorched pastures across multiple departments within weeks, stripping them of the lush, protein-rich forage that dairy cattle require during their summer grazing season.

Salers: The Cheese Most Exposed

Among the 47 French cheeses bearing the AOP designation — Appellation d’origine protégée, or “protected designation of origin” — Salers stands out as particularly vulnerable. A semi-hard, raw cow’s-milk cheese, Salers is produced almost exclusively in the Cantal department within the Auvergne-Rhône-Alpes region. Its cows graze at elevations between roughly 800 and 1,500 meters (2,630 to 4,920 feet) atop a volcanic massif whose mineral-rich soils support a dense carpet of wild grasses.

No two wheels of Salers are identical, yet the local terroir — the particular blend of microclimate, geology, and topography — yields a recognizable flavor arc: notes of walnut and hazelnut, fresh-cut grass, fermented cream, a whisper of peppery spice, and the char of smoked or grilled onion. That profile is inseparable from the pasture itself.

This summer, more than three-quarters of France’s 80 registered Salers producers were forced to a complete standstill after successive heat events and the accompanying drought rendered pastures unusable.

The Regulatory Cage

Salers production is governed by a narrow calendar: cheese may be made only between April 15 and November 15, and the cows must be predominantly grass-fed. Dietary supplementation is capped at 25 percent of total dry matter intake, and permitted supplemental ingredients — hay, wheat, barley, oats, maize — must originate from within the designated AOP zone. These constraints, designed to protect authenticity, become a liability when the pasture simply does not exist.

Faced with that reality, Lours ceased Salers production on July 8 and pivoted to Cantal, a semi-hard cow’s-milk cheese with a comparable but less rigid regulatory envelope. Cantal may be produced year-round, and its rules require only that cows graze at least 120 days annually, with a more permissive ratio of grass to grain, hay, and corn.

Emergency Measures from the INAO

Last month, the Institut national de l’origine et de la qualité (INAO), the governmental body that administers the AOP label, announced temporary modifications for a select group of cheesemakers in response to what it termed France’s “historic drought.” Producers of Beaufort, Comté, and Abondance were among the first authorized to raise the proportion of supplemental fodder in their cows’ diets or to source feed from outside their designated geographic zones. The list of cheeses receiving such waivers is expected to expand.

The Question of Permanence

Lours, who also serves as president of the Comité interprofessionnel des fromages du Cantal and speaks for local cheesemakers, explained that his group deliberately declined to petition for a temporary exemption on Salers. In his judgment, any product in which less than half the dry-matter intake comes from pasture-grown grass would not “deserve the designation” of the Salers name.

For years, producers of several AOP cheeses have lobbied the INAO to permanently recalibrate regulations in light of anthropogenic climate change — adjusting grazing windows, raising allowable supplemental-feed thresholds, and permitting feed procurement beyond the AOP boundary. The administrative process is protracted, often spanning multiple years before finalization.

The unresolved question hanging over France’s cheese landscape is whether relaxing those minimums preserves the product’s identity or quietly hollows it out. If the pastures continue to fail with increasing frequency, the answer may be forced upon producers whether or not the flavor survives the transition intact.
