How Climate Change Put French Mustard on the Brink
A deep dive into how global warming and supply chain shocks have threatened France’s iconic condiment.
France‘s love for mustard is woven into the fabric of its culinary identity. Dijon mustard, hailing from the Burgundy region, is an essential companion in French kitchens, cafeterias, and restaurants. But in recent years, the ubiquitous jars of this spicy, tangy condiment have quietly disappeared from supermarket shelves. The culprit: an unprecedented confluence of climate extremes, global supply chain fragility, and geopolitical shocks.
France’s Iconic Mustard: A Heritage Under Threat
French mustard, especially Dijon mustard, is world-renowned—the product of centuries of tradition and meticulous craftsmanship. Typically, Burgundy’s local wine forms a key ingredient, and the seeds, mostly brown mustard seeds, are blended according to time-honored recipes. Once a constant through wars, revolutions, and crises, French mustard seemed untouchable. Yet today, it is a bellwether for a world where even everyday foods are at the mercy of climate change and global supply chain disruptions.
Mustard in French Life
- Essential for classic dishes: vinaigrettes, charcuterie, steak sauces, and sandwiches.
- Dijon mustard is a global export and staple in homes across France.
- Long history intertwined with Burgundy’s cultural and agricultural heritage.
Why Mustard Vanished from French Shelves
Starting in 2021, French consumers noticed a growing scarcity of their favorite mustard varieties. Stores received fewer shipments; certain brands vanished entirely. The crisis had begun with a series of environmental and economic shocks that rippled through the interconnected global network of food suppliers.
The 2021 Harvest Crisis
- Canada: The world’s largest exporter of mustard seed suffered a historic heatwave and drought, reducing yields by 28%. The “heat dome” event in early July decimated crops across the prairies, and Canadian supply—a vital pillar for French producers—collapsed.
- Burgundy, France: While Canada scorched, France contended with the opposite: an abnormally wet winter followed by a cold snap in April. The mustard harvest fell to just 50% of normal yields. Producers described losses unseen in decades.
The Numbers Behind the Mustard Shortage
| Region | 2021 Yield Change | Key Factors |
|---|---|---|
| Canada | -28% | Heatwaves, drought |
| Burgundy, France | -50% | Wet winter, cold snap |
Escalating Prices and Scarcity
- Price of mustard seeds soared—French producers reported prices rising three- to six-fold within a single year.
- Reine de Dijon, one of France’s largest producers, paid six times the previous year’s price on the open market.
- Retail prices for mustard in France increased by at least 10% within months, driven by costs for seeds, transportation, packaging, and glass jars.
- Consumers faced empty shelves and rationing, with some retailers limiting purchase quantities.
Global Supply Chain Fragility Exposed
The mustard crisis highlights a deep vulnerability in our food systems: global supply chains have stretched for efficiency, but at the cost of resilience. When a single climate event or supply shock hits a major producing region, it sends shockwaves across the world.
Why the World Ran Out of Mustard
Two-thirds of the mustard seed used in French mustard comes from Canada. When Canadian crops failed, French producers expected to turn to backup suppliers. Yet the backup plan quickly unraveled when the war in Ukraine broke out in February 2022. Ukraine and Russia are also major mustard seed exporters, but imports became nearly impossible as conflict froze supply lines and restricted agricultural output.
What others are reading
- Canadian crop failure cut off the main supply.
- War in Ukraine wiped out the fallback option for seeds.
- Rising energy and packaging costs added extra strain for producers and retailers.
How Vulnerable is the Supply Chain?
According to analysis, global food and manufacturing supply chains have become increasingly “just-in-time”—optimized for cost, not for shocks. As Tim Benton of Chatham House notes, “If anything goes wrong everything stops, and the number of ways disruption can happen is enormous: extreme weather, pest outbreaks, energy interruptions, wars, or sudden shifts in demand.”
Mustard is Not Alone: A Symptom of a Larger Crisis
French mustard is only one of several iconic foods and condiments facing existential threats in the warming world. Extreme climate events have imperiled harvests and supply lines for other staples:
- Sriracha Hot Sauce: Production halted in 2022 due to a chili pepper shortage caused by drought in Mexico.
- Ketchup: COVID-19 and supply chain bottlenecks caused a shortage of packets and single-serve containers as restaurants shifted to takeout.
- Tomato Sauce: Droughts in California threaten global pizza and pasta supplies.
- Dairy and Cheese: Repeated heatwaves threaten European and American milk production, impacting cheese and butter output.
Producers Search for Solutions
French mustard makers, chief among them Reine de Dijon, have tried to adapt by sourcing seeds wherever possible—sometimes even eyeing suppliers from non-traditional regions such as England. In 2021, the UK had a rare bumper crop, turning it into a hot prospect for European producers desperate to keep factories running.
- Higher prices and short-term contracts for British-grown mustard seed.
- Efforts to persuade more French farmers to plant brown mustard, often met with reluctance due to weather unpredictability and risk.
- Investment in new seed varieties with greater climate resilience.
Will Mustard’s Future Be Sustainable?
Producers warn that repeated crop failures could mean permanently higher prices—and that traditional Dijon mustard may never be as accessible or affordable as in decades past. Despite technological solutions, recovery is slow. Some companies are also experimenting with blends using alternative seeds, but the distinct flavor profile is at risk of changing.
The Bigger Picture: Lessons for Our Food System
- Long Supply Chains = Higher Risk: Reliance on long, international supply chains magnifies the impact of climate or conflict disruptions.
- Efficiency at the Expense of Resilience: Highly optimized “just-in-time” systems succeed in stable times but falter dramatically under stress.
- Climate Adaptation is Urgent: Investments in crop diversification, sustainable water use, and climate-resilient agriculture are critical for long-term food security.
- Vulnerability of Signature Foods: Condiments, cheeses, and regional food specialties are cultural treasures, but increasingly fragile in a warming, conflict-prone world.
Frequently Asked Questions (FAQs)
Q: Why does France rely so heavily on Canadian mustard seeds?
A: Canadian prairies provide the climate and scale needed for brown mustard seed production. French farmers grow some mustard, but domestic yields cannot meet industry demand, especially during years of poor weather.
Q: How has climate change affected mustard farming in France and Canada?
A: In Canada, record-breaking heat and drought have devastated harvests. In France, opposing hazards—wet winters and unseasonable cold snaps—have similarly reduced output by half or more.
Q: Has the war in Ukraine really made the mustard shortage worse?
A: Yes. Ukraine and Russia were important alternative suppliers of mustard seed to France and other European countries. The outbreak of war made imports nearly impossible, leaving producers with no fallback supply.
Q: Is the mustard shortage a temporary or permanent problem?
A: While supply may recover if harvests and geopolitics stabilize, the underlying drivers—climate volatility and supply chain fragility—mean disruptions are likely to continue, raising the risk of ongoing shortages and higher prices.
Q: Are there other foods at similar risk?
A: Yes. Many globally-traded foods face risks from climate change and shock-sensitive supply chains, including tomatoes, peppers, dairy, grains, and even seafood.
Key Takeaways
- Climate change and supply chain shocks have turned Dijon mustard—an institution in French cuisine—into a scarce and expensive commodity.
- Extreme weather in Canada and France, compounded by war in Ukraine, wiped out critical seed supplies and sent global prices soaring.
- Global food systems, optimized for efficiency, are increasingly fragile in the face of environmental and geopolitical crisis.
- Wider lessons for food security demand urgent adaptation: shorter supply chains, diversified crop sources, and climate-resilient agriculture are now essential.
