Why California Can Legally Call It "Champagne" (Blame the US Senate)

The Treaty of Versailles protected the Champagne name worldwide. Then the US Senate refused to ratify it. A century later, "California Champagne" is still technically legal — and the French are still furious.

The Treaty

June 28, 1919. The Hall of Mirrors at the Palace of Versailles. The same room where the German Empire had been proclaimed in 1871 — after humiliating France in the Franco-Prussian War — was now the setting for Germany’s forced surrender. The French had insisted on the location. Revenge is a dish best served in the same room.

The Treaty of Versailles was, by any measure, one of the most consequential documents in modern history. It redrew the map of Europe, created the League of Nations, imposed crippling reparations on Germany, and — in Paragraph 275 — established international protection for geographic product names, including Champagne.

Article 275 was clear: the name “Champagne” could only be used for sparkling wine produced in the Champagne region of France, according to specific methods and regulations. Every nation that signed the treaty agreed to enforce this protection.

Twenty-seven delegations representing 32 powers signed the treaty. The United States was not one of them.


The Vote

Why did the US Senate reject the Treaty of Versailles?

The US had helped negotiate the treaty. President Woodrow Wilson had traveled to Paris for the peace conference, pushed for the League of Nations, and considered the treaty his defining achievement. But ratification required a two-thirds majority in the Senate, and Wilson couldn’t get it.

The fight was primarily over Article 10 of the League of Nations covenant, which opponents argued could commit American troops to foreign conflicts without Congressional approval. Senator Henry Cabot Lodge led the opposition. The debate was bitter, personal, and consumed Washington for months.

On November 19, 1919, the Senate voted. The treaty failed: 49 against, 35 in favor — well short of the two-thirds needed. A second vote on March 19, 1920, also failed: 49-35 again, the exact same margin. The US never ratified the Treaty of Versailles.

Wilson, who had suffered a devastating stroke in October 1919, was too incapacitated to negotiate a compromise. The treaty that he had championed as the foundation of a new world order died in the institution he could not persuade.


The Loophole

How did the Treaty of Versailles create the California Champagne loophole?

Here’s where it gets interesting for wine.

Because the US never ratified the Treaty of Versailles, the protections in Paragraph 275 were never legally binding in America. The Champagne appellation — fiercely protected in every signatory nation — had no legal standing in the United States.

American producers noticed.

Through the 20th century, several American wineries — particularly in California — began labeling their sparkling wines as “Champagne.” The labels typically read “California Champagne” or “American Champagne,” but the C-word was there, in full. The French protested. American producers pointed to the law — or rather, the absence of law. No treaty, no protection. Simple.

The situation was partially addressed in 2006, when a bilateral wine trade agreement between the US and the EU restricted the use of “Champagne” on new American wine labels. But — and this is the critical detail — producers who were already using the term before 2006 were grandfathered in. They could continue labeling their sparkling wine as “Champagne” indefinitely.


The Survivors

Which American brands can still legally use the Champagne label?

As of 2026, a handful of American producers still sell sparkling wine labeled “Champagne.” The most prominent include Korbel (which supplies Times Square’s official New Year’s Eve champagne), Cook’s, and André. These brands were using the term before the 2006 agreement and are legally permitted to continue.

The French champagne industry — represented by the Comité Interprofessionnel du Vin de Champagne (CIVC) — has lobbied against this for decades. They argue that “Champagne” is a geographic indicator, not a generic term, and that using it for wine produced anywhere outside the Champagne region constitutes fraud. In the EU, they’re right. In the US, the law disagrees.

The irony is sharp. The Treaty of Versailles was about much more than wine — it was about territorial borders, military restrictions, and war reparations. But the Senate’s refusal to ratify it, driven by fears about the League of Nations and American sovereignty, had the unintended consequence of leaving one of France’s most valuable luxury brands unprotected in one of the world’s largest consumer markets.


The French Position

The French view is straightforward and deeply held: Champagne is a place, not a product. The word describes wine made from specific grapes (Chardonnay, Pinot Noir, Pinot Meunier), grown in specific soil (chalk), in a specific climate (the northernmost major wine region in France), using a specific method (méthode champenoise). No wine produced in California — regardless of its quality — is Champagne, because California is not Champagne.

This position is enshrined in EU law, enforced by French courts, and recognized by nearly every wine-producing country on earth except the United States (and even there, only for pre-2006 labels). The CIVC has sued producers, lobbied governments, and maintained a decades-long public campaign to protect the name.

From the French perspective, calling California sparkling wine “Champagne” is like calling Wisconsin cheese “Parmigiano-Reggiano.” The comparison is not perfect — geographic wine appellations are more legally established than cheese designations — but the principle is identical: the name tells you where it’s from, and using it for a product from somewhere else is deceptive.


The American Position

The American position is less about wine philosophy and more about legal pragmatism. The labels are grandfathered. The producers have been using them for decades. Changing them would cost money, confuse consumers, and solve a problem that most American wine drinkers don’t care about.

Most American consumers, when pressed, understand that “California Champagne” is not from France. They buy it because it’s affordable, familiar, and festive — not because they’re confused about geography. The producers argue that “champagne” has become a generic term in American English, like “aspirin” or “escalator,” and that protecting it as a geographic indicator is a European concern, not an American one.

This argument enrages the French. But as long as the labels are legal, the argument continues. It’s one of nine champagne myths that even wine lovers believe — the idea that “champagne” is just a generic word, rather than a place.


The Bigger Picture

The California Champagne loophole is, in the end, a footnote to a much larger story. The Senate’s refusal to ratify the Treaty of Versailles had consequences far beyond wine labels: the US never joined the League of Nations, which weakened the institution and contributed to its failure to prevent World War II.

But the wine angle persists as one of history’s most unexpected consequences. A treaty negotiated in the Hall of Mirrors by world leaders redrawing the map of Europe after the deadliest conflict in human history… resulted, among other things, in Korbel being allowed to put “Champagne” on its labels in perpetuity.

History is rarely tidy. Sometimes a vote about the League of Nations decides what you can call a bottle of sparkling wine 107 years later. The treaty was just one chapter in 5,000 years of champagne history — a story that stretches from Sumerian beer goddesses to Baltic shipwrecks.


FAQ

Why can California call sparkling wine champagne?

Because the US Senate refused to ratify the Treaty of Versailles in 1919 — twice, by the exact same 49-35 margin. Article 275 of the treaty protected the Champagne name internationally, but since the US never signed, those protections had no legal standing in America. A 2006 US-EU wine trade agreement finally restricted new labels, but producers already using the term were grandfathered in and can continue indefinitely.

Is California Champagne really champagne?

No. Real Champagne comes exclusively from the Champagne region of northeastern France, made from specific grapes (Chardonnay, Pinot Noir, Pinot Meunier) grown in chalk soil using the methode champenoise. “California Champagne” is sparkling wine produced in California. It is legally permitted to use the name in the US only because of the Treaty of Versailles loophole, but nearly every wine-producing country on earth recognizes that Champagne is a geographic indicator, not a generic term.

Which American brands still use the champagne label?

As of 2026, the most prominent brands still labeling their sparkling wine as “Champagne” include Korbel (which supplies Times Square’s official New Year’s Eve champagne), Cook’s, and Andre. These producers were all using the term before the 2006 US-EU agreement and are legally grandfathered in. No new American producer can start using the Champagne label — only those with pre-2006 labels are permitted to continue.

When was the champagne name protected internationally?

The Treaty of Versailles, signed on June 28, 1919, established international protection for the Champagne name in Article 275. All 32 signatory powers agreed to enforce this protection. However, the real teeth came later: EU law now fiercely protects the appellation, and the CIVC (Comite Interprofessionnel du Vin de Champagne) has successfully enforced the name in nearly every country. The US remains the major exception, and only for grandfathered pre-2006 labels.


The Treaty of Versailles was signed in the Hall of Mirrors at the Palace of Versailles — the same room featured in our history of champagne and world power. The full 5,000-year story from Sumerian beer to Baltic shipwrecks is in The Complete History of Champagne.
