Why Is Korbel Called "Champagne" If It's From California?

Korbel's use of "Champagne" on its label, despite being produced entirely in California, is a genuine legal exception rather than an error or loophole being quietly ignored.

The 2006 US-EU Agreement

In 2006, the United States and European Union signed a wine trade agreement that restricted the use of certain protected European wine terms (including "Champagne") for new American wine labels going forward — but it included a grandfather clause allowing producers who were already using those terms before the agreement to continue doing so.

Korbel's Long History With the Term

Korbel had been using "Champagne" on its label for many decades before the 2006 agreement, qualifying it for the grandfathered exception — meaning Korbel can legally continue calling its product "California Champagne" domestically within the US, even though new American producers cannot adopt the term going forward.

Why This Only Applies Domestically

The grandfather clause applies specifically to the US domestic market — Korbel cannot export products labeled "Champagne" to the European Union or other regions that enforce the protected designation, meaning the same product may need different labeling depending on where it's sold internationally.

Other Grandfathered American Producers

Korbel isn't the only beneficiary of this exception — several other long-established American sparkling wine producers with a similarly long history of using "Champagne" on their labels retain the same grandfathered right, though the list of qualifying producers is fixed and doesn't grow over time.

Why This Matters for Wine Labeling Broadly

This situation is a genuinely interesting case study in how international trade law interacts with existing commercial practice — rather than forcing an abrupt, retroactive change that would have disrupted established brands, the agreement carved out a specific, limited exception for existing use while closing the door to new adoption.

The Bottom Line

Korbel's "California Champagne" labeling is a real, legally sanctioned exception dating to established pre-2006 use, not a violation of Champagne's protected status — a genuinely unusual quirk in international wine-labeling law worth knowing next time you see the term on a California bottle.
