Robert Mondavi Winery Secures Victory in To Kalon Name Dispute

Following a lengthy five-year battle, the U.S. Board of Geographic Names has revoked the designation of To Kalon Creek, granting a significant victory to Constellation Brands, the parent company of Robert Mondavi Winery. This decision was finalized on August 14, 2025, after the agency reversed its 2017 recognition of the creek’s name, favoring Constellation’s petition to have it removed from the official list of geographic names. The creek, now known as Doak Creek, flows through the To Kalon Vineyard, from which Constellation holds a trademark on the name "To Kalon."

Constellation Brands expressed satisfaction with the ruling, stating it upholds the integrity of their trademark. However, the decision has sparked concerns among Napa vintners who believe that To Kalon Vineyard remains one of America’s exceptional wine regions deserving recognition as a distinct terroir, rather than as merely a brand owned by a corporation. Vintner Graeme MacDonald, advocating for the vineyard’s heritage, emphasized the importance of preserving the authenticity of historic wine sites.

Initially, Constellation had supported MacDonald in his efforts to have the creek named after To Kalon. However, the company later argued that the name posed a risk to its trademark. MacDonald countered this claim with historical evidence, showcasing documentation that confirmed the creek’s name dating back to the late 1800s.

To Kalon’s history dates back to the 1800s, when Hamilton Walker Crabb purchased land in Oakville and named his vineyard and winery To Kalon in 1886. Ownership has changed hands since then, but Constellation now controls the majority of the vineyard. Other claimants, like Beckstoffer and several others, continue to grow grapes from their sections of the vineyard, highlighting ongoing disputes about the area’s heritage.

Beckstoffer lamented the decision, calling it a significant reversal that disregards solid historical research. He, alongside others, fears that this ruling sets a concerning precedent regarding naming rights in American wine. They believe that To Kalon is more than just a name; it is a historical site crucial to the identity of Napa Valley’s winemaking legacy.

As the wine community reflects on the implications of this decision, there are concerns about the potential loss of the To Kalon legacy and the impact of corporate interests on the authenticity of significant heritage in American viticulture.
