What’s in a Name? Federal Board Weighs the Meaning of “To Kalon

The U.S. Board of Geographic Names (BGN) is set to address the controversy surrounding the To Kalon Vineyard in Napa Valley, specifically regarding the creek that flows through it. This debate centers on whether To Kalon is recognized as a specific geographical location or merely a trademarked brand.

After five years of legal challenges, the BGN will convene on July 10, 2025, in Washington, D.C., to discuss a possible reversal of its 2017 decision recognizing To Kalon Creek. Initially supported by Constellation Brands, which owns Robert Mondavi Winery, this vineyard has earned acclaim for its grapes, integral to prestigious producers like Opus One and Andy Beckstoffer. However, Constellation now contends that To Kalon is a brand and not a geographic place, arguing that the name’s recognition undermines their trademark rights.

According to Constellation, "To Kalon as a defined geographic place doesn’t exist, and never has." If deemed a brand, this would limit the use of the name to the trademark owner, allowing them to label wines "To Kalon" irrespective of their sourcing.

The historical significance of To Kalon is profound. Originally established in the mid-1800s by Hamilton Walker Crabb, the vineyard has changed hands multiple times and is now largely owned by Constellation Brands. Seven other entities, including Opus One and University of California, Davis, also lay claim to portions of the land linked to its historical boundaries.

Graeme MacDonald, who farms a 15-acre parcel of MacDonald Vineyards located next to the Mondavi property, has gathered a wealth of historical documentation and previously succeeded in getting the creek named. He argues that the historical connection to the To Kalon name must be preserved. MacDonald is prepared to present his case during the board meeting, emphasizing the creek’s long-standing recognition in Napa Valley.

The BGN will hear from both parties and is expected to make its decision by August. The outcome of this debate could set crucial precedents regarding the designation of vineyard names and their geographical significance in the American wine industry.
