What winery did Christophe Baron start in Walla Walla?

Christophe Baron is the founder of Cayuse Vineyards, which is well-known for its unique and exceptional wines produced in the Walla Walla Valley. The vineyard is celebrated for its commitment to using organic and biodynamic farming practices, which contribute to the distinct terroir of the region. Cayuse Vineyards has gained significant acclaim and recognition in the wine community, particularly for its syrah and other varietals.

The other choices represent different entities but are not associated with Christophe Baron. Baron Estates, for example, is a separate winery founded by a different individual and does not carry the same recognition that Cayuse does for its high-quality production and innovative approaches. Walla Walla Valley Wines is a broader term that encompasses various wineries in the area rather than a specific winery. Lone Birch Winery, similarly, is another establishment altogether, distinct from Baron's notable contributions to the Walla Walla region. Thus, Cayuse Vineyards accurately identifies the winery linked to Christophe Baron.
