Cole Ranch is an American Viticultural Area (AVA) located in Mendocino County, California.
The small viticultural area was established on April 15, 1983 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing the petition submitted by the proprietor of Cole Ranch in Ukiah, California.
The viticultural area is located in a small, narrow mountain valley west of Hwy 101 on the 500 acres (0.78 sq mi) ranch originally owned by the Cole family.
Several prominent wineries source grapes from Cole Ranch including Fetzer Vineyards and Chateau St. Jean.
[4][3] As of 2024, the Sterling family, proprietors of the Esterlina Winery located at Philo, owns the vineyard acreage.
