Pacheco Pass is an American Viticultural Area (AVA) located in the Santa Clara and San Benito counties of California. It lies within the larger San Francisco Bay viticultural area. Pacheco Pass was established on April 11, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after evaluating the petition submitted by Mr. H.G. Zanger of Pacheco Pass Vineyard, later renamed "Zanger Vineyards", proposing an area near Hollister, California, as a viticultural area known as "Pacheco Pass."
