In what year was California's Santa Clara Valley recognized as an AVA (American Viticultural Area)?

C. 1989

The Santa Clara Valley AVA extends south of the San Francisco Bay, along the Santa Cruz Mountains, in California's Central Coast area, and has winemaking and viticultural history dating back to the Spanish missionaries of the area in 1798. During the gold rush of the 1850s, European immigrants from France, Italy, Germany, and Spain recognized the potential of the area for grape-growing, and planting well-known varieties from their countries. It was recognized as an AVA in 1989. Today, the Santa Clara Valley AVA is home to about 30 wineries.
