Temecula Valley AVA
Temecula Valley is an American Viticultural Area (AVA) within the Temecula Valley landform, located in southwestern Riverside County, California nestled along the eastern slopes of the Santa Ana Mountains. It was established as the nation's 69th, the state's 42nd and the county's initial appellation on October 23, 1984 by the Bureau of Alcohol, Tobacco and Firearms (ATF), Treasury after reviewing petitions submitted by the Rancho California/Temecula Winegrowers Association and Callaway Vineyard and Winery, Temecula, California in 1981 proposing a viticultural area in Riverside County named "Temecula." In 1982, the petitioners initially proposed multiple viticultural areas named "Temecula," "Murrieta," and "Rancho California" but the ATF did not adopt them.
