Climate and geography
Located within the large multi-county South Coast AVA, Ramona Valley was the third AVA to be designated in Southern California, after San Pasqual Valley AVA in 1981 and Temecula Valley AVA in 1984. In an interview on National Public Radio, Bill Schweitzer of the Ramona Valley Vineyard Association described the area's exceptional viticultural characteristics as being partially derived from its unique location of being 25 miles (40 km) east of the Pacific Ocean and 25 miles (40 km) west of the Colorado Desert.
Currently the Ramona Valley AVA is home to more than 80 commercial vineyards with over 100 acres (40 ha) of varieties of both white and red grapes in cultivation. As of 2016, there were over 20 bonded wineries operating in the AVA.
