The Santa Ynez Valley AVA includes which of the following sub AVAs?

The Santa Ynez Valley AVA (American Viticultural Area) is a prominent wine-producing region in California's Santa Barbara County and is known for its diverse climate and terroir. Among its sub-AVAs, the Santa Rita Hills is particularly notable. Located within the Santa Ynez Valley, the Santa Rita Hills sub-AVA is recognized for its cooler climate, which is ideal for growing Pinot Noir and Chardonnay grapes. The unique topography and climatic conditions contribute to the distinct character of the wines produced in this area.

Santa Lucia Highlands, San Antonio Valley, and Santana Valley do not fall under the Santa Ynez Valley AVA. The Santa Lucia Highlands is situated further north, near Monterey County, while San Antonio Valley is also outside of the Santa Ynez Valley region. Santana Valley is not recognized as an official sub-AVA related to Santa Ynez Valley either. Therefore, the choice of Santa Rita Hills is correct as it is a recognized sub-AVA within the larger Santa Ynez Valley AVA.
