Sta. Rita Hills received its designation as an AVA in 2001, under the name Santa Rita Hills. In 2005, after a name dispute with the Chilean producer Vina Santa Rita, the region changed its name to Sta. Rita Hills. The region is situated on 30,720 acres in Santa Barbara County. Soil types within the Sta. Rita Hills are notoriously varied between mixed loams, Diatomaceous Earth, and shale. The valley's proximity to the Pacific Ocean along with its east to west running hills allow fog and wind off the Pacific to settle over the grapes and creates a cool growing climate. The cool climate has made the Sta. Rita Hills an excellent area for growing Chardonnay and Pinot Noir.
