Centrally located between San Francisco and Los Angeles along California's Central Coast, Paso Robles Wine Country is California's fastest growing wine region and largest geographic appellation. With a greater day-to-night temperature swing than any other appellation in California, distinct micro-climates, diverse soils and a long growing season, Paso Robles is a unique wine region blessed with optimal growing conditions for producing premium and ultra premium wines.
Its western boundary is just six miles from the Pacific Ocean. The appellation lies on the inland side of the Santa Lucia coastal mountains in San Luis Obispo County, and roughly forms a rectangle 35 miles from east to west, and 25 miles from north to south. It extends from the Monterey County border to the north, to the Cuesta Grade below Santa Margarita to the south, and from the Santa Lucia Mountains to the west, to the Cholame Hills to the east.
The appellation comprises 614,000 acres of which more than 26,000 acres are in wine grape vines. It is the fastest growing and largest by far of three AVAs in San Luis Obispo County, and the main reason that the county ranks behind only Napa, Sonoma and Monterey counties in planted acreage among the state's coastal growing areas.Soils
California's Central Coast is geologically different from other California wine growing regions. Unlike others with deep, rich fertile valley soils, there are four general soil types in the Paso Robles AVA primarily formed from weathering granite, serpentine, shale and limestone, with shale and limestone being the most predominant bedrock types. Soil diversity is the norm and a vineyard block may commonly contain several different soil types. One distinguishing factor of the Paso Robles AVA is the abundance of highly desirable limestone and calcareous-rich soils found throughout the region.
Due to cool nights and warm days, and typically late rains, Paso Robles vines tend to have a longer growing season and grapes have more hang time compared to other wine regions, resulting in fully mature fruit whose acid chemistry is kept in balance through the area's overnight cooling.
