The small York Mountain AVA is in the western part of San Luis Obispo County. The region is near the Templeton Gap, which is a funnel for coastal winds, making the temperature quite a bit cooler than areas to the east. Local rainfall is also higher and the mountain soils shallower, producing unique, distinctive wines.

York Mountain has three wineries and only a couple hundred acres of vineyards. Unlike most producers in Paso Robles to the east, York Mountain wineries produce wines that are known more for grace than for power. The grapes are grown in a moderate and elevated climate that is only about seven miles inland from of the Pacific Ocean. The region is blessed with the combination of a long and sunny growing season that is moderated by maritime breezes and cool overnight temperatures.

Andrew York established the region’s first commercial winery. Originally called Ascension Winery, it has since been renamed York Mountain Winery, but was in the same family's hands until 1970! (Wine/Appellations)
