Coastal Breezes Meet Inland Warmth
The Central Coast Region includes the Zinfandel growing areas of Monterey County, San Luis Obispo County (including Paso Robles), Edna Valley, and Santa Barbara. Each of these areas contains vineyards that share the effects of coastal breezes, which moderate the warmth of the summer and early fall. Within the region, each AVA experiences micro-climates from a “thermal rainbow™” in Monterey spreading north-to-south, to coastal fog, and inland valley heat.
Most of the soil here is rocky and gravelly, with loam throughout. Paso Robles has predominantly calcareous soils and the high soil pH values of 7.4 to 8.6; with a longer growing season, this helps to develop fully mature fruit whose acid chemistry maintains balance during the cool nights. A little south, the soils are lean and shallow, quickly yielding to hard bedrock which brings beneficial stress to the region’s grapevines.
Zinfandel was first planted in the Central Coast by the mid-1880’s, and the region has a long history of winemaking dating back to the advent of the missionaries in the 18th century.
