About the Paso Robles AVA

Paso Robles, designated 1983, covers a large stretch of inland San Luis Obispo County between the coastal range and the Central Valley. The climate is hot Mediterranean by day with substantial cooling at night — diurnal swings of 40–50°F are routine, and the AVA's reputation for producing structured wines despite the heat is generally credited to that overnight recovery.

In 2014 the TTB approved eleven sub-AVAs inside Paso Robles to recognize meaningful internal variation in climate and soils. Cabernet Sauvignon and Zinfandel dominate plantings, but Paso Robles is also one of California's most important regions for Rhône varieties — Syrah, Grenache, Mourvèdre, Viognier — and Tablas Creek, a joint venture with Château de Beaucastel of Châteauneuf-du-Pape, built its reputation on Châteauneuf-style blends grown here starting in the late 1980s.
