Paso Robles is the largest American Viticultural Area (AVA) in California.
Answer: False.
The Central Coast is the largest AVA in California, covering nearly 6.8 million acres of land. At 612,000 acres, the Paso Robles AVA is the largest AVA within the Central Coast AVA. Currently, however, Paso Robles has just over 41,000 acres planted with vines.
