Centrally located halfway between San Francisco and Los Angeles along California's famed Central Coast, Paso Robles is the third largest and most diverse wine region in the state. First established in 1983, today it boasts 11 viticultural areas with over 200 wineries ranging from small, family-owned producers to larger estates, making Paso a must-visit, wine-tourism destination. While the area grows numerous grape varietals, including Bordeaux and Rhone, and is known for its nontraditional blends, Zinfandel is the heritage wine grape, which is celebrated with the area's annual event, Vintage Paso: Zinfandel, in March.
