Monterey County is situated on the Pacific Coast of California, divided between Santa Cruz and Monterey Bay Counties. Winegrowing areas in Monterey County take place mostly in the northern parts of the region. The cool climate that comes from the Pacific Ocean allows for the growth of exceptional Pinot Noir, Riesling and Chardonnay grape wines. The cool breezes from the ocean spread from north to south, bringing warmer weather in the southern areas, creating diverse climates and grape varietals in Monterey County.

Monterey County is home to forty nine grapes. About 50 percent of grapes grown in the region are Chardonnay. Monterey County has nine American Viticultural Areas – Monterey, Santa Lucia Highlands, Arroyo Seco, San Lucas, Hames Valley, Chalone, Carmel Valley, San Antonio Valley and San Bernabe. These areas are often termed as appellations deemed to be unique winegrowing regions that make up Monterey County.
