Which county is NOT part of the North Coast AVA?

The North Coast AVA (American Viticultural Area) is a renowned wine region in California known for its diverse climates and high-quality grape production. It includes several counties that contribute significantly to the state’s wine industry. Specifically, Sonoma, Mendocino, and Marin counties are part of this AVA, as they possess the climatic and geographical characteristics that define the North Coast region.

In contrast, Los Angeles County is situated much further south and is not included in the North Coast AVA. Instead, it has its own distinct wine regions that do not share the same climate or geological traits that characterize the North Coast. This makes the identification of Los Angeles County as not being part of the North Coast AVA correct, emphasizing the geographical boundaries that define the AVA and the counties it encompasses.
