The North Coast AVA is an American Viticultural Area in the state of California that encompasses grape-growing regions in six counties located north of San Francisco: Lake, Marin, Mendocino, Napa, Sonoma, and Solano. This large appellation covers over 3,000,000 acres (5,000 sq mi) and includes a number of smaller sub-appellations that all share the common ecology trait of weather affected by the fog and breezes off the Pacific Ocean.

Malbec is a purple grape variety used in making red wine. The grapes tend to have an inky dark color and robust tannins, and are known as one of the six grapes allowed in the blend of red Bordeaux wine. In France, plantations of Malbec are now found primarily in Cahors in South West France, though the grape is grown worldwide. It is also available as an Argentine varietal.
