The vast North Coast AVA in the US state of California extends northwards from San Francisco and includes some of America's most important and distinctive wine regions. Many are entitled to use their own prestigious appellations on wine labels. As a result, high-volume commercial wines, sourced from grapes grown throughout the region, are the main users of the North Coast AVA.
The Pacific Ocean influences the climate here by creating cool coastal air and fog which help to lower the temperature – especially in sub-regions where valleys funnel the cooler air inland. Annual rainfall is also higher than in many other American wine regions. These conditions are ideal for growing quality grapes for premium wine. Chardonnay, Cabernet Sauvignon, Merlot, Sauvignon Blanc and Pinot Noir are amongst the varieties which thrive here.
