Mendocino County is a northern California wine region located above Sonoma County, with vineyards shaped by Pacific influence, inland valleys, mountain terrain, and significant organic and sustainable farming traditions. Its geography ranges from the cool Anderson Valley near the coast to warmer interior areas such as Redwood Valley, Ukiah Valley, and Potter Valley.
The county is best known for Pinot Noir, Chardonnay, sparkling wine, Zinfandel, Cabernet Sauvignon, Petite Sirah, and aromatic white varieties, depending on site and climate. Mendocino’s importance lies in its contrast between coastal freshness and inland ripeness, giving the region a broad identity that is less commercially dominant than Napa or Sonoma but highly distinctive within California wine.
