In the heart of the Mayacamas and Vaca Mountain ranges, just 20 miles north of the Napa Valley, stands a pristine wine country that has quietly been growing outstanding wine grapes for a very long time. Lake County, California rises above the rest of the world in more ways than one. It boasts the cleanest air in California, the oldest lake in the continental United States, and a variety of splendid soils whose contents range from volcanic to alluvial. The region is best known for world-class Sauvignon Blanc and Cabernet Sauvignon, but plenty of other varieties thrive in this diverse and unique terroir.
