California's Napa Valley has been a source of world-class Cabernet Sauvignon for well over a century. Its warm climate and varied terrain allows for many styles of wine. One thread that runs through almost all the Cabernet based wines from Napa is their lush, ripe full-bodied feel and rich flavors of currant and berry. Wines from the valley floor, particularly around Rutherford, are famed for a dusty quality and those coming from the hillsides surrounding the valley, Mt. Veeder, Diamond Mountain and Howell Mountain for example, tend to be a little leaner with more obvious structural elements.
