Napa Valley Defined by mountain ranges and influenced by the proximity to the Pacific Ocean, the Napa Valley enjoys a temperate climate perfectly suited to the growing of fine wine grapes. The long growing season is marked by sunny, warm and dry days followed by cool evenings, an ideal combination for allowing grapes to ripen slowly and evenly. Home to some of the best wines in the world, Napa Valley is regarded as one of the best wine regions in the world to grow Cabernet Sauvignon. © 2003 Bennett Family Reserve
