Clark-Claudon Vineyards in Oakville, Napa Valley, was founded in 1993 by Thomas Clark and Laurie Claudon Clark. The couple had lived and worked in Napa Valley for 20 years as grape growers but eventually decided to make wine under their own name. The estate includes 18 acres of vineyards on the northeast side of Howell Mountain and produces Cabernet Sauvignon, Sauvignon Blanc and a Bordeaux-style blend.
