La Jota Vineyard is a 28-acre estate on Howell Mountain in Napa Valley. It was started in 1982 by Bill Smith, an oil industry veteran, and his wife Joan. The couple bought a historic winery started in the late 19th century by a Swiss immigrant, Frederick Hess. The Smiths’ first winemaker was Randy Dunn. La Jota today is owned by Jackson Family Wines and the wines are made by Chris Carpenter. La Jota makes Cabernet Sauvignon, Cabernet Franc and Merlot.
