It was located in Moraga Canyon in the Santa Monica Mountains, in the hilly part of the upscale neighborhood of Bel Air in Los Angeles, California. Moraga Canyon was already home to wild grapes, as noted by Fr. Juan Crespí (1721–1782) in his diary during the expedition of Gaspar de Portolà (1716–1784) in August 1769. It was five miles from the Pacific Ocean, and 600 to 900 feet in elevation. It could be seen from Interstate 405 and from the J. Paul Getty Museum.
It was owned by film director Victor Fleming (1889-1949), who used it as a horse ranch in the 1930s and 1940s. Frequent guests to Fleming's estate were Clark Gable, Vivien Leigh, Ingmar Bergman and Spencer Tracy.
In 1959, it was purchased by Thomas V. Jones, who served as Chief Executive of the Northrop Corporation for thirty years, and his wife Ruth. They turned the estate into a vineyard, by planting a terraced vineyard in 1978. In 1986, they purchased additional adjacent land to expand the vineyard. In 2005, new winery facilities were built on site.
Under the brand Moraga Vineyards, it grew the following varietals of Bordeaux wine: Cabernet, Merlot, Petit Verdot, Cabernet Franc and Sauvignon blanc. It is grown on naturally deep gravel soil and annual rainfall of 24 inches. The first wine, the Moraga Red Table Wine, a blend of Cabernet Sauvignon and Merlot, was made by winemaker Tony Soter in 1989 and sold in 1992. The first Moraga White Table Wine was produced in 1998 and released in 2000. The current winemaker is Scott Rich.
The wines were served at the Bel Air Bar and Grill, Bel-Air Country Club, The Beverly Hills Hotel, Patina, Spago, and Morton's The Steakhouse. They have received good reviews from wine critics Jancis Robinson and Robert M. Parker, Jr..
