The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the "Malibu Coast" viticultural area, which covers approximately 44,590 acres in portions of Los Angeles County and Ventura County, California. The viticultural area includes the established Saddle Rock- Malibu and Malibu-Newton Canyon viticultural areas. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase.
