In 1995, the State of Chile approved the Wine Zoning and Designation of Origin through Decree No. 464 for wines produced in the country. Casablanca has been established as one of the designations of origin and occupies the territory that bears the same name. Since 2001, the Agricultural and Livestock Service of Chile (SAG), a governmental organization, began to implement, apply, and enforce this law. In 2011, the new classification for wine zoning and designation of origin was approved, allowing Chilean wines to divide their origin from north to south and east to west. Three new zones were then added: Andes, Entre Cordilleras, and Costa, in which the Casablanca Valley has been classified, featuring a great variety of terroirs.
