As recently as 1995, a joint association including the Servicio Agricola Ganadero, the Ministerio de Agricultura and Chilean wineries established Chile’s first set of wine regulations. They established boundaries for regions, sub-regions and appellations, as well as wine label regulations, which include:
If a wine label carries the name of a place, such as a region, sub-region or appellation, 75% of the grapes must come from that place.
When a wine label carries the name of a grape variety, the wine must be made from at least 75% of that grape variety.
If a wine label carries a vintage, 75% of the wine must come from that vintage.
