Wine regions of South Africa
The wine regions of South Africa were defined under the "Wine of Origin" (Wyn van Oorsprong) act of 1973. Mirroring the French Appellation d'origine contrôlée (AOC) system, all South African wines listing a "Wine of Origin" must be composed entirely of grapes from its region.
