Wine of Origin
The Wine of Origin system was created in 1973 and is administered by SAWIS, the
Suid-Afrika Wynbedryf-Inligting & -Stelsels. The area designations in order of decreasing size are Geographical
Units, Regions, Districts,
Wards and Estates. The latter four are always found inside a Geographical
Unit, but not necessarily nested inside a larger designation. For example the Goudveld Estate
is inside the Northern Cape Geographical Unit but not inside any Region, District or Ward.
