Wines of South Africa (WoSA) is a fully inclusive body, representing all South African producers of wine who export their products. WOSA, which was established in its current form in 1999, has over 500 producers on its database, comprising all the major South African wine exporters.

It is constituted as a not-for-profit company and is totally independent of any producer or wholesaling company. It is also independent of any government department, although it is recognised by government as an Export Council.

WoSA is funded by a statutory levy per litre on all natural and sparkling wines exported.
