There are regions of wine production in South Africa.  These regions are divided into districts and wards.  For a wine label to use the name of a region, district or ward, it must be made for 100% grapes of that area.

Red grapes account for approximately 45% of the grapes planted with Cabernet Sauvignon being the most widely planted. Other major red grape varietals include Syrah, Pinotage and Merlot. 

White grape varietals include Chenin Blanc, Colombard, Sauvignon Blanc, and Chardonnay.
