Which is not exported by the Republic of South Africa?

South Africa is a major exporter of several agricultural and mineral products, but coffee is not one of them. Coffee cultivation requires tropical conditions with warm temperatures, high humidity, and moderate altitude, typically found between the Tropics of Cancer and Capricorn in the so-called "coffee belt." South Africa lies mostly south of the Tropic of Capricorn, and its climate is too temperate and dry in most areas for commercial coffee production.

The other products are all significant South African exports:

• Wines - South Africa, particularly the Western Cape region around Stellenbosch and Paarl, is one of the world's major wine-producing and wine-exporting countries.
• Maize - South Africa is the largest maize producer in Africa and regularly exports surplus maize.
• Wool - South Africa has a large sheep-farming industry (notably merino sheep on the Karoo plateau) and is a leading wool exporter.

Coffee-exporting African countries include Ethiopia, Uganda, Kenya, and Tanzania, all located in tropical East Africa.
