Does South Africa have a signature red grape?

It might not have been that clear cut 20 years ago but Chenin Blanc is now pretty much established as South Africa’s signature white grape. When it comes to the signature red variety, matters are more complicated. For a long while, there was a certain faction that argued vociferously that it should be Pinotage... but most view it as regional curiosity rather than the single key to unlocking global markets. This might seem to leave Cabernet Sauvignon pitted against Shiraz.
