I don't believe they offer wine flights (though I could be wrong and often am), but I've found their servers to be quite knowledgeable about the wines they offer, and I'm certain your server would be more than happy to suggest wine pairings with whatever courses you choose.
S. Africa does have some excellent wines, though I'm partial to their whites. Some of their reds (none I've had at Jiko, however) have a tendency to possess notes of burnt rubber or tar on the finish. On the other hand, I find most of their white wines to be delightful and full of flavor. Have fun!
