No I have not, but I can tell you the best wine is the ones without a label..know a wine maker up near Stellenbosch, he makes his own special brew of red, the best I have ever had, so every year a get a few to stack away.
Used to LOVE a good Pinotage with a T-Bone... And the Shiraz with a lighter meal. Got some favorate brands, but then suddenly one night got allergic to red wine... can't explain it, can drink half a glass and feel like a train hit me... So keeping to good old white wine now :(.... and my fav is funnily enough some of the cheapest. St. Anna's! :)
