NitroX...get thee to the Cape Region, and any tour operator will be able to hook you up with a wine region tour. Areas you might want to include in you tour would probably include Paarl, Stellenbosch, Franschoek among others. There are many, many good wineries in the Cape. KWV is among the largest CO-OPs there, and is a large commercial operation, although they do produce some excellent wines. If you have a couple of days to spend in the area, on day one I would visit a high end wine store in Cape Town, talk to the owner, and perhaps he or she could hook you up with a private tour.
