(AFP),South Africa — The busload of Swedes sweep onto the 326-year-old South African wine farm for a wine tasting visit that marries vineyard tourism with bottom-line marketing. Sweden is now the third biggest buyer of wine from South Africa, one of the countries the industry is courting to counter a tough export climate. "At the moment it's somewhat stable but you have to fight for every piece of pie out there. The market is tough -- it's not an easy market," said Boschendal's Jamiel Ryklief after welcoming the tourists to the stately estate.
