(Reuters) - Greek winemakers are not pricing their wares in drachmas - yet. The winemakers, visiting New York as part of an international promotional tour, doubted Athens would leave the euro-zone even after Fitch Ratings Agency downgraded Greece's sovereign debt on Thursday, calling the country's exit from the monetary union "probable." "No, no, no. That is not going to happen," Stellios Boutaris, whose family owns the Kir-Yianni winery, insisted. "And if that happens, we will have bigger problems than just pricing wine in drachmas."
