(Reuters Life!) - China, Russia and Brazil, where consumers are discovering the pleasure of wine, will power the growth of Italy's wine exports while the core U.S. market recovers, industry experts say. Wine exports from Italy, which competes with France for the position of the world's biggest producer, rose about 11 percent to 3.9 billion euros ($5.62 billion) in 2010, according to industry data, as markets recovered from the global downturn.
