The Prosecco DOC Consortium, charged with protecting, upholding and promoting the standards of prosecco since its DOC acquisition in 2009, announced 18% export growth in 2013 at 155 million bottles worldwide. Its largest markets are United States, Germany and United Kingdom. Overall, prosecco was the top-selling sparkling wine in the U.S. last year. The DOC label represents 30% of the total prosecco market, “a great achievement in the sparkling wine category,” said Stefano Zanette, president and chairman of the Consortium.
