Europe and the US have reached a partial accord on their trade in wines. This should protect some of Europe’s most famous names from being used outside their true place of origin. Champagne, chianti, madeira are just some examples. The Washington administration says it will propose to congress that the European names be given clear status.Now they are considered almost generic in the U.S. In the future their use could be limited. Last year the Americans exported more than 400 million euros worth of wine to the EU. EU countries combined exported to the US almost 1.9 billion euros-worth.
