US wine exports no longer have permission to be labelled with traditional terms such as 'Chateau,' 'vintage' and 'clos,' after a clause in the wine trade agreement between the United States and the European Community lapsed.
A three-year extension was given to the US by the EC in order to give them time to cooperate with a previous ruling which banned US producers from using traditional wine terms considered specific to European wines. (Source: Decanter.com)
