(Telegraph) - French winemakers are concerned their US competitors may be given permission to use the symbolic "chateau" label on bottles exported to Europe, destroying the meaning of the term. In France, wine labelled "chateau" is associated with a product entirely made from grapes grown on a "terroir" – a specific patch of land- giving it a unique identity and flavour. But a new proposal by the European Commission, to be addressed later this month, would allow American wines made with a mixture of grapes purchased from different growers, to use the title as well.
