France will ban winemakers from blending red and white wines to make rosé, even if the European Commission approves the practice as planned, French agriculture minister Michel Barnier has said.

France is the only EU member state that does not accept the new blending rule and "will do everything" it can to ban the practice, Barnier told French radio at the weekend.

Opposition from rosé wine producers in Provence and the French Government have forced the European Commission to offer a compromise deal, which would ensure that producers flag up use of the blending process on bottle labels.

Provence rosé winemakers, who account for 5% of world rosé production, use the more traditional maceration method and have voiced concern about a loss of quality for the category if the blending process is allowed.

The EU hopes to approve the blending technique by 1 August 2009.
