A term (also known as Méthode traditionelle or Méthode traditionelle classique) which is possible for all member states within the EU for a sparkling wine produced by the classical method of bottle fermentation. These designations may also be used in the national language. In contrast, Méthode champenoise is protected of origin and reserved exclusively for champagne. In the absence of these terms on the label, it is assumed that the sparkling wine was not produced by the classical method but by other methods such as the Méthode charmat (tank fermentation).
