Cognac, named after the town of Cognac in France, is the most famous variety of brandy. It is produced in the wine-growing region surrounding the town from which it takes its name, in the French Departements of Charente and Charente-Maritime.
According to French Law, in order to bear the name Cognac, the production methods for the distilled brandy must meet defined legal requirements, ensuring strict conformity with the 300-year old production process. It must be made from at least 90% Ugni Blanc, Folle Blanche or Colombard grapes; of these, Ugni Blanc, known locally as Saint-Emilion, is the most widely-used variety today. It must be distilled twice in copper pot stills and aged at least two years in French oak barrels from Limousin or Troncais.
