Cognac named after the town of Cognac in France, is the most famous variety of brandy, produced in the wine-growing region surrounding the town from which it takes its name, in the French Departements of Charente and Charente-Maritime. The town of Cognac is one of only three officially demarcated brandy regions in Europe; the others are the French town of Armagnac and the Spanish town of Jerez.

According to French Law, in order to bear the name, Cognac must meet strenuous legal requirements, ensuring that the 300-year old production process remains unchanged. It must be made from at least 90% Ugni Blanc, Folle Blanche, or Colombard grapes, although Ugni Blanc, specifically Saint-Emilion grapes, are today virtually the exclusive variety used. The remainder may consist of the grape varieties Folignan, Jurançon blanc, Meslier St-François (also called Blanc Ramé), Sélect, Montils, and Sémillon,  It must be distilled twice in copper pot stills and aged at least two years in French oak barrels, from the Limousin or Troncais forests, and the barrels must be sealed airtight.
