Cognac

In particular, it must be made from specified grapes, of which Ugni Blanc, known locally as Saint-Emilion, is the one most widely used at the present time. In addition, the brandy must be twice distilled in copper pot stills and aged at least two years in French oak barrels from Limousin or Tronçais. Cognac matures in the same way as whiskies and wine when aged in barrels, and most cognacs are aged considerably longer than the minimum legal requirement.
