Cognac is a region in Western France that also gives its name to a style of Brandy produced in the region. This is the only Brandy that can call itself Cognac if it is produced in the AOC of Cognac. The Cognac must be twice distilled in copper pot stills then aged for a minimum of 2 years in oak barrels from Troncais or Limousin. Most Cognacs spend far longer in the barrel than the minimum requirement.
