Renowned throughout the world, the production of Cognac has been regulated by its very own AOC since 1909. Only liqueurs from eaux-de-vie made from crus from the controlled appellation area of Cognac can be labelled as such. This liqueur must be distilled and aged on-site in compliance with authorised techniques: double distillation in a copper Charentais still, ageing in oak barrels for a set minimum ageing period.
