Cognac, Armagnac, Brandy… different names for a similar product. But certainly not the same. Named for a town in France where it is produced, Cognac is often considered to be the best. Distilled from wine on a pot still and then aged at least two years in French Oak, cognac is sweet, rich and nuanced. It is classified according to age. VS- for a minimum of two years, VSOP- for a minimum of four, XO or Napoleon- at least six years, and Hors d'Age- Even. More. Old.
