Aged, as Albert Tesseron puts it, “for one generation” (meaning 25-plus years) the Extra Légende was created from a blend of Tesseron Grande Champagne reserve wines. Its deep complexity was built around the inclusion of around 50 eaux-de-vie (including a number made from the Folle Blanche variety, a rarity in Cognac today) and its maturation in cellars of different humidity levels.
