The pinnacle of the new collection, Trésor was crafted from a blend of around 100 eaux-de-vie, each selected for their finesse, depth, richness and length. This rarefied blend of spirits was then aged for more than two generations (50+ years) in special barrels famed for their age and rarity, called tierçons, within the Tesseron family's Paradis cellar (where the most valuable Cognacs are kept). Of course these eaux-de-vie are all Grande Champagne in origin, and all three major grape varieties (Ugni Blanc, Colombard, and Folle Blanche) are represented. This ensures the Trésor is comprised of only the best and most complex raw materials available.
