Grand Siècle is a Prestige Cuvée that is a unique concept, different from the others. It is the only Cuvée de Prestige in Champagne based on the blend and not on the vintage. Laurent-Perrier is convinced that by pushing the requirement for blending even further, it is possible to recreate the perfect oenological year, one that would put together the ideal balance from its different organoleptic components.
