In a statement the brand said: “For this grande cuvée Lanson has combined two essential elements of its expertise: a blend of grand crus and the marriage of three exceptional vintages.
“The general fruitiness of the Pinot Noirs from Verzenay and Bouzy is tempered by the delicacy and extreme finesse of the Chardonnays from the Côte des Blancs.”
