The Bollinger La Grande Année is the pinnacle of Bollingers Champagne styles and is produced only in the best years. Fruit is sourced entirely from Grand Cru and Premier Cru vineyard sites in Champagne. The base wine was aged solely in old oak barrels, providing additional depth and nutty complexity. After secondary fermentation, the wine is aged on lees for more than five years before disgorgement. La Grande Année shows complexity and richness from the long ageing on lees and oaked base wines used in the cuve. The wine typically displays richness and depth of toast and bready characters, creamy palate texture, chalky minerality and great persistence. A vintage style it can be enjoyed upon release or carefully cellared for up to 10 years.
