Bollinger
The house was founded in 1829 in Aÿ and is among the few major Champagne houses still in family hands. Its distinctive style is characterized by the significant proportion of Pinot Noir in the blends and the fermentation of reserve wines in small, used oak barrels.
Reserve wines are stored in magnums under cork, a condition that slows their evolution and enriches the blends in subsequent years. La Grande Année is released only in declared vintages, with long aging on the lees.
The abbreviation R.D. stands for récemment dégorgé (recently disgorged): it shares the same base as La Grande Année, but with a much longer period on the lees and late disgorgement. Controlled storage, traceable origin.
