The Bollinger vineyard covers 179 hectares, most of which are classified as Grand or Premier cru. Pinot Noir predominates, a demanding grape variety with an intense character that forms the backbone of the Bollinger style. Continuity of style is ensured by an exceptional collection of over 800,000 reserve magnums, making Bollinger the only champagne House with such a wide and precise palette of aromas for their blends. As a guarantee of supreme quality, the best crus are vinified in wood thanks to a stock of 4,000 small, aged casks. The House lets its wines mature for twice as long as the appellation requirement. This is not out of vanity, but because a great wine needs the luxury of time to develop its full character.
