Wine Advocate-Parker : Fermented in oak barrels and aged under natural corks for almost 13 years, Bollinger's 2004 R. D. Extra Brut blends 66% Pinot Noir with 34% Chardonnay from 16 crus, 88% of which are classified as Grand Cru. The wine opens with a very clear, deep, rich and aromatic but also pure and mineral-fresh nose of crushed rocks, cherries, brioche, pain aux raisin, white nougat, chalk and ripe, yellow-fleshed fruits. Highly elegant and complex on the weightless yet persistent and salty palate, this is an intense, densely woven, firmly structured yet elegant, beautifully refined and refreshing recent disgorgement (February 2018) that reveals just a kiss of oxidative flavors that adds even more complexity. A great Champagne on its way to improve over many years in the bottle. Tasted June 2018.
