The assembly of this 2008 vintage is composed of 71% Pinot Noir and 29% Chardonnay. A total of 18 crus can be find in the blending, mostly Aÿ and Verzenay for Pinot Noir and Le Mesnil-sur-Oger and Cramant for Chardonnay. The fermentation is entirely in oak barrels. Bollinger R.D. is sold just a few months after being disgorged, with a very low dosage known as “extra brut”, at just 3 grams per litre. The recent disgorgement guarantees the remarkable freshness of the wine.
