Special Cuvee is made from a majority of reserve wines fermented either in mature oak casks or small stainless steel tanks depending on the characteristics and fundamental potential of the base wines.

A significant part of the reserve wines have been fermented in mature oak barrels before being transferred into magnums, which are then stored under cork in Bollinger's cellars for as long as 12 to 15 years, with a minimum of 5. Blended some years later with the other base wines, coming from the two latest harvests in proportions which can change from one year to another, they impart the final blend with an inimitable and unrivaled consistency and majesty.
