Produced only in exceptional vintage years and intended as the ultimate expression of the Taittinger style, this wine is composed entirely of Chardonnay grapes grown in the top vineyards of the prestigious Cote des Blancs. Only the first press juice is used. A small proportion (5%) of the blend spends three to four months in new oak barrels, enhancing the intrinsic qualities of the final blend. Prior to disgorgement, the Blanc de Blancs is aged for 10 years on the lees in 13th-century chalk cellars that were once the property of Saint Nicaise abbey.
