Extra dry Champagne with little or none sugar dosage.
This rare "extra-brut" blend is made with carefully selected plots of Pinot Noir and Chardonnay grapes. It is a combination of a minimum of three vintages aged in oak. The "Ultra D" matures for a further four years before its release. With a low dosage of 2g/l, it is the purest expression of the "Cuvée D".
