The Blanc de Blancs is mainly Chardonnay with a touch of Weissburgunder. Sourced from sites in Ingelheim, the grapes were direct-pressed with fractioning used to focus on the cuvée. The end of the press, or taille, is not used. The BdB saw aging mostly (about 2/3) in used tonneaux with no fining or filtering. Post tirage, the wine spent 24 months on the lees and has a dosage of 2 grams.
