Robert Moncuit's NV Blanc de Blancs is sourced from parcels of Chardonnay located in the villages of Mesnil and Oger. It is around 80% of its base vintage and 20% reserve wine from the preceding vintage.

Winemaker, Pierre Amillet's vinification style is consistent across all of his wines. He uses a combination of neutral oak and stainless steel in order to preserve the minerality and focus that Chardonnay grown in chalk can have. Around 80% of this release’s base vintage was raised in used oak while only 20% of reserve wine was. The dosage is 5 grams per liter.
