100% Chardonnay from exclusively Grand Cru parcels. The blend draws 60% from Aÿ (Grand Cru, Vallée de la Marne) — chalky hillside sites that bring unusual mineral intensity and body to the wine, rare for a Blanc de Blancs — and 40% from three Côte des Blancs Grand Crus: Avize, Cramant and Oger. Non-vintage with 30% reserve wines. Partial malolactic fermentation preserves the vivid acidity and freshness of the Chardonnay.

Maison Lallier, founded 1906 in Aÿ and owned by Campari Group since 2020. Chef de cave Dominique Demarville previously spent 13 years as chef de cave at Veuve Clicquot. Aged 36–48 months on lees, dosed at 8 g/L. Rated 91 pts Wine Enthusiast · 91 pts Decanter · 92 pts Falstaff.
