Louis Delaunay

Louis Delaunay is a brand name, not a Champagne house. The bottle's NM-426-027 code traces back to SAS Les Roches Blanches in Oiry, on the Côte des Blancs, founded around 1993-1994 by the agronomist Nicolas Gueusquin and farming about ten hectares in Oiry and Dizy. Les Roches Blanches markets several private-label / retail brands - Jules Pierlot, Veuve Delattre, and Louis Delaunay among them - in parallel with its own Champagne Nicolas Gueusquin. The Louis Delaunay label is sold exclusively through the German retail channel (REWE supermarkets and the online retailer Weinfreunde.de). Honest competent négociant Champagne wearing an invented name for a retail aisle.
