A small and very well-run co-operative in Champagne, in the Sézanne area of the Marne. Founded in 1963 by 20 producers it now has 150 members. The name derives from the Le Brun de Neuville family who had a long history of winemaking in the region and who, in the 19th century, established the house that has become the cooperative.
The 150 members farm 150 hectares between them, almost 90% of which is chardonnay, and the co-operative urges all of them to farm sustainably. The vineyards themselves include crus at Villenauxe-la Grande, Fontaine-Denis, Barbonne-Fayel, Chantemerl and La-Celle-sous-Chantemerle.
