Montgueux lies in between Côte de Sezanne and Côte des Bar. It is the only village in the Troyes region authorised to produce champagne. In the past, this chalky outcrop surrounded by plains was known as the “Montrachet" of the Champagne region. It has to be said that the Chardonnay expresses itself beautifully here and as in Montrachet, the grapes have to be very ripe. Emmanuel Lassaigne has skilfully continued the work of his father Jacques. Every cuvée shows that although it is off the beaten track, the village of Montgueux is well worth a detour. Domaine Jacques Lassaigne owns 5.7 hectares of vineyard. His son, Emanuel Lassaigne now manages the domain. These champagnes are full of character and fully express the terroir. Jacques Lassaigne is a firm believer in respecting nature and tends to each vineyard parcel meticulously. Chemical fertilisers and sulphites are avoided completely.

Lassaigne's Brut Nature is a rich Blanc de Blancs champagne with aromas of mandarin, pear and melon.
