Although Château de Couches has within its grounds 83 hectares of vines including Pinot Noir, Chardonnay and Aligoté, the wine, sold under the brand Blason de Vair comes from all their local production. This terroir, spread over six communes, provides a technical diversity and a wide aromatic palette allowing, after strict selection, the creation of very different vintages, to the great pleasure of all those who love great Burgundy wines. Vinification is carried out by Côtes du Couchois wine-growers, in collaboration with Blason de Vair. Selection and blending is therefore carried out on the basis of an analysis of each of the batches presented, to create a vintage of around a thousand bottles.
