Fermenting entirely in former Puligny-Montrachet barrels, the champagnes might as well be Chablis with bubbles for all their mineral-packed goodness. Dosages are very low (if at all) and the wines benefit from the restraint. None of these wines are fined or filtered. The Côte des Bar is located in the southernmost area of Champagne in the Pays d’Aube. Politically and geologically this subzone is as far as you can get from Reims and Épernay. Here the terroir is starkly different from northern Champagne and its famed chalky soils. In the Aube the terroir resembles that of Chablis – clay over Kimmeridgian and Portlandian limestone.
