Within the cold, west-facing, Kimmeridgian limestone-rich lieu-dit of Biaunes, there is a small plot of Chardonnay that Gautherot planted wild: without preparing the soils and amongst the native vegetation (a totally crazy idea). The Côte des Bar is overwhelmingly planted to Pinot Noir, but in 2000 Gautherot chose Chardonnay. He used massale cuttings from Anselme Selosse’s vines (in Avize) and Vincent Dauvissat’s Valmur Grand Cru vineyard. This plot has become the base of what Antonio Galloni calls “one of the most beautiful and distinctive wines in Champagne.”
