The 1er Cru Bois Chevaux sits mid-slope, facing east below the Clos Saint Pierre (monopole of Thenard) in a red, iron-rich soil. The vines are sixty to eighty years-old. Grapes are destemmed and fermentation (spontaneous, natural yeasts) takes place in large, wooden open top fermenters that are more than 100 years old. Aging takes place in large foudres and barrels, no new oak on this cuvee. Barrels are kept for approximately seven years. The foudres are very old.
