The Corton-Charlemagne Grand Cru vineyards straddle the communes of Pernard Vergellesses and Aloxe-Corton and enjoy a south westerly exposure. The soil here is white marl, and almost pure limestone. Grapes are hand-harvested and then carried to the winery in small boxes, where they are sorted. Fermentation is carried out at 64-68°F in oak casks. Lees are stirred in the casks twice a week. Wines are aged in 50% new French oak barrels for 18 months.
