This wine is produced only in the finest of vintages and is the product of the oldest vines (50 to 60 years of age) of the domaine. The vineyards consist of Oxfordian era limestone, are on very steep slopes at 230 meters altitude that afford excellent drainage and have full southern exposure. The fermentation occurs in temperature-controlled cuves, the first racking is done in July following harvest and the wine is bottled 20 to 24 months after harvest.
