Part of Fallet-Dart's 18 hectares of vineyards around Charly-sur-Marne is a special property in Drachy called Clos du Mont that "produces delicious and powerful wines." "Clos" in this context means a walled vineyard, which are mostly attributed to the abbeys of Catholic monks who once owned the land and originally planted the vines. Champagne's most famous example is Dom Perignon, the Benedictine monk credited with turning Champagne from a red wine region to the center of the sparkling wine world. Back to Clos du Mont. This premium grape growing vineyard is the source of Fallet-Dart's top wine, the 2004 vintage Clos du Mont Brut Champagne. However, Fallet-Dart produces two additional wines sourced from the Clos du Mont vineyard and the "Eocene" is one of them. The primary difference between the Clos du Mont and the Eocene is how long it's aged sur lie. Though not labeled as a vintage champagne, the Eocene is all from 2009, so aged for five years less than the Clos du Mont but that time on the lees produces an autolytic character of finesse and elegance. On the nose and palate, brioche, tart green apple, citrus, saline, pineapple and other tropical notes. I'm going to wrap up this review with a major wine geek fact: "Eocene" is the second epoch (55.8 million to 33.9 million years ago) of the Tertiary period (66 million years to 2.6 million years ago) and alludes to the system of rocks that were deposited during that time. Enjoy!
