Consultant Stephane Derenoncourt along with owner Olivier Bernard have done a fabulous job over recent years, but the tannic, backward 2010 Domaine de Chevalier seemed primary and difficult to assess when I tasted it on three separate occasions. The natural alcohol is 13.5% from a blend of 63% Cabernet Sauvignon, 30% Merlot and the rest Petit Verdot. A youthful inky/blue/purple color is opaque to the rim and the nose offers elegant aromas of crushed rocks, acacia flowers, boysenberries, black currants and subtle toast as well as oak. This thick, rich, tannic, backward wine will require patience. I would guess 7-10 years of cellaring will be essential, but this is a 30- to 40- year wine.
