Hennessy Black, introduced in 2009, is a cognac made from young, fresh eaux-de-vies matured in old oak barrels in Cognac, France. Bottled at 43% ABV, it is made for the U.S. market.
But Hennessy Black suffers from its youth. The wood notes are rustic and have a turpentine character that really mars the finish. Not overly sweet like many young cognacs, it suffers from being too far on the other side of the fence. Stick with standard Hennessy.
