Jack Daniel's Gentleman Jack is a premium whiskey from the Tennessee region of Jack Daniel. It presents impressive complexity and flavor. It owes its uniqueness to a unique technique: double charcoal filtering once before maturation and again, several years later, before bottling. On the nose, oak, vanilla, charcoal, and apple are distinguished. Rich and full-bodied on the palate, it leaves a silky, warm sensation and a caramel aftertaste.
