As bourbon ages, a portion of the liquid is lost from the barrel due to evaporation—that's the "Angel's Share." After aging, when the bourbon is dumped out of the barrel, a certain amount of whiskey is left trapped within the wood of every barrel. That is called the "devil's cut." To create Jim Beam Devil's Cut, Jim Beam developed a proprietary process that actually pulls the rich whiskey trapped inside the barrels' wood after they're emptied. They hold the barrel-treated extract until it develops the proper balance of bourbon notes, then blend it with extra-aged bourbon and bottle at 90 proof. The result: a robust, premium bourbon with deep color, aroma and character. The taste is full bodied with intense oak and vanilla notes. It finishes long and smooth, with a hint of sweetness.
