If you are a fan of Kentucky Straight Bourbon Whiskey and are familiar with Jim Beam Double Aged or the bourbon that succeeded it (XA Extra Aged), then you know Jim Beam Black Extra Aged. All that has changed over the years is the labelling. Why mess with success? A NAS Kentucky Bourbon that is distilled from a mash bill containing 77% corn, 13% rye and 10% malted barley and aged for approximately 6 years in first run charred white oak barrels, Jim Beam Black Extra Aged has a heavy woody taste accented with notes of sweet caramel and vanilla.
