Jefferson's Presidential Select Twin Oak 16 Years Old Kentucky Straight Bourbon WhiskeyThis bourbon, which started as a straight Kentucky Bourbon whiskey, was first fully matured for 11 years in new American Oak casks. From there, the bourbon was aged for an additional five years in fresh casks. The resulting product retains the bright notes found in a classic bourbon, but adds a depth of flavor and complexity that can be gained only through long years of extra aging in new barrels. Notes of orange spice, vanilla, tobacco and molasses
