Most recently popularized by removing the distillate from the original barrels and aging, or finishing, in different barrels for a short time prior to bottling. In the case of Woodford Reserve Double Oaked, the distillate was taken from original virgin oak barrel and finished in a new virgin oak barrel to enhance some of the oak flavors like caramel and vanilla. Another method is to start in a used whiskey barrel and then finish in a barrel that contained sherry, such as Power’s Signature Release Irish Whiskey Or Macallan Double Cask .
