Rare Perfection 14 Year from Preservation Distillery is made from a bourbon mash bill and aged in the freezing cold warehouses of Canada. Although technically Canadian Whiskey, it was distilled from a 4-grain wheated bourbon mash bill with just a hint of rye and malted barley. According to Preservation Distillery, the cold climate where this whiskey was aged has helped create its thick buttery body without the heavy lumber notes on the finish. This is due to the wood not expanding nearly as much in the cold northern climate.
