Henry McKenna was an Irish immigrant that new how to distill a mean whiskey. This bad boy is bottled in bond, meaning that it has to be at least 4 years old (it’s 10) and that it has to be bottled at 100 proof, or 50%. It’s an insanely good bourbon, especially for this price. It won four awards in the San Fransico World Spirits Competition: double gold, best bourbon, best in show whiskey and best single barrel bourbon. Not bad. Not bad at all.
