27 years of age is a really long, long time for a bourbon.
I’m currently staring at a media review sample of the two decades and seven years old bourbon from Heaven Hill that predates a legendary fire there over 20 years ago. This fire, which gained a high degree of notoriety for the intensity of the burning, destroyed a staggering over 90,000 barrels of aging whiskey that had been produced at the Old Heaven Hill Springs Distillery before it was gutted in 1996.
