The 2016 release of Parker's Heritage that celebrates Heaven Hill's sixth-generation Master Distiller Emeritus Parker Beam, is this 24 Year Bottled-in-Bond Bourbon. It's comprised of bourbons from two different distilling seasons, one from Fall 1990 and another from Spring 1991. Since Mr. Beam's unfortunate diagnosis of Amyotrophic Lateral Sclerosis (aka ALS or Lou Gehrig’s disease) several years ago, the distillery has contributed over half a million dollars towards ALS research.
