Parker's Heritage Heavy Char Bourbon 10 Year is the 14th edition in this annual series from Heaven Hill named after the late master distiller Parker Beam. This Heavy Char Bourbon release is made from a mash bill of 78% corn, 12% malted barley, and 10% rye. The spirit is filled into 102 barrels which were charred for 1 minute and 30 seconds making them a level 5 char. Typically the distillery uses level 3 char barrels which are charred for 40 seconds. The barrels were aged on the 6th floor of Rickhouse Y. After 10 years of aging, the bourbon was cut to 120 proof without chill-filtration
