The Heritage Collection 17 Year Old Kentucky Straight Bourbon Whiskey by Heaven Hill is a remarkable testament to the distillery's relentless pursuit of excellence. This premium release is a blend of carefully selected 17, 19, and 20 year old barrels in a ratio of 28%, 44%, and 28%, respectively. It offers rich aromas of aged oak, rye, and toffee, with a complex palate of spice, vintage cigar box, and luscious ribbons of caramel. This bourbon has a mash bill of 78% corn, 10% rye, and 12% malted barley, and is bottled at 118.2-proof. Known in whiskey circles as the "Pappy killer," this bourbon's high quality and cult status make it a highly sought-after and tongue-in-cheek rival to the famous Pappy Van Winkle.
