This glass bourbon bottle Christmas ornament is labeled Whiskey Kentucky Straight Bourbon. Most brands of bourbon are produced in Kentucky, where bourbon production has a strong historical association. Bourbon whiskey is a type of American whiskey, a barrel aged distilled spirit made primarily from corn. Jim Beam is the world's top brand of Kentucky straight bourbon. Bourbon is served straight-up, with water, over ice, or mixed with soda and into cocktails. If you know someone who likes to drink a Manhattan or an Old Fashioned, this is a cool ornament that they will love to hand on their tree.
