Fireball

Fireball Cinnamon Whisky is a mixture of whisky, cinnamon flavoring and sweeteners that is produced by the Sazerac Company. With estimated sales of at least $150 million in 2015, it is the best-selling liqueur in the United States. Its foundation is Canadian whisky, and the taste otherwise resembles the candy with a similar name, Ferrara Candy Company's "Atomic Fireball" candy. It is bottled at 33% alcohol by volume (66 U.S. proof).
