Fireball Cinnamon Whisky is a mixture of Canadian whisky, cinnamon flavoring and sweeteners that is produced by the Sazerac Company. 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 .
According to the official Fireball website, the product was developed in Canada in the mid-1980s, and for a long time was little known outside of Canada.
As of 2018, Fireball is among the top selling whisky-related brands in the United States. In addition to the United States and Canada, Fireball is now also available in other countries.
