Why was Bacardi 151 discontinued in the US?

Context: Bacardi 151 is a discontinued brand of highly alcoholic rum made by Bacardi Limited of Hamilton, Bermuda. It is named for its alcohol concentration level of 151 U.S. proof, that is, 75.5% alcohol by volume. This is much higher than typical rum, which averages around 35%–40% alcohol by volume. Bacardi 151 was sold in the United States and Canada from at least 1963 until 2016, when its production was discontinued.

Safety and lawsuits
Because of its high alcohol content, Bacardi 151 was particularly flammable among liquors. For this reason it was often used as the ignition source for "flaming shots" and even for at-home pyrotechnic stunts. The bottle carried a warning label advising consumers, among other things, "do not use this product for flaming dishes or other drinks." Bottles were also equipped with a stainless steel flame arrester crimped onto the neck of the bottle to prevent the rum inside the bottle from igniting. Nevertheless, Bacardi faced at least two lawsuits from consumers who claimed to have been badly injured by the product's flames. While the company never issued a formal statement regarding the product's discontinuation, it has been speculated that "it's a pretty good guess that Bacardi got sick of being sued."

Mixed drinks
Bacardi 151 was typically used in sweet drinks, such as the Hurricane and Caribou Lou, which combine rum and fruit juices.
