151 proof rum

151 proof rum, also known as overproof rum, is usually dark, aromatic rum from Guyana and the West Indies that have been bottled at higher proof than usual rum.
Bacardi 151 is probably the best known brand. Overproof rum is not available in several countries because of its high alcohol content. Regular dark rum can be used instead.
Overproof rum is usually used floated, and sometimes ignited, on top of shots. It is also used in punches and high proof cocktails.
Warning: 151 proof rum is very potent and should not be drunk straight. Be extremely careful when using 151 proof rum for flaming drinks.
