A very high proof rum drunk on Carriacou, famously dense enough that ice sinks in it rather than floating. It arrives at overproof strength and is drunk neat at boat launchings and wakes.
It is a distilled spirit sold at overproof strength; distilling without a licence is a criminal offence and this is not a preparation at all, only a bottling.
What goes into it
- overproof rum, imported at strength
- nothing else
How it is made
The rum is distilled elsewhere — historically in Trinidad — and shipped to Carriacou at overproof strength, where it is bottled and sold undiluted. The trick with the ice is real: at that alcohol concentration the liquid is less dense than water ice, so the cube goes to the bottom.
How long it takes: no ageing; sold as it arrives
How it is eaten
Neat in small measures, poured on the ground first for the ancestors, at boat launchings and wakes.
History
A Carriacou tradition imported at overproof strength and drunk neat at boat launchings and wakes on the Grenadine island.
