Ok. So I've read that the Blacktail bar in New York work with their own rum blend, to closer capture an authentic Cuban rum in the early 1900's. The blend consists of Bacardí Heritage, Caña Brava, Barbancourt white rum and Banks 5 Island. But does anyone know the ratio between all of these? Living on the other side of the world has made it difficult for me to waltz in and ask the bartenders. Any help would be appreciated, thanks!
