An extremely potent overproof rum with a fearsome reputation. It is sold under-the-counter (illegally) and usually available during sugar harvest time.
Many years ago while a practicing alcoholic, I was visit St Croix and a local friend told me about the Babash. I was in a bar I will not name and when they poured the shot, it came from a concealed bottle hidden beneath a mock other bottle- right on the back shelf. When I got the shot, it smelled of pure cane and molasses. Locals always watch the Americans drink it since most can't. Loved it.
