By the late 18th century and through to the mid-19th, rum was a phenomenon. Rum drinkers could be found on every continent that touched the Atlantic. In parts of Africa and England, the spirit was actually used as currency. As the popularity of rum grew, so too did its production. In the Caribbean, dozens of distilleries on numerous islands were producing the liquor. Many elder distilleries added additional stills to increase production. Numerous distilleries created in this era remain famous to this day, including Mount Gilboa, today known as Mount Gay, and the distillery founded by Facundo Bacardi which bears his name.
