Legend says sailors drank the spirits preserving Admiral Nelson’s body after Trafalgar, giving rum the nickname Nelson’s Blood, though historians suspect the cask held brandy. This deep dive uses that myth as a doorway into rum’s heavy history. We start with ancient Austronesian sugarcane wines and Marco Polo’s notes, then move to 17th century Barbados, where enslaved people discovered that waste molasses from sugar refining could be fermented and distilled. A 1651 manuscript describes the result as kill-devil, a hot, hellish, and terrible liquor.

Rum became currency in the triangular trade, the largest manufacturing industry in colonial New England, and a spark for revolution after the Molasses Act of 1733 and the Sugar Act of 1764. We cover the Royal Navy ration that began after the capture of Jamaica in 1655, Admiral Vernon’s 1740 grog order, the tot that lasted until 1970, the surprising truth that pirates mostly drank stolen Spanish wine and brandy, and the 1808 Rum Rebellion that saw Governor William Bligh arrested in New South Wales. The episode then explains English, Spanish, and French agricole styles, the 10 percent tropical angel’s share, Jamaican overproof and John Crow Batty, and the modern legal battle over geographical indications between local distillers like Foursquare and European-linked companies like Maison Ferrand.
