Why Did Pirates Drink So Much Rum at Sea?
Pirates did not drink rum because they liked it. They drank it because the water stored in wooden barrels in Caribbean heat was a bacterial hazard that had killed men on every voyage before this one, rum was the accidental waste product of Caribbean sugar production that cost almost nothing, and mixing the two in the right ratio killed enough bacteria to make the water survivable. Nobody on board knew why it worked. Germ theory would not exist for another hundred and fifty years. They just knew that men who drank their water mixed with rum died of dysentery less often, and on a ship where a sick crew meant a dead ship, that observation was everything. This is the full story of why pirates drank so much rum at sea — the accidental origins of rum as distilled sugar waste that Caribbean plantations could not give away, the bacterial reality of fresh water stored in tropical heat for weeks, the disinfectant mechanism that the rum was performing without anyone understanding it, the dilution ratio that pirates were using a generation before the Royal Navy formalised it as grog, the written pirate codes that actually limited drinking rather than encouraged it, and what chronic rum consumption was doing to the bodies of the men who depended on it in ways that nobody could have described in 1715 but that experienced captains were compensating for through observation alone.
