Rum production then moved to colonial North America, where the first rum distillery is thought to have been opened in Staten Island in 1664.
In 1655, the Royal Navy famously switched the daily liquor ration it gave to its sailors from
French brandy to rum. However almost a century later, in 1740, sailors’ tots of rum began to be watered down to prevent drunkenness, creating a mixture known as grog. This added lemon or lime juice to help prevent the onset of scurvy. Until 1970, the Royal Navy continued to give its sailors a daily ration of rum, and do so on special occasions to this day. The day the daily ration of rum ended is known as Black Tot Day.
