How much Irn-Bru would the Royal Navy consume if it replaced the rum ration?
Short answerNo consumption total is given, but Irn-Bru is already stocked aboard Royal Navy ships.
NotesIrn-Bru already appears in Royal Navy ship stores. Alex Clarke recalls a friend at the manufacturer calling the service one of its largest customers. Replacing rum would therefore involve a drink already familiar aboard naval ships, though that recollection gives no consumption total.
