Cuba Libre cocktail would have been born just after the second war of independence which ended in 1898 and which opposed the U.S.A. to Spain. After 1898, the Americans still occupied Cuba, and in 1900 cola was now on sale there. It would be during this same year that a captain accompanied by his troops would have ordered a rum accompanied by cola and a slice of lemon, before exclaiming "Por Cuba Libre!".
This story would be more plausible but the origin remains as mysterious and uncertain as ever, just like the rum used at the start. Two major brands of rum (Bacardi and Havana Club) of course each claim to be the one originally used.
The Cuba Libre is sometimes ironically called in Cuba "mentirita" or "mentiroso", meaning "little liar" or "liar" by those who do not consider Cuba free, but the Cuba Libre can also be seen as a sign of hope .
