Ernest Hemingway needed a bathroom.

Or so the story goes. The novelist had stopped into Havana’s El Floridita bar, not far from the hotel where he lived during much of the 1930s. On his way out, he noticed the bartender setting up Daiquiris. Never one to walk past a drink, Hemingway took a sip. Not bad, he said, but he preferred them with no sugar and double the rum. The bartender made one as specified, and then named the drink after him.

A bar. A man. A drink. “Those are the facts,” writes drink historian Ted Haigh in “Vintage Spirits and Forgotten Cocktails,” “and from there the story goes straight to hell.”

The bartender may have called this drink the Papa Doble, which, with some ingredient additions, morphed into the Hemingway Daiquiri (or possibly the Hemingway Special or El Floridita #4). The exact history is a matter of considerable contention among cocktail sleuths, who have been poring over the clues ever since Hemingway walked out of the bathroom.
