“Chuflay” refers to a Bolivian drink. The name has been used ever since the day an English train driver of the Bolivia Railway Co., who used to enjoy his whisky or gin with ginger ale in the dining car, realized that his bottles had been forgotten. Concerned, the waiter offered him a “Llallagua” instead. The name of this singani-based drink with soda, ice and lemon stems from a tin mine, whereas singani is a typical Bolivian muscatel brandy. Not being familiar with this beverage, the train driver rejected it for fear of a hangover until his craving got the better of him. The next day, not having experienced any hangover symptoms, he commented “sure fly” when ordering his “Llallagua”. CHUFLAY is how the waiter, who spoke no English, ended up pronouncing it.
