Coppa Whiskey Sour Cocktail. The Whiskey Sour is one of the most famous classic cocktails of all time, withstanding the effects of prohitbition, which took many other classics into relative obscurity. The combination of whiskey, sweet and sour makes for a timeless taste, that is sure to please almost anyone. Whiskey Sour officially dates back to the 1860s, but sailors in the British Navy had been drinking something very similar long before that. On long sea journeys, water was not always dependable, so to combat that, spirits were often used. Scurvy, too, was another danger on these journeys, so lemons and limes were consumed to help prevent the disease (incidentally, this is also one of the reasons why British folk are called ‘Limeys’). Finally, sugar and water were added for taste. At this point, the drink is probably starting to sound familiar.
