There are many stories in history of the wrong thing happening at the right time. According to Andrew Friedman in Gary Regan's book The Negroni, grabbing the wrong bottle while making a Boulevardier added apple brandy to the cocktail instead of rye whiskey. A star was born in the Mela d'Alba, and the subject of Day 41's of #100DaysOfCocktails.
When it was apparent that the three mile international border was being used as a staging ground for drunken revelry during Prohibition, Congress pushed the border out to twelve miles. This discouraged small boats from smuggling, but encouraged Tommy Millard to create the Twelve Mile Limit cocktail.
Not for the faint of liver, the Mississippi Punch is an amazingly smooth sipper with one hell of a kick. It is also typical of cocktails in the 19th century that were heavy on the liquor and lighter on the mixers. #100DaysOfCocktails celebrated a little on National Punch Day with a single serving powerhouse.
Orange curacao was relatively new in the mid to late 19th century. It became a popular sweetener as bartenders were fleeing the country before Prohibition. Harry MacElhone created a delightful cocktail, the Sidecar, in his New York Bar during that dry time. #100DaysOfCocktails take a look at this incredibly well balanced drink.
