The Old Fashioned was born in the very early days of the Cocktail Era, around 1800.
But the first references can be found in the 1862’s book “The Bartender’s Guide” written by the one who is considered the father of bartending, Jerry Thomas. The recipe was called “Whiskey Cocktail” and it was mentioning “whiskey or wine” to be mixed together with sugar and bitter.
At that time was probably Rye Whiskey that became Bourbon during the Prohibition Era, when Rye Whiskey was scarce in U.S.
This bold and round spirit forward cocktail is a perfect after dinner, since the sugar settle the stomach and the alcohol and the bitters promote the digestion.
