The Old-Fashioned cocktail is a timeless classic and one of the most popular cocktails in bars and restaurants. It is a great drink to start with if you are just getting into cocktails, as it is easy to make and can be enjoyed by both whiskey and non-whiskey drinkers alike. It is a classic drink that has been around since the 1800s. The original recipe calls for whiskey, Angostura bitters, a sugar cube, and a splash of club soda. Many recipes today call for bourbon or rye whiskey, although other spirits such as brandy, rum, or gin can be used in place of whiskey.
