What method is commonly used to mix an Old Fashioned?

The Old Fashioned cocktail is traditionally prepared using a muddling technique, which is integral to its classic preparation. Muddling involves gently pressing the ingredients together, which usually includes sugar, bitters, and a citrus slice (often an orange or a cherry), to release the flavors and aromas into the drink. By muddling, the bartender creates a balanced base for the cocktail that combines the sweetness of the sugar with the aromatic qualities of the bitters and the fresh notes of the citrus.

Once the ingredients are muddled, typically, a whiskey or bourbon is added, and the drink is served over ice. This method preserves the integrity of the flavors and allows the drinker to enjoy the essential characteristics of the Old Fashioned. It is crucial to note that muddling is different from shaking, stirring, or layering, which are other methods of cocktail preparation. Shaking would dilute and aerate the drink too much, while stirring is usually reserved for more delicate cocktails. Layering is a technique that creates distinct strata of liquid, which is not suitable for the Old Fashioned's intended presentation and flavor profile. Thus, muddling is the technique that aligns perfectly with the Old Fashioned's classic identity.
