What is the pour size for an Old Fashioned cocktail?

The pour size for an Old Fashioned cocktail is generally recognized as 2.0 ounces. This amount strikes a balance that allows the flavors of the whiskey, bitters, sugar, and any optional garnishes to come together harmoniously. The classic Old Fashioned typically features whiskey as the primary spirit, and the 2.0-ounce pour allows for a robust and rich flavor profile while being manageable within the scope of a single serving. This size also carefully considers the dilution that occurs from the ice used during mixing and serves to enhance the overall tasting experience of the cocktail.
