Which cocktail is a variation of a Whiskey Sour?

The New York Sour is a variation of the Whiskey Sour that incorporates a layer of red wine on top of the cocktail. This addition of wine enhances the drink's complexity and adds a visual appeal with its distinct coloration. The base ingredients of both cocktails are similar, as both include whiskey, lemon juice, and simple syrup. However, the New York Sour sets itself apart by transforming the traditional Whiskey Sour into a two-tone drink, which not only alters the flavor profile but also elevates its presentation. This characteristic makes it an obvious derivative of the Whiskey Sour, demonstrating how variations can evolve by adding new ingredients while maintaining the essence of the original cocktail.
