Which ingredient is NOT typically found in a typical Screwdriver?

A typical Screwdriver cocktail is known for its simplicity, consisting primarily of two ingredients: vodka and orange juice. The essence of a Screwdriver lies in its refreshing blend of these two components, which create a citrusy and vibrant drink. While the presence of vodka and orange juice is essential to the identity of the cocktail, ginger ale is not a traditional ingredient. Including ginger ale would significantly alter the flavor profile and overall nature of the drink, making it more akin to a different cocktail altogether.

As for the aspect of garnish, many bartenders might serve a Screwdriver without any garnish, as it is straightforward and relies on the distinct flavors of the vodka and orange juice. This aligns with the clean and uncomplicated nature of the drink, where additional garnishes are not required to enhance its appeal. Thus, ginger ale is the ingredient that does not fit within the typical definition of a Screwdriver.
