What is the base ingredient for the Green Tea cocktail aside from whiskey?

The Green Tea cocktail, which typically includes whiskey, is known for its refreshing and slightly tart flavor that comes from its base ingredients. The correct base ingredient, aside from whiskey, is sour mix. Sour mix is a combination of lemon or lime juice and simple syrup, which adds a balanced acidity and sweetness to the drink, enhancing its overall flavor profile.

While peach schnapps might be a common ingredient in many cocktails, it is not typically associated with the Green Tea cocktail. Similarly, 7-Up, a soda, would alter the intended flavor notes significantly, and cranberry juice is not a standard component in this cocktail. The use of sour mix captures the essence of the drink's name, emphasizing its refreshing taste and the interplay of flavors with the whiskey.
