Which ingredient is not used in a White Wine Spritzer?

In a White Wine Spritzer, the primary ingredients are white wine and soda, which create a refreshing and lightly effervescent drink. Ice is often added to keep the drink chilled and enhance the overall experience. However, orange juice is not a traditional component of a White Wine Spritzer, which is why it is the correct answer. The classic composition prioritizes the combination of white wine and soda, minimizing the use of other flavors that could change the character of the drink. Thus, orange juice, while common in many cocktails, does not fit within the standard definition of a White Wine Spritzer.
