What is the main ingredient in a White Wine Spritzer?

The main ingredient in a White Wine Spritzer is white wine. A White Wine Spritzer typically consists of white wine mixed with soda water or sparkling water, which adds effervescence and a refreshing quality. The use of white wine is fundamental to the drink's identity, as it provides the primary flavor profile.

In this cocktail, the type of white wine used can greatly influence the taste, with options ranging from dry to sweet wines. The addition of soda water lightens the drink, making it popular for warm weather or as a refreshing aperitif. Understanding that white wine is the cornerstone of this beverage helps clarify why it is the correct choice among the other options, which do not match the foundational requirements of the spritzer.
