What is the key flavor in a classic Bellini?

The key flavor in a classic Bellini is peach puree. This cocktail originated in Venice, Italy, and is traditionally made by combining Prosecco with fresh peach puree. The use of ripe, sweet peaches not only provides the distinctive flavor profile of the Bellini but also contributes to the drink's smooth texture and natural sweetness. Peach puree captures the essence of summer and is integral to defining the cocktail, making it refreshing and fruity.

While other fruit purees or juices might be used in variations of the Bellini, such as strawberry or pineapple, they do not represent the classic or authentic formulation of the drink. Lemon juice is typically associated with sour cocktails and does not complement the sweet and fruity characteristics of the Bellini. Thus, peach puree stands out as the essential flavor, providing the foundation for this iconic cocktail.
