What spirit is used in the Blackberry Smash cocktail?

The Blackberry Smash cocktail is traditionally made with whiskey as its base spirit. Whiskey contributes a rich, warm flavor that complements the sweet and tart notes from the blackberries and any additional ingredients, such as mint and simple syrup, used in the cocktail. The combination of the whiskey’s complexity and the fresh, fruity profile of the berries creates a balanced and refreshing drink that is popular in mixology. Using other spirits like vodka, rum, or tequila would alter the foundational taste and character of the cocktail, making it less aligned with the classic Blackberry Smash recipe.
