Which ingredient is used in a Chilled Grape Crush cocktail?

In a Chilled Grape Crush cocktail, vodka is the primary ingredient. Vodka serves as the base spirit, providing a neutral flavor that allows the other elements of the cocktail to shine, particularly the grape flavoring. The light and clean profile of vodka complements the fruity notes without overpowering them, making it an ideal choice for this refreshing drink. Other spirits like cognac, whiskey, or tequila would introduce their own distinct flavors, which could detract from the intended profile of the Chilled Grape Crush. This cocktail is often enjoyed for its fruitiness, and the use of vodka enhances that characteristic while keeping the drink light and crisp.
