What type of wine is used in a Kir cocktail?

In a Kir cocktail, the primary ingredient is white wine. Traditionally, this cocktail is made by combining a dry white wine, such as Bourgogne Aligoté, with crème de cassis, a blackcurrant liqueur. The use of white wine provides a crisp and refreshing base that complements the sweetness and fruitiness of the crème de cassis. The combination results in a drink that is balanced and enjoyable, making it a popular choice as an aperitif.

Other types of wine, such as red, sparkling, or rosé, do not align with the traditional recipe for a Kir. Red wine would clash with the flavors of the crème de cassis, while sparkling wine might create an overly bubbly texture that's not characteristic of the classic Kir. Rosé could technically be used, but it’s not conventionally associated with this cocktail. Hence, white wine is the correct choice to create the authentic taste and experience of a Kir.
