The Kir is a classic French cocktail that is popular in Paris. It is made with white wine and crème de cassis, a blackcurrant liqueur. The combination of the fruity liqueur and the crisp white wine creates a light and refreshing drink. The Kir is often served in a wine glass and garnished with a lemon twist. It is a popular choice for aperitifs and can be found in many bars and restaurants throughout Paris.
