The Kir cocktail is a popular French apéritif made with crème de cassis (blackcurrant liqueur) and white wine. It was created by Félix Kir, a Catholic priest and mayor of Dijon, France, who served the cocktail at official events in the 1940s and 1950s to promote the local wine industry.
The cocktail is typically served in a wine glass and is named after its inventor, although it is sometimes referred to as a Kir Royale when made with champagne instead of white wine. Today, the Kir cocktail is enjoyed all over the world and has become a classic of French cuisine.
