Kir and Kir Royale

This popular French aperitif of crème de cassis and white wine has long been a favorite in France, but it didn't get its name until after World War II.  Resistance hero Felix Kir, the mayor of Dijon from 1945 to 1968, was a huge fan of the cocktail, and whenever he entertained visiting dignitaries, he'd invariably serve them the drink. Kir did such a good job pushing the mixture onto his visitors that it eventually became inextricably linked with his personality, and that's why the cocktail bears his name today.  (Mental Floss)

"This is a French drink that can be mixed to taste. Use Champagne with the same amount of creme de cassis, and it is a Kir Royale."  ( All Recipes )

3/4 cup chilled dry white wine (such as a pouilly-fuissé)

4 teaspoons to 2 tablespoons crème de cassis liqueur (classically made to a rich rose' hue)

Mix & serve! 

While we're at it, here's the scoop on crème de cassis liqueur:  Crème de cassis is a blood-red, sweet, black currant-flavored liqueur. It dates back to the 16th century, first produced by monks in France as a cure for snakebites, jaundice, and wretchedness.
This cordial works well in pousse-cafés and some cocktails, but is most commonly mixed with just vermouth, white wine, or soda water. (The Webtender)
