Kir Royale – Champagne & Crème de Cassis French Sparkling Cocktail

A Kir Royale cocktail keeps things simple: chilled Champagne, a small pour of crème de cassis, and nothing else required. The cassis brings dark blackcurrant fruit and a touch of sweetness, while dry Champagne keeps the finish lively and crisp. Built directly in a flute, it works especially well as an aperitif, a toast, or a low-effort sparkling serve for a crowd.

From Burgundy's Kir to the Royale

The Kir Royale grew out of the Kir, the Burgundy aperitif made with dry white wine and crème de cassis. The drink became closely associated with Canon Félix Kir, mayor of Dijon after World War II, who promoted local Burgundy products at official receptions. In the Royale variation, Champagne replaces still white wine. The IBA recognizes this Champagne substitution in its official Kir specification.

What You'll Need

Ingredients

• Champagne: Provides the dry, sparkling backbone and crisp acidity.
• Crème de Cassis: Adds concentrated blackcurrant flavor, deep color, and measured sweetness.

Substitution tip: Dry Crémant or Cava can replace Champagne for a practical sparkling variation, though it is no longer a strict Kir Royale. For a raspberry variation, replace the cassis with crème de framboise or Chambord to move toward a Kir Impérial rather than treating it as a direct substitute.

Equipment

• Champagne flute
• Jigger

Two Ingredients, Clear Contrast

The appeal comes from the balance between dry bubbles and concentrated blackcurrant liqueur. Champagne keeps the drink bright and lively while a relatively small measure of cassis adds enough fruit to change the aroma, color, and finish without turning the drink syrupy. There is no shaker or mixing glass to manage, so ingredient temperature and proportion do most of the work.

Substitutions & Variations

• Make it drier: Reduce the crème de cassis slightly for a more restrained blackcurrant note.
• Use another dry sparkling wine: Crémant or Cava works well when Champagne is unavailable, though the result is technically a sparkling Kir variation rather than a strict Kir Royale.
• Make a Kir Impérial: Replace crème de cassis with raspberry liqueur while keeping the Champagne.
• Skip the garnish: The drink does not require one. A raspberry or lemon twist can be added when you want a visual or aromatic accent.

Helpful Tips

• Chill both the Champagne and the flute before building the drink.
• Add the crème de cassis first so the Champagne helps distribute it naturally.
• Pour the Champagne slowly to control the foam and preserve carbonation.
• Do not stir unless absolutely necessary. The rising bubbles will help integrate the drink.
• For several servings, portion the cassis into chilled flutes ahead of time and add Champagne immediately before serving.
• Serve with oysters, smoked fish, mild cheeses, or other salty aperitif snacks that contrast with the cassis.
