How to Make a Kir Royale Cocktail

A Kir Royale is a classic French cocktail made with just two ingredients: crème de cassis (a blackcurrant liqueur) and Champagne. It's elegant, simple, and takes less than two minutes to make. The deep purple hue of the cassis swirling through the fizzing Champagne makes it one of the most visually striking drinks you can serve.

The cocktail takes its name from Félix Kir, a former mayor of Dijon, France, who is said to have popularised it in the 1950s. The original version — known simply as a "Kir" — was made with white Burgundy wine rather than Champagne. Swap in the bubbles, and you have the Royale.

What you'll need

The beauty of this cocktail lies in its brevity. You only need two ingredients: crème de cassis and Champagne (or another dry sparkling wine, such as Cava or Prosecco). For the best results, use a good-quality cassis — cheap versions can be overly sweet and syrupy, throwing off the balance of the drink. As for the Champagne, it doesn't need to be expensive, but it should be dry (look for "Brut" on the label).

You'll also need a Champagne flute. The tall, narrow shape helps preserve the bubbles and shows off the drink's colour beautifully.

How to make a Kir Royale

Start by chilling your Champagne flute in the fridge or freezer for at least 10 minutes. A cold glass keeps the drink cooler for longer and helps maintain the fizz.

Once your glass is chilled, pour roughly 10–15ml of crème de cassis into the bottom — about one part cassis to seven parts Champagne, though you can adjust this to taste. Top slowly with chilled Champagne, pouring at an angle to minimise the foam. As the two liquids meet, the cassis will rise in gentle, violet-coloured ribbons through the glass. No stirring required.

Tips for getting it right

Always add the cassis first. Pouring the Champagne on top creates a natural mixing effect, so you won't need to stir and risk losing the bubbles. If you prefer a less sweet drink, reduce the cassis to 5ml. For a slightly richer version, add a small squeeze of fresh lemon juice to brighten the flavours.

Temperature matters more than most people realise. Both the Champagne and the glass should be well-chilled before you start. A warm flute will cause the Champagne to foam over quickly, and a warm drink loses its crispness fast.

Serving suggestions

A Kir Royale works beautifully as an aperitif — something to sip while guests arrive before a dinner party. It pairs well with light canapés, smoked salmon blinis, or a simple cheese board. The slight sweetness of the cassis complements savoury, salty flavours without overpowering them.

Garnish options are minimal by tradition, but a few fresh blackcurrants or a thin twist of lemon peel resting on the rim add a polished finishing touch. Keep it simple — this is a drink that speaks for itself.
