An elegant and simple cocktail combining dry brut champagne with sweet crème de cassis, perfect for celebrations and special occasions.
Keep all ingredients and glassware well chilled to preserve bubbles. Pour champagne slowly to avoid foam overflow. Adjust crème de cassis quantity to taste to avoid overly sweet cocktails. Serve immediately for best fizz. Substitute sparkling rosé for a pink hue or use sugar-free blackcurrant syrup for a lighter version.
