The Vermouth Cassis is an underrated classic that combines the bitter elegance of dry vermouth with the sweet depth of crème de cassis. The soda water brings freshness without diluting the character – perfect as a light aperitif or a summery sundowner. Those who only know vermouth in a Martini will be surprised: the cassis makes it more approachable without sacrificing complexity.
And this is what you need for the Vermouth Cassis
5 cl dry vermouth (Dry Vermouth)
2 cl crème de cassis
10 cl chilled soda water
1 lemon zest (as garnish)
The key points
The cassis must be ice-cold – best stored in the fridge or placed in the freezer shortly before mixing. Why? Crème de cassis is viscous and would otherwise stick to the rim of the glass instead of distributing evenly. For an especially elegant touch, freeze the lemon zest for 10 minutes beforehand: this way it breaks cleaner when squeezed and releases more aroma. Only add the soda water at the very end – this keeps the fizz longer and keeps the drink fresh.
Variations
- Vermouth Cassis Spritz — For more lightness: shake 3 cl dry vermouth, 1 cl cassis and 2 cl lemon juice with ice, strain into a wine glass and top up with 8 cl Prosecco. Garnish with an orange slice.
- Herbal Cassis — Briefly swirl 1 cl absinthe or pastis in the glass, then fill with ice, 4 cl vermouth and 2 cl cassis. Top up with soda water and serve with a rosemary sprig garnish.
Frequently asked questions
Can I use sweet vermouth instead?
Yes, but then reduce the cassis to 1 cl, otherwise the drink will be too sweet. Sweet vermouth already brings enough sugar – the balance would otherwise shift too much toward the liqueur.
Why does my Vermouth Cassis taste flat?
Probably the soda water was added too early. Always mix the vermouth and cassis first, then top up with soda. Too much stirring after adding the soda destroys the fizz.
Is there an alcohol-free alternative?
Replace the vermouth with alcohol-free dry vermouth (e.g. from the aperitif category) and the cassis with alcohol-free cassis syrup. The soda water remains the same – the taste stays herbaceous and fruity, just without alcohol.
