French Vermouth and Cassis Cocktail

Pro tips

• Use one large ice cube instead of crushed ice to slow dilution and keep the drink colder longer.
• Pour vermouth first, then cassis, so the liqueur settles and creates a layered visual effect.
• Chill your glass beforehand with ice water to extend the drink's temperature.
• Taste as you mix—vermouth brands vary in dryness; adjust the ratio if your vermouth is more herbaceous than expected.

Substitutions

• French Vermouth → Italian dry vermouth (drier, more herbaceous; slightly different flavor)
• Crème de Cassis → Chambord (deeper, more complex berry notes)
• Crème de Cassis → Crème de mûre (blackberry instead of black currant)

Equipment

jigger or measuring glass · bar spoon

Can I make this drink ahead of time?

No. Mix and serve immediately over fresh ice to preserve the vermouth's aromatics and prevent dilution.

What type of vermouth should I use?

Use dry French vermouth (blanc or extra dry). Avoid sweet vermouth, which will make the drink cloying.

Can I substitute the crème de cassis?

Crème de mûre (blackberry liqueur) or Chambord work as alternatives, though they shift the flavor profile.

How much ice should I use?

One large cube or 3–4 standard cubes, enough to chill without rapid over-dilution.

Is this drink served cold?

Yes. Serve immediately after mixing, while the ice is still solid and the drink is properly chilled.
