The Isobella is an underrated stirred cocktail that combines Canadian whisky with brandy and red vermouth. The blend of sweet mandarin liqueur and Galliano lends it a warm, almost marmalade-like depth, while the orange zest provides fresh accents. A drink that demands another sip after the first – perfect for cozy evenings or as a digestif after a heavy meal. The light effervescence of the soda water makes it more approachable than pure spirit blends.
You will need this for the Isobella
2 cl Canadian whisky
1 cl brandy
1 cl red vermouth (sweet)
0.5 cl Galliano
0.5 cl mandarin liqueur
Juice and zest of 1 orange
Chilled soda water (to taste)
Ice cubes
What matters
The orange zest is not just decorative: Rub the zest lightly over the rim of the glass before straining, then press it into the glass with the white side inward – this way, the oils release their aroma only when you drink. Use a fresh, untreated orange, as the zest comes into direct contact with the drink. Those who prefer a stronger aroma can rub the zest briefly in their hands first to release the oils. Add the soda water only at the very end, otherwise the drink loses its complexity too quickly.
Variations
- Isobella Dry — Replace the red vermouth with dry vermouth and reduce the mandarin liqueur to 0.25 cl. Instead, add 0.25 cl lemon juice to balance the acidity. Garnish: Lemon zest instead of orange zest.
- Isobella Spiced — Add 1 dash of Angostura bitters and a pinch of cinnamon to the mixing glass. Replace the Galliano with 0.5 cl honey syrup for a warmer, spicier variation.
Frequently asked questions
Can I replace the Canadian whisky with another whisky?
Yes, but the taste will change. Rye whiskey adds more spice, bourbon more sweetness. Scotch whisky or Irish whiskey will also work, but they tend to be smokier or milder. It’s important that the whisky isn’t too dominant – the brandy and vermouth should be able to shine.
Why is the Isobella stirred and not shaken?
Stirred cocktails like the Isobella don’t contain cloudy ingredients like juices or egg whites. Stirring keeps the mixture clear and allows the flavors to blend gently, without incorporating too much air. Shaking would dilute the drink too much and lose its elegant structure.
How much soda water should I add?
Start with 3–4 cl and taste after each addition. The Isobella shouldn’t be too fizzy – the soda water is only there to soften the sweetness and make the drink more refreshing. Too much water dilutes the flavors.
