A Portuguese port tonic is a simple aperitif that pairs ruby or white port with tonic water, ice, citrus, and a fragrant herb garnish.
Plenty of ice and a gentle pour preserve the drink’s sparkle while the orange and rosemary bring out the port’s fruit and spice.

Chill the glass and tonic beforehand. Cold ingredients reduce dilution and keep the tonic lively.
Serving Suggestions
Serve before dinner with olives, almonds, salted almonds, or small seafood snacks. Use white port for a lighter, drier variation.

Recipe Notes
Make each drink to order. The tonic loses carbonation quickly once mixed, so do not batch the cocktail ahead of time.

- Bar spoon
- Citrus peeler
Ingredients
Port Tonic
- 2 oz ruby port chilled
- 4 oz tonic water chilled
- 1 cup ice large cubes
- 1 large orange peel wide strip
- 1 sprig fresh rosemary for garnish
Instructions
Build the drink:
- Fill a chilled wine glass with ice.
- Pour in the ruby port and top slowly with chilled tonic water.
- Give the drink one gentle stir to combine without flattening the bubbles.
Garnish and serve:
- Express the orange peel over the glass, rub it around the rim, and drop it in.

- Large ice cubes melt more slowly and keep the drink balanced.
- A dry tonic works well when the port is particularly fruity.
