Put the Kruškovac, the whiskey and the white wine vinegar with half of the ice cubes in a cocktail shaker. Shake for about 20-30 seconds. Now pour the grenadine syrup into the cocktail glass and add the remaining ice cubes. Carefully pour the cocktail over the ice cubes, creating a color difference between the golden yellow cocktail and the red grenadine syrup.
Perfect for a Game of Thrones evening or a red wedding.

Tip: If you like it fruity, you can swap the white wine vinegar for lime or lemon juice.
