In a large pitcher, combine the cranberry juice, fresh orange juice, and lime juice. Stir well to ensure the flavors are fully integrated. Using fresh citrus juice makes a world of difference in the brightness of the final drink.
Add your simple syrup or maple syrup to the juice mixture. Stir vigorously until the sweetener is completely dissolved. If you prefer a more tart drink, you can reduce the amount of syrup used.
Add the ice cubes to the pitcher or directly into individual serving glasses. Stir the juice base one more time to chill the liquid before adding the carbonated element.
Just before serving, pour in the ginger ale or sparkling white grape juice. Stir very gently with a long spoon to mix the flavors without losing the carbonation. This ensures every sip is bubbly and refreshing.
Pour the mocktail into glasses. Garnish each glass with a few fresh cranberries, a slice of orange, and a sprig of fresh rosemary. The rosemary adds a wonderful pine-like aroma that enhances the holiday experience.
