Prepare the Fruit: Wash all fruits thoroughly. Thinly slice the lemon, lime, and orange. Core the apple and cut it into cubes. Hull the strawberries and slice them.

Combine Juices: In a large pitcher, combine the grape juice and thawed apple juice concentrate. Stir well to mix.

Add Fruit: Add the sliced lemon, lime, orange, cubed apple, and sliced strawberries to the juice mixture. Stir gently to combine.

Chill: Refrigerate the mixture for at least 4 hours, or overnight, to allow the flavors to meld and the fruit to infuse the juices.

Add Bubbles: Just before serving, gently stir in the chilled club soda or sparkling water to add a refreshing fizz.

Serve: Pour the sangria into glasses, ensuring each serving has some of the fruit. Enjoy this refreshing, non-alcoholic beverage!
