How to Make Refreshing Pomegranate Iced Tea?

I’m looking for a recipe to make a refreshing Granatapfel Eistee (pomegranate iced tea) at home.

What’s the best way to balance the tartness of the pomegranate with sweetness? Should I use fresh pomegranate juice or is bottled juice fine? Any tips for adding extra flavors or garnishes to elevate the drink? I’d love to hear your ideas!
