Korean Mulberry Juice

This mulberry drink actually tastes like it's namesake fruit, which I've found rare in the many fruit juices I've tried. It has a distinctly "planty" fresh taste, like you're chewing on a sapling. It's hard to describe the flavor of this drink to someone who has never tasted it or mulberry before. It's somewhere between apple, cranberry, raspberry, and birch. The birch is the weird part.
