Tastes so much like a berry Kool-Aid. I like this best iced, when it reminds me of my childhood summers and pitchers of Kool-Aid in the fridge. It’s fun and pleasant, but I probably wouldn’t repurchase it or drink this too much (same way I never drink Kool-Aid anymore). It doesn’t have a very complex or interesting taste, if that makes sense, but it’s good for what it is, which is a sweet & straightforward berry tea. I don’t find it to be sour at all. I’d recommend if you’re into fruit teas or looking for something pleasant and caffeine free to ice.
