I picked this up when I saw it at the store a couple weeks ago. I ended up getting a mix pack of Celestial Seasonings herbal teas as well.
This one is nice because you do just drop it in your cold water. The hibiscus is very present, but I don’t mind it like this. The flavour is fruity. It’s easy. It’s tastier than cold water, plain.
I like one bag in my very large mug (22oz?) but really whatever works, I just keep adding water during the day.
Big downside: the bags are plastic so they’re not compostable.
