The tea I am trying to recreate was sweet without any added sugar, it was a rich red-ish brown (could mean it had hibiscus), had a strong orange flavor (added citrus oils?), and was herbal...so no actual tea leaves.
I know some of my sweet herbasl teas have stevia leaves in them. Just throwing that out there, I don't create many teas for myself, and if i do, they are very basic.
I sometimes add a tiny bit of mint to my tea blends to get that cool refreshing flavor, but not enough to even recognize the mint as a flavor, plus I always have soooooo much mint. lol.
