I followed the instructions on the box and used 1 sachet in 16oz boiling water for 5 minutes topped with 16oz ice cold water to cool it down. I had a glass with two ice cubes (maybe I’ll make tea cubes, but I drank it fast). The tea is a bright crimson with strong hibiscus flavor. Their is a herbal coolness underneath it, and a bright lemongrass tongue. I wonder what the cooling herbs used are, they definitely made me feel refreshed. The flavor isn’t one I’d request often, but I can see myself getting through 5 quarts of this due to convenience this summer. It’s nice to have an herbal iced tea option in the house.
