Decaf. Can’t taste the black tea. Has some spices in it, maybe cinnamon? I don’t think this is real lemon. Maybe lemon grass. I almost never add lemon to tea. This does not taste like fresh lemon in tea anyway. It is more like a gooey lemon snack cake or something. I liked it for that reason it is more of a desert treat without the guilt. Just use a really small cup as there is only 1.67g in the bag. Not enough for a man mug.
