This tea has an interesting flavor that is a mix of ginseng and oolong tea. It is not bitter but a little sweet with the pungency of the ginseng. Is is a flavor that is hard to describe but good. I added sugar but I think it has some natural sweetness and little of the wood notes common in oolongs. I brewed this with boiling water because I read that you need boiling water because of the ginseng shell around the tea leaves.
