Interesting I had no idea tannin had that affect. That may also explain the effects after red wine drinking. Thank you. However, speaking of white tea (and really most herbal tea), my understanding is that it does not contain tannin, and very low levels of caffeine (none when speaking of most herbal). If I wanted a caffeine high I would drink something else. So with white tea, I agree it's a matter of taste, but other than that, would you think steeping time matters?
