Tea contains tannin as well as caffeine, the tannin is a relaxant the caffeine a stimulant, the caffeine comes out first. According to fmltea[1] the caffeine will all be drawn out in the 1st 2mins and the tannin in 5mins. I have previously heard that the greatest caffeine hit is obtained by leaving the teabag in for 30 seconds, I imagine it will depend greatly on the type of tea and how you brew it. It does however tell you that with tea unlike coffee, stronger flavor does not mean stronger caffeine.

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?
