In addition to Space's experience and Fukamushi Dynasty's, I too find that white tea is loaded with caffeine. And, quite frankly, I find it a little annoying when people are so adamant that white tea is low in caffeine, as if you repeat this notion enough it will then become reality.
Silver needle is the example I'm using, because that is the white tea I had in which the caffeine effect was so obvious. So, my personal conclusion is that at the very least silver needle is not a low caffeinated beverage and that any notion that it is is merely misinformation.
Could other white tea's, like peony be low in caffeine... They *could* but I'm not convinced of it, and the silver needle, from my experience gives every indication of high levels of caffeine.

White tea will get me more jazzed then three bowls of koicha, so I've always doubted the claims that white tea has such a low amount of caffiene.
Perhaps I just react to it differently...
