White and yellow teas are among the most subtle.

I find that white tea is good with fruity flavors. Since the tea itself is so subtle, they have room to zazz up!

I haven't a clue, but I do wonder if theanine is any 'stronger' in brewed white teas than in other teas. I wish I had access to a multi-million dollar lab. :(

Everything you need to know about caffeine in tea: http://www.teageek.net/blog/2008/01/caf ... -your-cup/

Also I'm pretty sure I've seen a study that suggests white tea has, on average, the most caffeine of the categories. I'll look for it.

I find that white tea has a very tonic effect on me and that it can easily keep me awake at night... :wink:

This classic article goes into different factors, and does a sequence of measurements related to caffeine extraction rates that comes as close to settling all that as one test session could:

I wrote two blogs posts on the subject of caffeine, the first more on dosage amounts, dependency, and withdrawal issues, and the second more on amounts of caffeine in different tea types, which also works as simplified version of some of the first:

I have recently read that young tea buds which are commonly found in white teas such as Silver Needle and White Peony contain a relatively high level of caffeine.
HOWEVER, they also have much higher L-theanine content, which balances out the caffeine, putting you into an alert and yet calm state.
Also, as a few other members have mentioned in this thread - the longer the steeping time and the higher the temperature, the more caffeine will get dissolved in your cup...

I've looked into this before, and my conclusion is that with all those interacting factors, it's almost impossible to make any generalized statements about caffeine content in any tea. Any significant change in any of the important factors will completely change how much caffeine is extracted.

I didn't buy it yet. But if this one good enough and healthy will surely give a try for it.

Tea type is just one of the many factor that determines caffeine levels. Buds contain more caffeine, but at the same time they're steeped at much lower temperatures resulting in less caffeine extraction. I think in practice, it's just so hard to come up with rule of thumbs on caffeine levels.
