I would venture to say green tea but I cant pinpoint what type exactly. Someone will come back and drop some knowledge.

Too hard to predict, studies which have looked at the chemical composition of more than one tea have shown that the relative concentrations of those compounds can be altered by many different variables such as growing conditions, processing, freshness, varietal of tea (there's a lot of them) ect...

If you just want to self medicate with caffeine and theanine there's otc pills of both you can take...

Yes and if you just want to get a healthy beverage that will give you some energy, just get some organic green tea - for example a sencha.
Gyokuro is made to be brewed in a concentrated manner, that and Matcha will give you especially much caffeine (theine). But these may be a bit more expensive and special taste than a mass market Sencha.

Still, these have so much more to offer than just two substances. :mrgreen:

Hmm :( but do you know if there is a website that have listed all the content in teas i can read?

i have tried buying theanine in pill form, and it didnt have any effect, strange, maybe it doesnt work if it isnt combined with something else in the tea?

sounds nice, do you have a link that i can read up on the content in these teas? i would like to choose one that has high caffeine and high theanine, and as low catechin as possible, that would be extremely great :shock:

the reason i want the tea to have as Little catechin as possible is because there is contradictory studies made on catechin that it is inhibiting the energy you get from caffeine, so i think its best to have as Little catechin in the tea as possible, because i only want the "calm energy" you get from theanine + caffeine :)

is it by the way generally more caffeine and theanine in black teas? and if so, should black tea grown in shade be of highest caffeine and theanine? i just read on the internet that the reason matcha and goukury has so high caffeine and theanine content and low catechin content is because the shading increaeses these stuff?

and if the theory that tea grown in the shade is better in this case, do you know wich tea has been grown in the shade for the longest time?

If shading is what you want then stick to Japanese greens. kabusencha, gyokuro, matcha, sencha, etc. Gyokuro is probably what you want but prepare to fork out the cash "dude" if you want to drink it everyday. I would suggest getting sencha.

Sencha isn't grown in the shade, and Japanese green teas typically have high catechin levels because steaming preserves them from breakdown.

If you want to see chemical analysis of teas you need to search an academic database for food chemistry articles like this one: http://pubs.acs.org/doi/abs/10.1021/jf010153l which have done a comparison of several varieties of tea.

They didn't look for theanine and the tea with the most caffeine relative to total catechin content was PG Tips with other supermarket black tea blends that they tested being similar.

That article points out a problem though, there's not much research on the exact composition of individual teas being consumed around the world, and even what they tested was a small fraction of what's available in the UK.

There's also this one: http://www.sciencedirect.com/science/ar ... 4002000309 which found similar caffeine and theanine levels for all teas and the lowest catechin in "over-fermented black tea" which I'm not exactly sure what they mean...probably shu pu-erh? "Yunnan tou tea (T32) (Yunnan Province) Yunnan citsebeeng tea (T33) (Yunnan Province)" is what they were labeled as in the groupings list. But there were only 2 teas in that group and making a generalization based on that is a bad idea.

Maybe you see the problem now? Chemical analysis of complex food products like tea is difficult and expensive, so the chemical content of individual teas are not routinely analysed. Broad comparisons of many teas are restricted to only a few representatives for each class because of financial and time limitations, and they're often poorly labeled in the materials and methods sections making comparisons between studies even more difficult.

If you want "calm energy" maybe the thing to do is relax with your tea and take the time to enjoy and appreciate it. Make your tea time a moment of meditation. Most people need time to slow down and relax not more drugs, and tea, of any kind, is really good for this :)

My slightly snarky comment about the pills earlier was because it's much easier to know exactly what ratio of the chemicals you're getting is in that form, but maybe like you noticed when you took theanine tablets there is more to tea than the ratios of a couple of chemicals ;)

OK. Do you know any shade-grown teas that doesnt use the steaming method? What do you think of goukury, tencha and matcha?

Yes i see the problem, i think the only thing to do is try to stick to the theory about shadegrown teas and also the steaming theory, and by that figure out the best tea with trial and error.

Yes true, maybe i can try another brand if its too hard to find the right tea

Either you're unknowingly spelling it wrong or your spellchecker is correcting 'gyokuro' to 'goukury', which is bizzare in itself, but either way I find it quite hilarious!

To the matter at hand, gyokuro, tencha and matcha are all steamed.

I know that but it seems like its probably his best option...

Haha, :) i dont have spellchecking and i didnt know i was Spelling it wrong.

OK, gyokuro, tencha, matcha seemed to have it all :( but the steaming stuff was a real dealbreaker. But if those arent any good, do you know any other teas that is grown as long as possible in the shade and is not steamed?

With regards to Japanese tea, you won't find anything both non-steamed and grown in shade.

Your only other option, I guess, is kamairicha, which is grown in the sun but pan fired instead of steamed.
