Amount of Caffeine in Teas?

Postby caradrake » Feb 9th, '08, 10:40

Blame padre if this is the wrong place.

I'm curious how much caffeine is in a 4 oz cup of miyabi, or a cup of jasmine tea, compared to the same amount of soda. Does anyone have any ideas?

Here is some info:
http://www.energyfiend.com/the-caffeine-database/

[Mary's Edit: According to that list, tea (brewed) has 5.88 mg/oz, tea (green) has 3.13 mg/oz, and Coca-Cola Classic has 2.88 mg/oz. A can of coke has 12 oz, which would be more caffeine per serving than the 4 oz tea.]

Sencha doesn't have much caffeine.

Either that, or you drink so much of it you're immune to it's effects! I get a little hoppin' from sencha, but it's that tranquil zen focus sort of alertness. I think Chip's the one who said "you could watch paint dry" with it. It's like that...you've got the alertness to notice stuff, but the calm and the focus to be interested by it for a sustained period of time...

Or I'm just nuts. Whatev.

888 -- White tea is definitely the most stimulating one for me. Even after being heralded as being lowest in caffeine. Throw some ungtss on that one.

Well, the leaf buds *do* have the highest amount of caffeine in 'em compared to the other plant bits...not sure how it translates in the cup though.

I read somewhere that the caffeine in green and white tea is more biologically active than that in the oxidized teas. Who knows...

Try Karigane or kukicha, a nice lower caffeine Japanese green. The roasted ones have even less they say.

In case anyone is interested in the "decaffeinating by throwing away the first steep" myth (sorry tenuki, I wanted to respond in the TeaDay thread, but it is now locked), please note that they are talking about 5 minute long steeps. I refer you to this article posted about the same study (and another study).

I have heard that it is about 1/4 of that in a cup of coffee.
