Most of what I have read says there is roughly 35 mg caffeine in a
"cup" of green tea. So I am wondering if this number applies to a
serving of the leaf or is it applied to one of the 5 or so "cups" you
can get from a serving of that leaf? I can't believe there is 35 mg
of caffiene multiplied by 5 cups in one teaspoon of leaf. We all know
that most of the caffiene comes out early in the steeping, and the
rest of the stuff (amino acids, polyphenols etc..) comes out in later
steeps, but I am wondering about the total amounts. When I drink
green I get many steeps, usually at least 5, while black tea gives me
two steeps at best.

Ah-ha. So you think mabey they are steeping green tea for 5 min. in
boiling water in the lab? That could be, that way they are treating
all teas the same way (I still can't imagine a japanese scientist for
example pouring boiling water on some sencha and letting it sit there
for five min. seems a little funny even in the lab)
I don't think I have read anything that talked about the difference
in steeping temperature with regard to caffiene. What have you heard
about this?
