How much caffeine is in green tea?

[vhines200]

I'm confused, some people say a lot, other say just a little.

Per Serving -<br />
Coffee　40mg<br />
Green Tea　　　150mg<br />
Black Tea　　　50～60mg<br />
Coke　40～60mg<br />
Cocoa　　10～20mg<br />
<br />
But - as you may know, there are a lot of different kinds of green tea, and the caffeine content differs by tea leaf type, as well as drying method. So tea from roasted rice, is of lesser caffeine content than coffee.<br />
<br />
Also - caffeine in green tea is supposedly a better caffeine than the one in coffee. <br />
