  Ah that would make sense. And water temperature likely plays a vital role as well. But for properly brewed green tea, it will still result in less caffeine than red tea as expected.

  I think it's some of both. I emulate my dealer (Taiwanese direct importer), who intimated that she skips the strainer with her green tea and just puts here whole leaf green tea straight into the cup (you can only do this with whole leaf, as your lip becomes the strainer and broken tea ends up in your teeth). She reuses the same cup all day, topping it off when it's half full. When I space and drain it (often in the middle of a coding session), it still tastes and acts like tea for at least the first three cups, after that it gets pretty weak, until I abandon it for a good long while and then discover it's gone from weak to bitter.
