Quick tip: steep tea for 30 seconds and then discard that water and steep again for 30 seconds longer. 99% of the caffeine will drop in that first steeping.

Do you have any source on this? I've heard a number of claims about the effects of tea preparation on caffeine content, but very little evidence.

I was taught this at an industry conference on tea but I just did a Google search and it looks like recent research shows this to be false. Sorry for spreading bad info!

I do this with black tea and it always seemed effective, but maybe it was the placebo effect all along.
