I once read about a japanese method for green tea. The first cup is for the enemy, brewed with boiling water for a few seconds to pull out the bitterness and discarded. The second is for a good friend and the third is for you.

My brother once told me, that a japanese professor measured how much of the healthy substances gets drawn out at all temperatures. He found 60°C to be optimal.

I used 80°C for 2nd & 3rd brewing though, since i really dislike the taste at 70°C and lower.
