This gunpowder green tea is also know as "Zucha" or "Pearl Tea".  It is a much finer version than standard gunpowder tea.  The temple of heaven features a very tightly rolled ball.  This is a sign of the high quality this tea offers.  The aroma is softer and less biter than the standard gunpowder version. 
Try pouring away the first brew and the second will eliminate most of the caffeine.
