Ok, I tried this again, and it came out ENTIRELY different.
First, I did the Shinobicha method, of Ice-brewing the tea—go here if you want to know more: http://74.125.155.132/search?q=cache:agAyOfC0rPgJ:www.mellowmonk.com/2009/08/gongfu-girl-makes-mellow-monk.html+shinobicha&cd=3&hl=de&ct=clnk&gl=us
It tasted wonderful and refreshing and much better than the other attempts.
Then I steeped it a 2nd time in 160 degree water, for just a few seconds and poured again…this time the flavor was as I had originally expected it to be, full, ‘vegetal’, umami…Mmmmm
So I’m putting this one higher up…80
