Tea maniac here o/
I've got myself a transparent teapot, just for flowering teas =) BTW, a trick I learned from anime, green and white teas are better if you don't pour them straight into boiling water. Use water about 80C and leave them to infuse for 2 ~ 3 minutes.
If the white / green tea tastes bitter, it's because you burnt it.
Ps. he anime mentioned above was "Oh my goddess". Although it may have been the manga rather than the anime and I'm mixing things up.
