The subject will terrify most of you I suggest only cold tea
drinkers participate in this thread.

How do you prepare your iced green tea? The way I do it is, I would
boil 1 liter of water and cool it down to 170F. I'd then throw in 33g
of looseleaf sencha in it and time it exactly for 3 minutes and then
transfer them to a pitcher while straining the leaves. I'd leave it
out for 15 minutes, for it to cool down and then mix in 1 liter of ice
cold water. I would then leave it in the fridge and drink it all day
long. It's refreshing. This batch is 2 liters. You could add a leaf
of mint in your glass before you drink it. Just enough to taste the
mint but not overwhelm the tea. I think this batch equals 10 servings.
That may sound like a lot of caffeine, but it isn't. I get a wired up
with just one cup of coffee but drinking this entire 2 liter batch
doesn't do a thing to me. When I say 3 minutes, I mean exactly 3
minutes. Your batch should be transfered, strained, and seperated from
the leaves in exactly 3 minutes. The temperature has to be exactly
170F. Another thing, don't add ice! When ice melts, it dilutes the
tea. The top half of the glass will taste watery. Use a frozen beer
mug instead.

I've tried bancha with my method above and it's nasty. Gunpowder tea
is somewhat tolerable. For me, Sencha is the only way if you want it
iced cold. I've tried those imported bottled green tea but it just
isn't the same because they have sugar in it. Sugar just mask the
taste of the tea. The aroma and the essence of the bottled ones seems
absent, making the tea taste flat.

Drinking it cold, I could taste the characteristics of Sencha. The
aroma, that distinct taste as it spread across my taste buds.
Sometimes when I'm thirsty and on my way home from work, I'd hold off
buying any sodas. All I crave for is to get my 16 oz frozen beer mug
from my freezer, pour my iced green tea, take my shoes and socks off,
and just drink. ahhhhh
