OK... I got inspired to try cold brewing last night. I collect old Pyrex glass decanters from the 50's... very pretty for tea, btw, will have to photograph and post... so anyway, I put gyokuro leaf and cold water in a decanter and refrigerated overnight.
I was surprised at how cloudy it looked, and how there was minimal fragrance... I was really afraid it was going to taste like cold dishwater.
I'm drinking now, and it's quite mild. I think maybe I needed to use a bit more leaf, but I have to say... this is the best green tea I have succeeded in brewing so far. Zero bitterness, great clear flavor, no grassy anything... and I actually really like it cold... I'd only been trying it hot before, other than the flavored for iced tea.
Anyway, thought I would share.

Personally, I don't like to leave Japanese Greens out overnight because of oxidation.
This is how I prefer to cold brew:

Sounds good but at room temperature - it may take 3-4 hours for the ice to melt.trent wrote:Personally, I don't like to leave Japanese Greens out overnight because of oxidation.

ALSO - and this is very important - ice itself will may contribute an unpleasent taste to the tea. Melted ice-water tastes terrible without any tea.
I have tried this and I love it, will do it again once I open my next lot of Gyokuro. I usually use about 8-9g of leaf with about 7 or 8 good sized ice cubes and leave it in my pot for about 4-5 hours. I have also tried putting the pot in the fridge for overnight brewing and this I find works even better... a lovely smooth vegetal brew. 

Ok - just tried it. Could not wait for 4-5 hours so I just drank it up after ~ 2 hrs. Now as I suspected - the ice does affect the taste. The key is - may be - if we brew the tea with already ice cold bottled water? If temperature is the issue - we can keep the pot in the refridgerator.
Would be now be classified as gyokuro nuts?
In any case - I hope someone who knows what this umami taste is - can brew with ice cold water.
