Steeping Times AFTER refrigerating Japanese green tea leaves?

[beforewisdom]

A few months ago I drove up to a Japanese tea house and had a small pot of gyokuro. The owner was disturbed that I only wanted one steeping. I explained to her that I had a limited tolerance for caffeine and it was late in the day.

She insisted that I take the leaves home in a paper cup, refrigerate them, and use them again the next day --- but with a far longer steeping.

It worked. Those leaves made a very nice small pot of gyokuro the next day.

Fast forward, I am now working my way through a tin of Rishi sencha.

The directions call for about 4.8 grams of leaves. I love the strong grassy taste, but I've found that "I've had too much" with my usual habit of trying to get 3 steeping out of each serving of leaves.

I would like to try cutting down to 1 steeping at this dose, and refrigerating the leaves overnight.

The directions on the tin call for a 2 min brew on the first steeping and then 1 min afterwards.

After a night in the fridge would I start over with a 2min brew or go longer?

Thanks for any clues.

Did you know that most of the caffeine comes out in the first few seconds of steeping?

Yes, I have read that before. Nonetheless, when I drink more re-steepings in a single day I still feel overstimulated than when I don't.

Probably because the decaf after a few seconds is nothing but a hopeful myth. http://chadao.blogspot.com/2008/02/caff ... ality.html. For instance in one study only 9% of the caffeine out in 30seconds('Tea preparation and its influence on methylxanthine concentration,' appeared in Food Research International Vol 29, Nos 3-4, pp. 325-330.)

Edit:
As for the original question, no idea really. My first guess would actually be shorter as they're not dry when you stick them in the fridge and as such the leaves have been steeping somewhat all night.

Thank you for the info, pizzapotomus.
OP: can you brew 1.6g in one third the water for all the steeps?

1/3 of a cup is not a lot of tea to drink

You'd do 3 infusions. 3x1.6g=4.8g.

A lot/a little is all relative, I was drinking from a 2oz cup earlier today If you don't like the idea of 3 small servings though you could always brew them in quick succession and combine them in one glass. One "averaged" cup is a different experience than 3 distinct infusions but then again so is the refrigeration.

Another idea inspired by the fact that our temperatures have just jumped into the 80s this week, you could reuse the leafs for a cold brew, stick the used leaves in the fridge with water for chilled tea. That's only 2 infusions but at least for me a cold brew can be very nice now and then.
