Hi, my son regularly gets sent some green tea from a friend in japan. it's
very good and much better than anything i have been able to buy in the u.k.

the question is how best to make it. most say to use the water at
temperature 80 c, but i have heard several versions on how best to proceed.
one is just use the leaves once and others have said the first brew pour out
after 20 secs, the second pour out immediately and the third brew let stand
for five minutes.

any advice on what people find is a good way to brew green tea please?
