In China you see the local peoples carrying a jar or drinking bottle filled
with green tea leaves and water. They make the tea with boiling water in
the morning and drink the whole day from the bottle, leaving the tea leaves
in it.
I have brought some green tea from china and I’m drinking it the way the
locals do. I like this very much but I’m running out of tea leaves and can’t
remember the name of the tea (I think it’s longjing).

Now I would like to ask which teas I can use for it and won’t become bitter
when you leave the leaves in the bottle?
Thanks in advance
