How is jin jun mei (a Chinese tea) made? I'd like to know whether jin jun mei (golden beautiful eyebrow, a Chinese tea) is kosher. To know that, I first need to know its ingredients and how it's processed.  

What are the ingredients in Jin Jun Mei?
How are the ingredients processed?
According to Wikipedia, Jin Jun Mei tea is just a (unsmoked) Lapsang souchong tea or, in simpler words, a black tea. It is considered a black tea of special or extra high quality, but there are no indications that it is produced differently that "normal" black teas.

You might double-check with your religious authorities as the question of being kosher or not is off-topic here, but as I see it, the same rules apply as for any black tea.
