Dear AnnaStrophic: I am reading Smithsonian magazine for Dec. 2001. An article about paleontologists finding whale skeletons in Andes Mountains of Chile mentions their being served "green tea - maté".
I found a URL about it:

Since it is a product of Brazil, I thought you might be able to tell us about it. It sounds good, but does it taste good? And can it be bought in U.S.?
