Mydnight, that is a surprise, don't you trust your tastbuds? Or have
you been jaded by the unscrupulous vendors on your travels? A vendor
can tell you that his tea is 10 years or older but from the look of
the tea you can judge roughly its age, or brew it to tell if it worth
that old. Try Hongkong or Macau next time when you get the chance to
go there from China on one of your weekends. You will learn a lot more
there.
