For the best quality Green or Oolong tea try King's tea range from Ten
ren. Know as Cha wong, true tea connoisseurs in the far east swear by
it. Its the most recongised brand in the Far East. Once you try this,
anything else is going to be second best. Its very hard to get hold and
quite expensive but if you really appriciate quality then its well
worth it. I get mine from http://www.exotictea.co.uk, and they deliver
to europe. Put it to the test, you will not be disappointed.
