If you are looking 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.
