The naming of teas is a difficult matter, It isn't just one of your everyday games-
Some might think you as mad as a hatter
Should you tell them each goes by several names.
For starts each tea in this world must belong
To the families Black or Green or Oolong;
Then look more closely at these family trees-
Some include Indians along with Chinese. ~ T.S. Elliot, "The Naming of Cats"
