Congou \Con"gou\, Congo \Con"go\, n. [Chin. kung-foo labor.]
   Black tea, of higher grade (finer leaf and less dusty) than
   the present bohea. See {Tea}.

         Of black teas, the great mass is called Congou, or the
         ``well worked'', a name which took the place of the
         Bohea of 150 years ago, and is now itself giving way to
         the term ``English breakfast tea.''      --S. W.
                                                  Williams.
