The "Crane Label" is the main product line for Xiaguan Products from the mid-90's until 2007.  The ripe tea produced under this label is typically more refined than the ripe tea sold under the "Bao Yan" (Tibetan/Holy Flame) label.  After having aged for 5 years the newish "wo dui" flavor is completely gone.  This is a very pleasant ripe tea.
