The oolong tea prepared with GSCT10 variety as the raw material showed superb quality, especially the round-leaf Ben Shan. It is characterized by its tightly and rolled leaf with pointed end, bright color similiar to that of banana, with Tie Guanyin aroma and fresh, full and sweet taste, liquor golden yellow in color.
