Black teas are made from tea leaves that have been quickly and heavily oxidized. This gives the leaf and liquor a dark appearance and significantly changes the aroma and flavor - most notably in the strong body of breakfast teas. Chinese gongfu black teas are less concerned with strength and focus on more subtle characteristics.
Assam teas are grown in the low-lying plains of the Brahmaputra River valley in India, where the warm, tropical climate produces full-bodied, malty, and robust black teas.
