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.
Smoked teas, such as Lapsang Souchong, are traditionally made by drying tea leaves over smoldering wood fires. This imparts the tea with its distinctive smoky aroma and rich, campfire-like flavor.
