A cup of black tea embodies aspects such as appearance, color, aroma, and taste. Appreciating a cup of black tea begins with these four dimensions, combined with personal experience, allowing one to preliminarily savor its flavor. This edition of health preservation through tea drinking has compiled the eight aroma types essential for black tea appreciation.
Hao Xiang (Pekoe Aroma): Characteristic of dry tea made from fresh leaves with white pekoe, tender single buds or one-bud-one-leaf, where golden pekoe is well-revealed through proper processing. Brewing releases a typical pekoe fragrance.
Qing Xiang (Fresh Aroma): A pure, soft, and lasting fragrance. Though not intense, it slowly diffuses, creating a pleasant sensation. This aroma is typical of finely plucked and freshly processed black tea.
Nen Xiang (Tender Aroma): A high, clean, and delicate fragrance, fresh and pleasing to the nose, reminiscent of corn aroma. It comes from tender, soft raw leaves and well-made premium teas.

Huo Xiang (Fire Aroma): Includes rice cake aroma, high-fire aroma, aged-fire aroma, and baked rice crust aroma. Results from older raw materials with more stems, where sufficient heat during drying causes caramelization of sugars in the tea leaves.
Hua Xiang (Floral Aroma): Possesses various aromas similar to natural fresh flowers. A characteristic of some special tea plant varieties after the withering process.
Guo Xiang (Fruity Aroma): Exudes aromas resembling various fruits, such as longan. Some black teas carry an apple-like scent, while Souchong black tea often has a longan aroma (especially the traditional pine-smoke variety).

Tian Xiang (Sweet Aroma): Includes clear sweet fragrance, sweet floral fragrance, jujube fragrance, dried longan fragrance, honey fragrance, etc. A typical aroma of Gongfu black tea made from moderately plucked fresh leaves.
Song Yan Xiang (Pine-Smoke Aroma): Found in teas dried using pine, cypress, maple balls, or yellow vine during processing, such as Souchong black tea.
