Black tea, one of the world's most beloved beverages, captivates drinkers with its rich aroma and naturally sweet flavor. This comprehensive guide explores black tea's origins, production process, regional varieties, and remarkable health benefits.
The Origins of Black Tea
The earliest black tea originated from Tongmu Village's Lapsang Souchong, initially called "dark tea" due to its blackened leaves. Notably:
- Qimen Gongfu Black Tea was first named "Qimen Oolong" for its dark-brown appearance
- Overseas markets later coined the term "Black Tea" referencing the leaf color
- Modern classification systems categorize these as Souchong and Keemun black teas based on processing methods
Black Tea Production Process
As a fully fermented tea, black tea undergoes deeper oxidation than green, white, or yellow teas, resulting in its characteristic:
- Ruby-red liquor
- Robust, malty flavor profile
- Higher caffeine content (30-60mg per cup)
Key Production Steps:
- Withering: Fresh leaves lose 30-40% moisture
- Rolling/Cutting: Breaks cell walls to initiate oxidation
- Fermentation: Enzymatic oxidation (2-4 hours at 22-26°C)
- Drying: Halts fermentation at optimal point
- Refining: Sorting, grading, and blending for consistency
Traditional Lapsang Souchong adds unique wok-roasting and pinewood smoking stages.
