Wu Long vs. Oolong: The Transliteration Explained
The fundamental fact is that Wu Long and oolong refer to the exact same category of tea. The discrepancy in the name comes from two different systems used to romanize Chinese characters. 'Wu Long' follows the modern pinyin system, while 'oolong' is an older, more established English transliteration. Both are derived from the Chinese term '烏龍' (wūlóng), which translates to 'black dragon'.
The name 'black dragon' is said to originate from the dark, twisted appearance of some oolong tea leaves. For those new to the world of tea, stumbling upon these two different names can be confusing, but it's an important detail to grasp to fully appreciate the world of semi-oxidized teas. Whether you see 'oolong' on a menu or 'Wu Long' on a package, you can be sure you are drinking the same type of tea.
A Spectrum of Flavor: The Semi-Oxidation Process
What truly defines oolong tea is its partial oxidation, a meticulous process that places it between unoxidized green tea and fully oxidized black tea. The level of oxidation can vary significantly, ranging from 10% to 70% or higher, and is carefully controlled by a skilled tea master. This variable oxidation is what gives oolong its famously diverse range of flavors and aromas. The process is a work of art, involving several stages:
- Plucking: The tea leaves are carefully selected, often including a bud and a few leaves.
- Withering: Leaves are spread out to wilt, allowing moisture to evaporate and making them more pliable.
- Bruising (Shaking): The leaves are gently bruised or shaken in baskets, which breaks down the cell walls and initiates oxidation.
- Fixing (Kill-Green): The oxidation is stopped at the desired point by applying heat, typically through pan-firing or steaming.
- Rolling/Shaping: Leaves are rolled or twisted into various shapes, from long, twisted leaves to tightly-rolled pellets or 'pearls'.
- Drying/Roasting: The final step involves drying and, for some varieties, roasting to develop deeper, richer flavors.
This complex craftsmanship is why oolong teas offer such a wide range of tastes, from light and floral to dark, roasted, and honey-like.
Diverse Regional Styles and Notable Varieties
The most prominent oolong tea-producing regions are China, particularly the Fujian and Guangdong provinces, and Taiwan. Each region, and even sub-region, has developed its own unique styles and processing methods, leading to a vibrant array of flavors.
Here are some of the most well-known types of oolong:
- Tieguanyin (Iron Goddess of Mercy): Originating from the Anxi county of Fujian, this tea is one of the most famous oolongs, known for its light, green, and floral profile.
- Da Hong Pao (Big Red Robe): A dark, rock oolong from the Wuyi Mountains of Fujian, celebrated for its complex, mineral, and roasted notes.
- Dan Cong (Phoenix Single Bush): From the Phoenix Mountains of Guangdong, these are known for their incredibly aromatic, fruity, and fragrant profiles, with each 'single bush' having its own unique character.
- Dong Ding (Frozen Peak): A Taiwanese oolong, known for its smooth, roasted, and sweet finish.
- Oriental Beauty (Bai Hao): A Taiwanese oolong that is more heavily oxidized and known for its honeyed and fruity flavor.
Comparison: Wu Long Tea vs. Other Teas
To better understand what makes Wu Long (oolong) tea special, it's helpful to compare it to other types of tea derived from the Camellia sinensis plant.
| Feature | Wu Long (Oolong) Tea | Green Tea | Black Tea | White Tea |
|---|---|---|---|---|
| Oxidation Level | Partial (10-70%) | None (0%) | Full (100%) | Minimal (0-5%) |
| Flavor Profile | Extremely diverse, from floral and sweet to roasted and nutty. | Fresh, grassy, and vegetal. | Bold, malty, and robust. | Delicate, subtle, and floral |
| Processing | Complex and lengthy, withering, bruising, fixing, and shaping. | Brief, involves steaming or pan-firing to halt oxidation. | Rolled and fully oxidized before drying. | Least processed; withered and dried. |
| Caffeine Level | Medium, varies by oxidation and processing. | Low to medium. | High. | Low. |
Brewing Your Wu Long Tea
Enjoying a cup of Wu Long tea is a simple pleasure, but the brewing process can greatly influence the final flavor. The traditional method is Gongfu Cha, which uses a small teapot and multiple short infusions to draw out the tea's nuanced characteristics. However, a western-style brew is also very effective.
Western Brewing Method
- Gather your equipment: You will need loose leaf tea, a teapot or infuser, and filtered water.
- Heat water: Heat water to just below boiling. For lightly oxidized oolongs, use about 185°F (85°C); for darker oolongs, use up to 212°F (100°C).
- Use correct ratio: Add one teaspoon of oolong leaves per 8 ounces of water.
- Steep: Steep for 1 to 5 minutes, adjusting for your preferred strength. Lighter oolongs typically need shorter steep times.
- Re-infuse: Oolong leaves can be re-steeped multiple times, with each infusion revealing new layers of flavor.
Conclusion
In short, there is no difference between Wu Long tea and oolong tea. The former is a modern pinyin spelling, while the latter is a traditional English transliteration of the Chinese term for 'black dragon' tea. Understanding this distinction is the first step towards exploring the incredibly complex and rewarding world of semi-oxidized teas. From the high mountains of Taiwan to the ancient tea regions of Fujian, oolong offers a vast spectrum of flavors and aromas waiting to be discovered, making it a favorite among tea enthusiasts worldwide.
