Taiwanese Oolong Tea
Share
Taiwanese Oolong Tea is renowned worldwide for its unique flavors, craftsmanship, and diverse varieties. Taiwan’s mountainous terrain, favorable climate, and tea-making traditions make it one of the leading producers of high-quality oolong teas. Oolong tea is a semi-oxidized tea that falls between green and black tea in terms of oxidation levels, offering a wide range of aromas and flavors, from floral and light to rich and roasted.
Key Characteristics of Taiwanese Oolong Tea:
- Flavor Profile: Varies from sweet and floral to rich and creamy with fruity or nutty notes.
- Oxidation Level: Ranges from 10% to 80%, depending on the style.
- Aroma: Often highly aromatic, with notes of orchids, lilacs, or tropical fruits.
- Appearance: Rolled into tight, ball-like shapes or twisted, long leaves, depending on the variety.
Major Varieties of Taiwanese Oolong Tea:
- Origin: Named after Dong Ding Mountain in Nantou County.
- Flavor: Medium oxidation and roast, with a rich, toasty flavor and sweet, floral aftertaste. Dong Ding Oolong is one of Taiwan’s most famous oolong teas and is traditionally charcoal-roasted.
- Aroma: Notes of honey, flowers, and baked fruit.
2. Ali Shan Oolong (阿里山乌龙):
- Origin: Grown in the Ali Shan (Alishan) Mountain range, typically at elevations above 1,000 meters.
- Flavor: Lightly oxidized, this tea has a smooth, creamy texture with a sweet, floral flavor. It’s known for its “gao shan” (高山) or high-mountain qualities, which bring out delicate, refreshing notes.
- Aroma: Orchid, jasmine, and other floral scents.
- Origin: From Lishan Mountain, one of the highest tea-growing areas in Taiwan.
- Flavor: Light to medium oxidation, with a more pronounced fruity and floral profile. Lishan Oolong is prized for its high-altitude growing conditions, which contribute to a rich, sweet, and complex flavor.
- Aroma: Fruity (pear, peach) and floral, with a buttery mouthfeel.
4. Baozhong (Pouchong) Tea (包种茶):
- Origin: Primarily grown in Wenshan near Taipei.
- Flavor: This lightly oxidized oolong is closer to green tea in character, with a fresh, grassy, and slightly floral flavor. Baozhong teas are known for their delicate processing and minimal oxidation (about 10–20%).
- Aroma: Orchid or jasmine, with a light, fresh fragrance.
5. Oriental Beauty (东方美人茶):
- Origin: Also known as Bai Hao Oolong or White-Tipped Oolong, this tea is famous in Hsinchu County.
- Flavor: High-oxidation (around 60-70%) oolong with a natural sweetness and honey-like flavor. The tea leaves are harvested after being bitten by tea green leafhoppers, which trigger a chemical reaction in the leaves, enhancing the tea’s sweetness and complexity.
- Aroma: Honey, peach, and floral notes.
6. Shan Lin Xi Oolong (杉林溪乌龙):
- Origin: Grown in the Shan Lin Xi area, at altitudes of 1,500–1,900 meters.
- Flavor: Light to medium oxidation, with a creamy, buttery texture and complex floral and fruity notes. The high altitude of Shan Lin Xi contributes to a refreshing, clean taste.
- Aroma: Floral, with hints of cream or milk.
Production Process of Taiwanese Oolong Tea:
1. Plucking:
- Tea leaves are hand-picked, usually selecting the bud and top 2–3 leaves. The altitude at which the leaves are grown contributes significantly to the quality, as cooler temperatures slow down leaf growth, concentrating flavors.
2. Withering:
- Freshly harvested leaves are spread out to wither under the sun or indoors to lose moisture. This step helps soften the leaves and prepare them for oxidation.
3. Tossing and Oxidation:
- The leaves are gently shaken or tossed to bruise the edges, which initiates oxidation. This is a critical step in determining the flavor profile, with more tossing leading to higher oxidation levels. During this process, the tea develops its signature flavors, from light and floral to darker, roasted notes.
4. Fixation:
- The oxidation process is halted by heating the leaves in a process called “kill-green” (杀青), which preserves the flavor and locks in the aroma. This step stops the enzymatic reactions in the leaves.
5. Rolling:
- The leaves are rolled into their final shape, whether tightly rolled balls or twisted strands. Rolling helps release the juices and essential oils, intensifying the flavor.
6. Roasting:
- Many oolong teas, especially those with higher oxidation levels, are roasted to develop a more complex flavor. This step may be repeated several times over a charcoal fire or electric heat, depending on the tea’s style.
7. Final Drying and Sorting:
- The tea is dried to remove any remaining moisture and ensure the leaves are ready for storage and aging. After drying, the leaves are sorted by size and quality before packaging.
The Impact of Terroir on Taiwanese Oolong Tea:
- Taiwan’s diverse landscapes, from lowland plains to high mountain ranges, play a significant role in shaping the unique characteristics of its oolong teas. High-mountain oolongs are especially prized for their clarity, freshness, and distinct “yun” (韵), or lingering aftertaste, which is influenced by the cool, misty environments where the tea is grown.
- The higher the elevation, the slower the tea plants grow, allowing them to absorb more nutrients, resulting in teas with a richer, more nuanced flavor profile.
Taiwanese Tea Culture:
- Tea is deeply rooted in Taiwanese culture, with tea houses, tea competitions, and festivals dedicated to the art of oolong tea production and appreciation. Taiwan’s government has also played a role in promoting and preserving the quality of its tea by establishing grading systems and supporting traditional farming practices.
- Taiwanese people often drink tea during social gatherings, business meetings, and family occasions, and tea ceremonies emphasize the appreciation of aroma, taste, and the beauty of tea leaves as they unfurl during brewing.
Taiwanese oolong tea is a product of centuries of tea-making expertise combined with the island’s unique climate and geography. Its diversity in flavor, from light and floral to deep and roasted, makes it one of the most respected and sought-after oolongs globally. Taiwanese oolongs offer a rich sensory experience and embody the artistry and tradition that have been passed down through generations of tea farmers.
