Definition:
Alishan (阿里山) is a mountain range and national scenic area in Chiayi County, central Taiwan, and one of the island’s premier tea-growing regions. Alishan tea — typically a lightly to medium oxidised, ball-rolled oolong — is one of the most recognised names in Taiwanese specialty tea, prized for the flavour qualities that emerge from its high-altitude growing conditions.
Geography
- Location: Central Taiwan, Chiayi County
- Elevation: Tea gardens sit between approximately 1,000–1,800 metres above sea level (some high gardens approaching 2,000m)
- Climate: Cool temperatures, frequent cloud cover and mist, significant day-night temperature variation (diurnal range)
- Rainfall: High annual rainfall, with mist and cloud providing additional moisture
Why High Altitude Matters for Tea
High-altitude growing conditions in Alishan produce tea leaves with distinct characteristics:
- Slower growth: Cool temperatures slow the growth rate, concentrating flavour compounds in the leaf
- Lower pest pressure at altitude: Reduces need for pesticides
- Mist and cloud cover: Reduces intense sunlight, which increases amino acid concentration (particularly theanine) relative to catechin content — leading to lower astringency and more umami or sweet character
- Larger diurnal temperature range: Cool nights slow the breakdown of aroma compounds
Alishan Tea Character
- Aroma: Prominent floral (orchid, gardenia, osmanthus), often with a creamy or milky note
- Taste: Smooth, low astringency, creamy body, lingering sweet finish
- Liquor: Pale gold to golden green
- Texture: Notable creaminess — often the first attribute tea drinkers notice
Key Growing Areas within Alishan
Several villages and sub-regions within the Alishan area are known for tea:
| Area/Village | Chinesee | Notes |
|---|---|---|
| Ruitai | 瑞太 | Lower elevation Alishan tea |
| Shizhuo | 石棹 | Mid-elevation; well-regarded |
| Zhuqi | 竹崎 | Border of the defined region |
| Fenqihu | 奮起湖 | Lower; historical rail junction area |
The most highly valued Alishan teas typically come from the higher elevations — 1,400m and above — from gardens near the main Alishan forest railway’s upper stations.
Cultivars Grown
Primarily:
- Qingxin Oolong — the dominant cultivar, also called Ruanzhi
- Cuiyu Oolong — Jade oolong, sometimes blended with Qingxin
- Jinxuan (Milk Oolong / TRES No. 12) — creamy, buttery aroma

| Lishan | 2,000–2,600m | More complex; higher elevation expression |
| Shanlinxi | 1,400–1,800m | Deeper body; slightly more oxidised |
| Dayuling | 2,400–2,700m | Highest; the most prized and expensive |
