High Mountain Oolong: Alishan, Lishan, Shan Lin Xi and Da Yu Ling Compared
High mountain oolong (gao shan cha, 高山茶) is Taiwanese oolong grown above roughly 1,000 metres in the island's central mountains. Cool nights, mist and slow growth give thick, sweet leaves; light oxidation and minimal roasting keep them floral and creamy. The best-known names are Alishan, Shan Lin Xi, Lishan and Da Yu Ling, roughly in order of rising altitude and prestige. They taste of lilac, orchid, fresh cream, pear and green fruit, with a thick, silky texture and a cooling finish. Brew at 80–90 °C, and keep the tea airtight and cool: it's best within a year.
My first high mountain oolong was a Lishan a friend brought back from Taiwan, and I've told that story in my Taiwanese oolong guide. What I didn't say there is how long it took me to taste the differences between the mountains. For a couple of years they all tasted like "nice floral Taiwanese oolong" to me. What finally taught me was buying four at once, from one seller and one season, and brewing them side by side. Suddenly Alishan was soft and buttery, Shan Lin Xi was greener and brighter, Lishan was sweet and fruity, and Da Yu Ling was so clean and cooling it almost felt like mountain air. More in the oolong guide.
The main mountains#
| Mountain | Typical altitude | Character |
|---|---|---|
| Alishan (阿里山) | Around 1,000–1,500 m | Soft, creamy, buttery, gentle florals; the most widely available |
| Shan Lin Xi (杉林溪) | Around 1,500–1,800 m | Brighter and greener, fresh bamboo and pine forest notes |
| Lishan (梨山) | Around 1,800–2,200 m | Sweet, fruity (pear, stone fruit), thick and cooling |
| Da Yu Ling (大禹嶺) | Around 2,000–2,600 m | The cleanest and most cooling, very long sweet finish; very scarce |
Altitudes are approximate; each name covers a range of gardens. Treat big names with caution: "Lishan" and "Da Yu Ling" are often used for tea from lower or neighbouring areas. A seller who names the garden and harvest is worth more than any mountain on the label.
How it's made#
High mountain oolong is picked from bushes (most often the Qing Xin oolong cultivar) in spring and winter, and sometimes in summer and autumn. The leaves are withered, shaken to bruise the edges, lightly oxidized, fixed, and then rolled into tight balls through many rounds of wrapping and kneading in cloth. Most get only a light finishing roast, which keeps them green and floral. That's what makes them fragile: freshness is everything.
Spring vs winter#
| Harvest | Character |
|---|---|
| Spring | Fuller, richer, more body; many consider it the best |
| Winter | Lighter, very fragrant and sweet, more floral |
| Summer/autumn | Usually lighter and less prized for gao shan cha |
How to brew high mountain oolong#
| Leaf / 100 ml | Water | Rinse | 1st steep | Then | Steeps |
|---|---|---|---|---|---|
| 6 g | 80–90 °C | Quick | 10 s (balls need to open) | +5 s | 6–8 |
- The first steep is often light; judge the tea from the third.
- A porcelain gaiwan shows the aroma best. The leaves expand enormously, so don't overfill.
- It's also one of the best teas for cold brew: see cold brew tea.

My side-by-side: four mountains#
Four 100 ml gaiwans, 5 g each, all spring harvest from one seller, 95 °C, one quick rinse.
Steep 1 (20 s). Alishan: buttery, lilac. Shan Lin Xi: greener, fresh bamboo. Lishan: sweet pear. Da Yu Ling: very clean, a cool, almost minty sweetness.
Steep 3 (20 s). Alishan: creamy and soft. Shan Lin Xi: brighter, a pine note. Lishan: thick, fruity. Da Yu Ling: thickest of all, long cooling finish.
Steep 7 (60 s). Alishan and Shan Lin Xi were getting thin. Lishan and Da Yu Ling were still sweet and full.
That pattern repeats every time I do this: higher tea lasts longer and finishes cleaner.
How to store it#
This is one of the most fragile oolongs. Keep it airtight, dark and cool, ideally in its original vacuum pack until you open it. In Taiwan and southern Fujian, light oolongs that need to keep longer than a couple of months are stored vacuum-packed and chilled. If you use the fridge, split it into small sealed portions and let each portion reach room temperature before opening, so no condensation forms. Drink it within about a year.
Myths about high mountain oolong#
"Higher is always better." Higher usually means cleaner and sweeter, but a well-made Alishan beats a poorly made "Lishan".
"It's a kind of green tea." It's a lightly oxidized oolong, shaken and rolled, not a green tea.
"The mountain name guarantees the origin." Mislabelled origin is common, especially for Lishan and Da Yu Ling.
My honest take#
Buy an Alishan and a Lishan from the same seller and season, and brew them side by side. Within three steeps you'll understand what altitude does, and whether the higher price of the higher mountains is worth it to you.
The bottom line#
Taiwanese high mountain oolong is floral, creamy and sweet, and it gets cleaner and more cooling as the altitude rises from Alishan to Da Yu Ling. Brew at 80–90 °C, judge from the third steep, and store it airtight and cool. For the roasted side of Taiwan, see Dong Ding.
