Gaoshan Oolong: Analyzing 1,583 teas from 98 sellers

Gaoshan oolong (high-mountain oolong) is Taiwanese oolong grown at elevation — typically 1,000 meters and above — where cool mist, slower growth, and hand-picking produce a floral, creamy, often buttery cup. It is usually lightly oxidized and ball-rolled.

In our latest data, Taiwan accounts for 91% of gaoshan oolong with a named origin — especially mountain areas in Nantou and Alishan.

Gaoshan oolong shines in gongfu style — short infusions in a gaiwan or small teapot, with many rounds as the rolled leaves open.

1. Use 5–7 g of leaf in a gaiwan or small teapot (100–120 ml).
2. Rinse the leaves once with water at 95°C (203°F) and discard immediately.
3. Steep the first infusion for 15–30 seconds, then pour off fully.
4. Add 5–10 seconds per subsequent round; good gaoshan often yields 6–10 infusions.

Elevation, harvest season, and cultivar are the most useful fields. About 45% of what we track names a cultivar and 23% names a producer or garden — Qing Xin (also spelled Qingxin) appears most often among cultivars.

Spring and winter harvests dominate where season is listed. Look for specific mountain names — Alishan, Lishan, Shan Lin Xi — rather than generic "high mountain" alone.

Qing Xin is the cultivar most associated with premium gaoshan, though Chin Shin Oolong and Si Ji Chun also appear. Titles often combine mountain name, elevation, and harvest season.

Lightly oxidized, unroasted styles dominate the category. Some lots note hand-picking or organic farming. Use the browse table below to compare how shops label their high-mountain teas.

Taiwan accounts for 91% of gaoshan oolong with a named origin. Nantou County and Alishan are the regions we see most often, with Lishan and Shan Lin Xi appearing on premium lots.

The best-documented teas name a specific garden and altitude — for example, Qing Xin harvested at 1,500 meters in Shan Lin Xi, or gardens above 1,800 meters in the Alishan range.

Gaoshan oolong typically tastes floral, sweet, and buttery — the profile of slow-grown high-elevation oolong with light oxidation. Creamy and fruity notes appear often as well.

One seller describes Qing Xin gaoshan as offering a "distinctive fruity, slightly tart flavour" after light processing — typical of the style when oxidation is kept low and roast is minimal.

Gaoshan oolong follows the classic oolong process — withering, bruising, partial oxidation, kill-green, rolling into tight balls, and drying — with light oxidation and minimal roast to preserve floral aromatics.

Hand-picking is common on mountain gardens where machine harvest is impractical. Some lots note vacuum-tight rolling or specialized processing; spring harvest at altitude remains the quality benchmark.

Gaoshan oolong mostly sits between $24.69 and $60.00 per 100g, with a median of $38.62 — premium relative to everyday oolong, but below the rarest Yan Cha or aged teas.

Sort the browse table by price per gram to compare on equal footing. Elevation, cultivar, and harvest season all correlate with price — single-garden spring Qing Xin from a named peak commands the upper band.
