Alishan
A high mountain area in central Taiwan and the best-known name in high-mountain oolong, where altitude and persistent cloud are credited with the thick, creamy, low-astringency character of the style.
Elevation
Recorded at 1000–1600 metres.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it.
Climate
Frequent cloud cover and a wide day-to-night temperature swing are the traditional explanation for the slow growth and thick leaf of high-mountain tea.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it. A traditional account rather than a demonstrated causal mechanism; recorded as such.
When it is picked
Spring and winter picks carrying the value, with the summer crop discounted. The mountain's persistent afternoon cloud is the condition growers credit for the district's character, and it also shortens the effective picking day.

How production is organised
Small family farms, many processing their own leaf, in a district whose name is applied far more widely than its planted area supports — 'Alishan' functions as a style label across a large part of central Taiwan as well as a place.

How the name is written
Also transliterated as alishan, ali shan. Romanisations of a district name vary by system and by vendor, and a packet spelling one way is not describing a different place.
Teas this region is known for
- High mountain oolong — Thick and almost milky in texture, with a floral sweetness and no grip at all. The cooling sensation in the throat afterwards — hou yun — is the quality marker practitioners look for.

The neighbouring districts are the useful comparison: they share a country, a grading convention and often a cultivar, so what differs between them is closer to terroir than anything a cross-border comparison can isolate.

Written comparisons
Where TeaHQ has set this region against something it is routinely confused with, and argued the differences out in full.
- Dong Ding vs Alishan — Taiwan’s traditional oolong hill and its most famous high-mountain one, separated by about a thousand metres and by an entire era of taste. Dong Ding’s roasted style predates the high-mountain fashion and is still the reference for what a traditional Taiwanese oolong is.
- Mingjian vs Alishan — The volume end and the prestige end of Taiwanese oolong, and the pair that explains how a cheap tea can smell expensive. Mingjian grows enormous quantities of Si Ji Chun at low elevation, and Si Ji Chun’s aroma is frequently mistaken for high-mountain character.
- Shan Lin Xi vs Alishan — Two Taiwanese high-mountain areas at similar elevations whose teas are described in almost opposite terms — one as the creamiest of the high-mountain oolongs, the other as the cleanest and most bracing. The difference is credited to what surrounds the gardens as much as to how high they sit.
- Wenshan vs Alishan — Both produce lightly oxidised Taiwanese oolong and they produce it in opposite shapes. Wenshan Baozhong is strip-rolled and barely oxidised, close enough to green tea to confuse a blind taster; Alishan is ball-rolled and high-grown.
