Shizhuo
The cluster of villages on the ridge below the Alishan forest railway, in Zhuqi township, Chiayi, and the core of what is sold as Alishan oolong. ‘Alishan’ on a packet is a mountain-range name rather than a defined area, and it covers gardens across several Chiayi townships at very different heights; Shizhuo is the band that the trade means when it means the real thing. Morning cloud rolls up the western scarp daily through the growing season, cutting afternoon sun and holding the day-to-night range wide — the conditions the whole high-mountain style is built on.
Elevation
Recorded at 1200–1700 metres.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it. Gardens sold as Alishan run from well under a thousand metres to well over 1,600; this band is the part the name is normally understood to describe.
Climate
Daily orographic cloud on the western face from late morning, a wide day-to-night temperature range and a short growing season — the standard explanation for the thick leaf and low astringency of high-mountain oolong.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it. A trade and grower account rather than a demonstrated mechanism.
When it is picked
Spring and winter are the crops that matter, and at this altitude the season is short: the daily cloud that rolls up the western scarp cuts afternoon sun and holds the day-to-night range wide, growth is slow, and the number of pickable rounds in a year is well below what the lowland gardens manage. That scarcity is a large part of what high-mountain oolong is priced on. Summer leaf from the same gardens is a different and much cheaper product.

How production is organised
Small family farms on steep ridge land, most processing their own leaf, with a competition and grading culture that supplies the pricing signal an auction supplies elsewhere. Because 'Alishan' is a mountain-range name rather than a defined area covering gardens at very different heights, the label does not distinguish between them — which is the practical problem a buyer has here and the reason village names circulate among people who care.

How the name is written
Also transliterated as shi zhuo, shizhuo, shizuo. 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
- Alishan oolong — Thick, creamy and floral with a cooling finish that carries on well past the swallow — the clearest example of what elevation does.
- 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.
Other growing regions in Taiwan
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.
