Chiang Mai
The northern Thai highlands where indigenous assamica grows in forest stands, historically managed for miang rather than for a drink: young leaf is steamed and packed to ferment, then chewed as a stimulant and social offering. Modern planting has added conventional green and black manufacture alongside, but the miang forests are the older layer and the reason Thailand counts as a tea origin at all rather than an importer of the practice.
Elevation
Recorded at 700–1600 metres.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it.
When it is picked
Two products on two calendars. Planted oolong follows the cool-season-preferred pattern; miang, the fermented chewing tea made from forest trees, is picked from mature leaf and needs the coarse material a quality pick would reject.

How the name is written
Also transliterated as chiang mai. 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
- Miang — Sour and savoury, and primarily a food rather than a drink. The infusion recorded here is the minor use, not the main one.
Other growing regions in Thailand
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.
- Chiang Rai vs Chiang Mai — Northern Thailand grows tea two ways that have almost nothing to do with each other. Chiang Rai’s oolong industry exists because Yunnanese communities who settled the ridges around Doi Mae Salong later imported Taiwanese cultivars; Chiang Mai’s highlands hold indigenous assamica managed historically for miang rather than for a drink.
- Shan State vs Chiang Mai — Two neighbouring uplands holding the same old large-leaf stock and the same tradition of eating tea rather than drinking it. Myanmar’s laphet and Thailand’s miang are parallel practices, and both are anaerobic fermentations of steamed leaf that have no equivalent in the six-category model.
