Chiang Rai
Thailand’s northernmost province and the centre of its oolong industry, which exists because Yunnanese communities who settled the ridges around Doi Mae Salong after the Chinese civil war later imported Taiwanese cultivars and rolling equipment. Jin Xuan and Si Ji Chun grown at 1,000 to 1,500 metres are made in an explicitly Taiwanese idiom, and the tea is best understood as a transplanted tradition rather than an indigenous one.
Elevation
Recorded at 800–1600 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
Several picks a year with the cool-season ones valued highest, on the Taiwanese logic the district's oolong sector imported along with its cultivars. Rainy-season growth is fast and discounted.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it.
How production is organised
Small family farms, many descended from crop-substitution and highland settlement programmes, processing their own leaf and selling locally and to tourists — a small-grower-and-small-roaster structure rather than an estate one.

How the name is written
Also transliterated as chiang rai. 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
- Thai black tea — Close enough to a simple Dian Hong that the resemblance is the point — the plantings came from Yunnan and the tea followed.
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.
