Teas named by place
Dark tea is a map of post-fermentation, and each region ferments toward its own market.
Pu-erh from Yunnan splits into sheng（生茶）and shou（熟茶）, raw and ripened.
Raw ages slowly on the shelf, and ripened is fermented quickly through wet piling.
Anhua dark tea from Hunan makes the fu brick（茯砖）with its golden blooms, jin hua（金花）.
It also makes the thousand tael log, a column of compressed tea wrapped in bamboo.
Liu Bao（六堡）from Guangxi is mellow, with a betel nut note its drinkers defend.
Ya’an（雅安）in Sichuan makes the brick bound for Tibet, sold by the piece rather than by weight.
Hubei adds the Qing brick, and Shaanxi makes a version of the fu brick of its own.
That is 5 provinces, 5 fermentations, and 5 markets that each wanted something else.
The shapes followed the journey, since a brick fits a horse and a log fits a boat.
The microbes followed the climate, since every region has its own house flora.
That is the real reason the regions taste different, rather than any story about terroir.
Why region matters
Region matters in dark tea because fermentation is a local event.
The microbes doing the work live in the room, and they differ from county to county.
A Hunan brick and a Guangxi basket are inoculated by different air.
Climate sets humidity, humidity decides which fungi thrive, and those set the flavour.
Altitude and cultivar still matter, since Yunnan’s large leaf gives pu-erh its structure.
But the fermentation is what separates the regions, and it cannot be standardised away.
Five provinces is a lot to taste, and most drinkers settle on one of them within a year.
A region earns its name by setting a standard, and Anhua did that for the golden bloom.
A factory built in a different climate does not reproduce it, whatever it prints on the wrapper.
Regional fame outlasts marketing, and here it outlasted the trade routes that made it.
The tea horse road is long gone and the brick is still made, which tells you something.
What a name buys you is a fermentation profile you can rely on.
It does not buy you storage quality, and storage is what ruins most of this tea.
When regions cross borders
Dark tea regions cross borders constantly, and this is where the category gets dishonest.
Pu-erh style pressing is done in Guangdong and in Malaysia as well as in Yunnan.
Leaf from Laos and Myanmar gets pressed and sold under Yunnan mountain names.
Some of that is good tea, and none of it came from the mountain on the wrapper.
The microbes travel with the technique, which is why the results land closer than you would expect.
Climate still shows through, and a cake fermented in Guangdong tastes unlike one from Kunming.
For honest buying, the region should name where the leaf grew and where it was stored.
Storage is the second geography in this category, and it matters as much as the first.
Ask where the leaf came from and where the cake has been since, and treat both as facts.
A seller who knows answers in a sentence, and one who does not talks about the mountain.
Blending across regions is normal and legal, and it simply needs to be described.
A blended cake is not a fake, and a fake mountain name is.
How to choose among them
Choosing among dark tea regions is choosing a flavour axis before anything else.
Yunnan for structure and ageing, and Hunan for the bloom and its dry sweetness.
Guangxi for the cellar note, Sichuan for the working brick, Hubei for the mellow green brick.
Pick the axis you like, and only then start looking at mountains and years.
Buy 25 g of each type, since a whole cake is a commitment you cannot taste your way out of.
Brew at 100 °C with 5 g in 100 ml, and rinse the leaf once before the first pour.
Run each one to 8 infusions, because the arc across a session is what you are buying.
Sub-regions come next, and in Yunnan they are villages with very large price gaps.
Go one level down at a time, and compare every expensive cake against a cheaper one.
That comparison is the only reliable way to learn what a mountain name is worth.
Stop when you cannot taste the difference, and not when the label stops impressing you.
Five provinces, one afternoon, eight infusions each, and a much clearer sense of direction.
