Sheng pu-erh (raw)

Where it grows

The districts recorded against this tea, all of them in China. Elevation is given as the band the district is recorded at, not a measurement of the garden this leaf came from.

• Yunnan — 800–2200 metres

  How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it.

The plants it is made from

Cultivar is the level below the variety group: a named selection of the tea plant, propagated as clones from one parent. Most consumer writing stops at the country and the category, which leaves out the layer that decides how the leaf behaves before anyone picks it.

• Yunnan Da Ye Zhong — Camellia sinensis var. assamica

  Very large leaves, high in the compounds that make young sheng bitter and that later provide the substance for decades of ageing. The same material makes a notably sweet, thick black tea when fully oxidised.

• Yunkang 14 — Camellia sinensis var. assamica

  Vigorous, high-yielding large-leaf material. Its ubiquity in terrace plantings is precisely why gu shu and da shu claims exist as a market category — the contrast being drawn is usually against a Yunkang field.

How it is made, in order

Read top to bottom: the list is the production sequence, and the sequence is what makes this tea its category rather than a neighbouring one. The same leaf from the same bush becomes a green tea or a black tea depending on where the heat falls relative to the bruising, so reordering these steps would not vary the tea — it would produce a different one.

1. 1. Withering — Reduces water content, softens the leaf for later handling, and permits early enzymatic and aromatic development.
2. 2. Kill-green (fixation) — Denatures polyphenol oxidase and related enzymes, arresting enzymatic oxidation.
3. 3. Rolling and shaping — Ruptures cell walls to expose leaf juices, and forms the leaf into the shape it will hold through drying and storage.
4. 4. Sun-drying (shai qing) — Reduces moisture to a storable level at low temperature, leaving residual enzymatic and microbial activity in the leaf.
5. 5. Compression — Reduces the leaf’s exposed surface area and fixes it in a stable physical form, slowing and evening out subsequent change.
6. 6. Ageing and storage — Allows slow oxidative, microbial and thermal change to continue in stored leaf, gradually converting sharp young character into darker, rounder and sweeter character.

The route it is made by

The steps above are what happens; this is the named production route they belong to, with the other teas made the same way.

• Sheng pu-erh — A green tea route with one substitution — sun-drying instead of oven-drying — and that substitution is why a cake can change for decades instead of going stale.

  Where it is practised: Yunnan, and legally so under the Chinese geographical indication for pu-erh. Comparable sun-dried material is made in northern Laos, in the Vietnamese highlands and in Myanmar, and is pressed and sold under other names.

What its chemistry turns on

Every true tea contains caffeine, catechins and amino acids, so listing them would say nothing about this one. What differs is what the processing above does to them — and that is the same list of steps, read for its chemistry instead of its craft.

The compounds that substantially decide what this tea is: Beta-ionone, Carotenoids, Catechins, Gallic acid.

• Withering
  • creates Geraniol
  • creates Linalool
  • creates Linalool oxides
  • creates Theasinensins
  • raises Methyl salicylate
  • raises Nerolidol
  • raises Soluble sugars
  • lowers cis-3-Hexenol
  • lowers Green-leaf volatiles
  • lowers Leaf lipids
• Kill-green (fixation)
  • locks 2-Phenylethanol
  • locks Anthocyanins
  • locks Catechins
  • locks cis-3-Hexenol
  • locks Green-leaf volatiles
  • locks L-theanine
  • locks Leaf lipids
  • locks Methylated catechins
  • locks Theogallin
• Rolling and shaping
  • converts Leaf lipids
  • creates Theaflavins
  • raises Pectins
• Sun-drying (shai qing)
  • raises Beta-ionone
  • lowers Carotenoids
• Ageing and storage
  • raises Gallic acid
  • raises Pectins
  • raises Pheophytin
  • raises Thearubigins
  • lowers Catechins
  • lowers Chlorophyll
  • lowers Tea cream

These are statements about the leaf and the cup. What any of these compounds does in a body is a different kind of question and is not answered here or on the pages linked from it.

History

Compressed tea from Yunnan was traded north along the tea-horse road to Tibet for at least a thousand years, and compression existed to survive that journey rather than to age the tea. The discovery that the tea improved on the way is the origin of everything the modern pu-erh market is built on.

Vessels this tea suits

Recorded against the tea rather than against a brewing style, because the vessel does not always follow from the method — a whisk needs lateral room whatever the schedule says, and compressed leaf needs a pick before any method applies at all.

• Tea pick (cha dao) — A compressed cake has to be separated along its layers before any brewing method applies. Cutting rather than lifting shreds the leaf and makes it brew bitter.
• Hygrometer — A storage instrument rather than a brewing one: it tells you whether a cupboard is swinging, which is the thing a cake reacts to.
• Humidity control pack — Used by collectors holding a small quantity, where a whole room cannot be conditioned.
• Tea storage cabinet — A converted wine cooler is a serious piece of equipment for a narrow purpose: ageing tea over years rather than storing it to drink.

Common mistakes

• Full boiling water on young material, which makes it aggressively bitter
• Steeping for western-style minutes with gongfu-style leaf quantities
• Storing a cake in a sealed bag, which stops the ageing it was bought for

When the cup goes wrong

Written against dark tea and pu-erh as a category rather than against this tea in particular, and worked back from the symptom to the likely causes in order. 15 apply to the category; the first 6 are shown.

• Every infusion in my gongfu session tastes the same — The cups are pleasant and interchangeable, with none of the change from steep to steep the method is supposed to show.
• My clay pot has changed how the tea tastes — A tea that tasted right in porcelain comes out muted, differently scented, or carrying something that was not in the leaf.
• My first infusion is always the worst one — The opening cup is thin, dusty or flat, and the second is markedly better — consistently, across different teas.
• My gaiwan is too hot to hold — The rim and lid become uncomfortable within seconds, the pour is rushed, and tea ends up on the tray.
• My gongfu tea is bitter even at five seconds — The timer says five or ten seconds and the cup is over-extracted anyway, with the later infusions dropping off sharply.
• My pu-erh cake will not break apart cleanly — The cake resists the pick, then gives way suddenly into powder and fragments rather than intact leaf.

Compare this tea with another

Written comparisons

Where TeaHQ has set this tea against another in full, rather than deriving the comparison. Each one is a written page with the points of difference argued out.

• Aged sheng vs shou pu-erh — Ripe pu-erh was invented to imitate aged raw pu-erh. Forty years on, the question of how close it gets is the most useful one in the category. Put the two side by side
• Pu-erh cake vs loose pu-erh — Compression is a decision about the future rather than about the cup, and it is the main thing separating tea meant to be kept from tea meant to be drunk. Put the two side by side
• Sheng vs shou pu-erh — The two halves of pu-erh are made differently, taste almost nothing alike, and are bought for different reasons — but are sold under one name and constantly confused. Put the two side by side
• What is pu-erh? — Pu-erh is compressed tea from Yunnan that changes through microbial activity rather than oxidation. It splits into two halves that share a name and very little else, and knowing which one you have is the whole of understanding it. Put the two side by side
• Young sheng vs aged sheng — The same cake at two points in its life, and the reason people buy tea they do not intend to drink for twenty years. It is also the clearest illustration of why storage provenance matters as much as origin. Put the two side by side

Botanicals this connects to

• Yerba mate — Both are drunk in long social sessions with repeated refills rather than as a single cup, which shapes the etiquette around each.

Where this tea is drunk

Documented practices that name this tea. Each page describes what is done and by whom, and separates what is recorded from what is repeated.

• Bai three-course tea — A Bai hospitality sequence from the Dali area of Yunnan in which three cups are served in fixed order — bitter, then sweet, then a third that is neither — with the sequence itself carrying the meaning.
• Gongfu cha — A Chinese approach to brewing and serving tea built on small vessels, a great deal of leaf and many short infusions — practised today across a spectrum from everyday habit to formal hosting.
• Pu-erh ageing and collecting culture — A collecting and storage culture built around tea that changes for decades after it is sold — with genuine connoisseurship, a real market, and a speculative dimension that participants themselves disagree about.
• The Chinese tea table and its tea pet — The draining tray, the accumulated tools and the small unglazed clay animal that gets tea poured over it for years — the furniture of everyday Chinese tea drinking, and what its condition tells you about the household.
• The Ming loose-leaf reform — An imperial decision at the end of the fourteenth century to stop accepting compressed cake tea as tribute — after which Chinese tea became loose leaf steeped in a vessel, and almost every category and utensil now in use began to take its modern shape.
• The speciality tea community — A dispersed, largely online community that formed around imported loose-leaf tea from the 1990s — with its own vendors, group buys, session vocabulary and running arguments, and a habit of adopting other people’s practices without their contexts.
• The tea-horse trade — A state-organised exchange of Chinese tea for Tibetan and frontier horses, run through a dedicated government office for centuries — and a modern tourist name for the routes that is barely thirty years old.
