Bulang sheng pu-erh

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.

• Bulang — 1200–1800 metres

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

• Lao Ban Zhang — 1400–1900 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.

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.

• 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

Bulang Mountain’s tea was ordinary Menghai material until the pu-erh boom of the 2000s, when single-village sourcing began and Lao Ban Zhang in particular became the most expensive tea in Yunnan. The reputation is real and about twenty years old.

Common mistakes

• Judging it before the returning sweetness arrives

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.

• Yiwu vs Bulang sheng pu-erh — The two poles of raw pu-erh character, and the pair that defines the axis every other producing area sits on. Between them they define the axis every other raw pu-erh producing area is described against. 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

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.

• 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.
