Where it grows

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

• Nangang — 50–400 metres

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

• Pinglin — 200–800 metres

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

• Wenshan — 300–800 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.

• Wuyi — Camellia sinensis var. sinensis

  Upright growth and a clean, green-floral aroma. Used chiefly for Wenshan Baozhong and other lightly oxidised northern Taiwanese teas.

• Da Ye Wulong — Camellia sinensis var. sinensis

  Large, thick leaf with good vigour and tolerance of poor soil, but less aromatic refinement than Qing Xin. Small remaining planted area.

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. Bruising (shaking) — Ruptures cells selectively at the leaf margin, initiating localised enzymatic oxidation while the leaf centre remains unoxidised.
3. 3. Kill-green (fixation) — Denatures polyphenol oxidase and related enzymes, arresting enzymatic oxidation.
4. 4. Rolling and shaping — Ruptures cell walls to expose leaf juices, and forms the leaf into the shape it will hold through drying and storage.
5. 5. Drying — Reduces residual moisture to a level at which enzymatic, microbial and oxidative change effectively stops, stabilising the leaf for storage.

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.

• Light strip oolong — The missing corner of the oolong grid. Shape and finish have been a matched pair in every oolong route so far — pellet with a bake, strip with a roast — and this is the fourth combination: a loose twisted leaf that is never roasted.

  Where it is practised: The Wenshan district of northern Taiwan above all, where it is the local speciality rather than one style among several. Made on a small scale elsewhere in Taiwan and in Fujian, where the lightly oxidised strip styles run into the green-tea trade at their edges.

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
• Bruising (shaking)
  • converts Leaf lipids
  • creates Theasinensins
  • raises Indole
  • raises Jasmine lactone
  • raises Linalool
  • raises Nerolidol
• 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
• Drying
  • creates Strecker aldehydes
  • raises Beta-damascenone
  • raises Thearubigins

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

Named for the paper in which it was wrapped for sale — bao zhong means 'the wrapped kind'. It was made in Fujian before the technique moved to northern Taiwan in the nineteenth century, where it has largely stayed.

Common mistakes

• Storing it long — light oolong fades faster than roasted styles

When the cup goes wrong

Written against oolong as a category rather than against this tea in particular, and worked back from the symptom to the likely causes in order. 18 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 cold brew tastes like faintly flavoured water — After a night in the fridge the jug is pale and tastes of very little, with none of the sweetness cold brewing is supposed to give.
• 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 brewing falls apart when I have guests — Sessions that work perfectly alone become chaotic with three or four people: the tea is inconsistent, the pours are rushed, and the cups arrive at different strengths and temperatures.

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.

• Balhyocha, black tea and light oolong — A Korean tea that is filed as black tea, made by a route that does not map onto the Chinese categories, and sits genuinely between three of them. It is the clearest case in the catalogue of a tea the classification system cannot hold. Put the two side by side
• Baozhong vs green tea — Baozhong is the lightest oxidised oolong there is, and the question of whether it is really an oolong at all is a reasonable one to ask. Put the two side by side
• Darjeeling vs oolong — Darjeeling first flush is so lightly oxidised that the category boundary is worth questioning, and comparing it with an oolong shows why. 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.

• Taiwanese tea art (chayi) — A deliberately constructed Taiwanese tea practice of the late 1970s onward, which invented the aroma cup, popularised the fairness pitcher, and built a competition-grading system that moves prices more than any tasting note does.
• Wu-wo tea gathering — A Taiwanese group format from around 1990 built on a set of rules designed to remove status from a tea gathering: seats drawn by lot, everyone brews, everyone serves in one direction, nobody chooses what they receive, and nobody talks.
