Aged white tea cake

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.

• Fuding — 100–800 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.

• Fuding Da Bai — Camellia sinensis var. sinensis

  Very large, heavily downy buds and a plump leaf. Sweet and hay-like when withered and dried, and vigorous enough to have been propagated well outside its home county.

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. Drying — Reduces residual moisture to a level at which enzymatic, microbial and oxidative change effectively stops, stabilising the leaf for storage.
3. 3. Compression — Reduces the leaf’s exposed surface area and fixes it in a stable physical form, slowing and evening out subsequent change.
4. 4. 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.

• Pressed and aged white tea — The withered-and-dried route with a pressing tail bolted on, borrowed wholesale from dark tea and applied to a leaf that was never fixed and never rolled.

  Where it is practised: Fujian, chiefly Fuding, and increasingly Yunnan for large-leaf white material. The practice is recent enough that long-aged examples are scarce and the trade's expectations about them run ahead of the evidence.

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: 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
• Drying
  • creates Strecker aldehydes
  • raises Beta-damascenone
  • raises Thearubigins
• 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

Pressing white tea into cakes is a recent practice, spreading in the 2000s as the market for aged white tea grew. It borrowed the format from pu-erh, and the whole category of deliberately aged white tea is younger than most of the cakes sold as aged suggest.

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 blunt flat blade or awl for separating leaf from a compressed cake or brick. The technique matters more than the tool: the pick is worked along the layers to lift leaf out whole, never chopped downward, because shredded leaf brews bitter and unevenly.
• Hygrometer — A small meter reporting relative humidity and temperature, used by people storing dark tea for ageing. It is the one measuring instrument in tea whose value is in what it rules out: it tells you whether a cupboard is swinging wildly between conditions, which is the thing that damages stored tea most and is invisible without a record.
• Boiling teapot — Aged compressed white is one of the teas that gives more to a simmer than to a steep.
• Humidity control pack — Humidity is a variable people ageing tea manage deliberately rather than eliminate; the pack is one way of holding a chosen figure.
• Tea storage cabinet — Compressed white is the other category kept deliberately for years, on the same reasoning as pu-erh.

Common mistakes

• Paying for an age claim that cannot be checked
• Brewing it as gently as fresh white tea

When the cup goes wrong

Written against white tea as a category rather than against this tea in particular, and worked back from the symptom to the likely causes in order. 8 apply to the category; the first 6 are shown.

• 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 green tea tastes flat and looks dark in this house — A delicate green tea that tasted bright elsewhere comes out dull and heavy here, with a darker, browner liquor than it should have and none of its aroma.
• My leaf floats on top and will not sink — Dry leaf sits on the surface in a dry-looking raft, and the tea underneath is pale long after it should have been ready.
• 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.
• My tea tastes of the cupboard it was kept in — The dry leaf carries a note that does not belong to it — spice, coffee, cleaning products, or simply a generalised kitchen smell — and the same note comes through in the cup.
• My water is not the temperature the kettle says — The kettle is set to 80 °C and the tea behaves as though it were much hotter or much cooler, and the same setting gives different results on different days.

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.

• Fresh tea vs aged tea — Two white teas from the same material, one drunk young and one kept for years. The comparison isolates what ageing actually does, because everything else is held constant. Put the two side by side
