Pressed 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.

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.

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.

• 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

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.

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.

• Humidity control pack — A cake pressed to be aged, at the point in its life where the storage decision is still open.

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.
