Bancha

Where it grows

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

• Shizuoka — 20–800 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.

• Yabukita — Camellia sinensis var. sinensis

  Balanced rather than distinctive: a dependable base for sencha, which is precisely why it was planted so widely.

• Zairai — Camellia sinensis var. sinensis

  Variable leaf, deep taproots from seed, late budding and low yield. Frost-hardier than many named cultivars and often found on marginal or abandoned plots.

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. 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.

• Japanese steamed green tea — Fixation by steam within hours of plucking, then a rolling sequence that dries and shapes at once — and then a second factory that turns one intake into four named teas.

  Where it is practised: Almost all Japanese green tea. Also the route for Chinese steamed greens such as Enshi Yu Lu, which use the same fixation and none of the refining tail.

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: Aluminium, Catechins, ECG (epicatechin gallate), EGCG (epigallocatechin gallate), Flavonol glycosides, Fluoride, Green-leaf volatiles, Manganese, Organic acids, Tea saponins.

• 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
• 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.

• Dobin — A larger Japanese pot with an arched handle of bamboo or cane across the top, made for serving several people rather than for careful single-cup brewing. It is the everyday household vessel for roasted and coarse teas, which want volume and boiling water rather than restraint.

Common mistakes

• Paying sencha prices for it
• Expecting sencha’s umami and finding it thin

When the cup goes wrong

Written against green tea as a category rather than against this tea in particular, and worked back from the symptom to the likely causes in order. 37 apply to the category; the first 6 are shown.

• I bought a big bag to save money and it was stale before I finished it — A large quantity bought at a good unit price faded well before it was drunk, so the saving turned into waste.
• I bought a water filter for my tea and it changed nothing — A filter jug or tap filter was bought specifically to improve the tea, and the cup tastes the same as it did before — with the same dullness, the same film and the same scale in the kettle.
• I have too many teas open and most of them are going stale — A dozen or more packets are open at once, three or four get drunk regularly, and the rest fade quietly on the shelf until they are thrown away.
• Leaves stick to the cup, the pot and my teeth — Fine leaf clings to the inside of the vessel, comes through into the cup, and ends up in the last mouthful.
• My bamboo whisk is losing tines — Fine bamboo tines snap off during whisking and turn up in the bowl, and the whisk feels stiff and splayed.
• 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.

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.

• Bancha vs sencha — The same bushes, different harvests. Bancha is what sencha production leaves behind, and it is considerably better than that description implies. Put the two side by side
• Hojicha vs Bancha — Hojicha is made from bancha, so they are not alternatives so much as before and after. Roasting is the only step between them and it changes almost everything. Put the two side by side
• Sencha vs bancha: what the price buys — The same bushes at different points in the season, and the price gap is larger than the quality gap for a lot of everyday drinking. 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.

• Everyday Japanese tea — What tea actually is in Japan for almost everybody — free with a meal, bought cold in a bottle, made by the litre in a jug at home — and how far that is from the practice foreign readers have been taught to think of as Japanese tea.
• Japanese tea farming practice — A highly mechanised, tightly specified growing and processing culture organised around cultivar selection, shading and steaming — and a smallholder structure that is under real demographic pressure.
