Where it grows

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

• Assam — 45–120 metres

  How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it. The Brahmaputra valley floor is close to sea level; figures here are approximate and should carry a sourced range before publication.

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. CTC (crush, tear, curl) — Comprehensively ruptures and cuts the leaf into uniform granules, maximising surface area and speeding both oxidation and later extraction.
3. 3. Oxidation — Allows polyphenol oxidase to act on leaf polyphenols after cell rupture, converting them into the larger coloured compounds that give oxidised tea its colour and body.
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.

• CTC black tea — The orthodox route with one slot filled by a different machine, and every other decision in the route reorganised around what that machine needs.

  Where it is practised: Assam, Kenya, Rwanda, Uganda, Malawi, Sri Lanka's low grades, Indonesia, Argentina, and the great majority of Indian domestic production. Nearly every teabag in the world contains tea made this way.

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
• CTC (crush, tear, curl)
  • raises Tea cream
  • raises Theaflavins
• Oxidation
  • converts Carotenoids
  • converts Catechins
  • converts ECG (epicatechin gallate)
  • converts EGC (epigallocatechin)
  • converts EGCG (epigallocatechin gallate)
  • converts Epicatechin
  • converts Linalool
  • creates Beta-damascenone
  • creates Beta-ionone
  • creates GABA (gamma-aminobutyric acid)
  • creates Linalool oxides
  • creates Tea cream
  • creates Theaflavins
  • creates Thearubigins
  • raises 2-Phenylethanol
  • raises Geraniol
  • raises Nerolidol
  • lowers Anthocyanins
  • lowers Theogallin
• 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

Spiced milk tea spread across India in the twentieth century, driven partly by the Indian Tea Association promoting domestic consumption of a crop grown almost entirely for export. CTC manufacture, developed in the 1930s, is what made it affordable at scale.

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.

• Brewing saucepan — An ordinary open saucepan, which is the correct and traditional vessel for every preparation where tea is boiled rather than steeped — masala chai, noon chai, butter tea, salted milk tea, boiled dark tea. It is listed because the equipment for the world’s most-made tea preparations is usually a pan, and catalogues of teaware tend to leave that out.
• Mortar and pestle — Whole spices are cracked rather than powdered, so they release into a simmer without turning the cup gritty.

When the cup goes wrong

Written against black tea as a category rather than against this tea in particular, and worked back from the symptom to the likely causes in order. 19 apply to the category; the first 6 are shown.

• My chai catches on the pan or boils over — A scorched note runs through the finished drink, or the pan foams over the moment your back is turned.
• My chai is harsh and drying rather than rich — The drink is strong enough but unpleasant with it: a rough, drying grip on the tongue and a flat cooked note, rather than the round sweetness a good chai has.
• My chai tastes of hot spiced milk rather than tea — The drink is pleasant and sweet and the tea is nowhere in it — no colour to speak of, no briskness, and nothing that would tell you tea had been involved.
• My iced tea has gone cloudy — Tea that was clear when hot turns hazy or milky once chilled.
• My iced tea tastes watery once the ice melts — The tea is good for the first mouthful and thin by the bottom of the glass.
• My milk curdles or separates in the tea — Flecks or threads appear when the milk goes in, or the surface breaks into small islands, and the drink looks grainy rather than smooth.

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.

• Masala chai vs plain black tea — Chai is a preparation, not a tea. Understanding that resolves most of the confusion about why the leaf sold for it tastes harsh on its own. Put the two side by side

Botanicals this connects to

• Ginger — Ginger is one of the standard masala chai spices, simmered with the CTC base rather than steeped.
• Cardamom — Cardamom is the spice most consistently present in masala chai across regional variations.
• Clove — Clove is a standard masala chai component, used in very small quantities.
• Cinnamon — Cinnamon — usually cassia rather than true cinnamon — is a common masala chai component.
• Black pepper — Pepper supplies background heat in masala chai rather than a flavour of its own.
• Cassia — The bark in almost every masala chai. It stands up to milk and long simmering in a way Ceylon cinnamon does not.
• Long pepper — Used in South Indian and Nepali spiced preparations, where its late-building heat suits a milk base.
• Nutmeg — Grated into spiced milk tea across the Caribbean and South Asia, added at the end rather than simmered.
