Every part of TeaHQ, grouped the way the catalogue is actually organised. Counts are read from the catalogue itself, so this page cannot claim more than exists.

What tea is

The plant, the six categories it becomes, the named teas, and the things drunk beside them.

  • The six categories of true tea, and what actually separates them.

  • Teas302

    Named teas: botany, origin, processing, brewing and character.

  • Flowers, leaves, roots, spices and grains drunk as infusions — identity, history, culture and preparation.

  • Prepared beverages and blends, from masala chai to bubble tea.

Where it comes from and how it is made

Countries, growing regions, the cultivars planted in them, and the processing steps that turn a leaf into a category.

  • Withering, kill-green, oxidation, wet-piling, roasting and drying.

  • Tea-producing countries.

  • Named regions and their terroir.

  • Cultivars within Camellia sinensis.

  • Production, trade and price as dated, sourced figures — with the two incompatible measurement bases kept apart rather than averaged.

Making it

Methods, the vessels each one needs, and what to do when the cup comes out wrong.

  • Gongfu, western, whisked, cold brew and more.

  • Gaiwan, yixing, kyusu, chawan and the rest.

  • Diagnose and fix what went wrong in the cup.

Understanding it

Guides, ordered paths through the catalogue, side-by-side comparisons, the chronology, culture, and the vocabulary.

  • Foundational how-it-works and how-to guides.

  • Ordered paths through the catalogue, each step explained by an authored link.

  • The words on a tea label, and the ones that are routinely used wrongly.

  • Side-by-side, including the pairs people confuse.

  • Ceremonies, regional customs, trade and history.

  • What happened, when, where, and how well anybody actually knows — a chronology of tea with every date labelled for what kind of date it is.

  • What is in a tea leaf, what each compound does in the cup, which processing step creates it and which brewing decision extracts it. Never what it does in a body.

What people drink it for

Why particular plants appear under functional searches, and who has drunk them for what — recorded as tradition, market and composition, never as evidence that anything works.

  • Why particular teas and plants appear under functional searches — which tradition, which market, which fact about the leaf. Never whether they work.

  • Who drank which plant, where, in what form, and what each tradition says the practice is for — recorded tradition by tradition. Never whether it works.

Working it out

Deterministic calculators that show their reasoning rather than returning a number.

  • Calculators and deterministic tools.

  • Tea finder

    Narrow the whole tea catalogue by what you like.

  • Compare

    Two things you have already chosen.

  • Brew assistant

    Authored parameters for a tea and a method — never converted between methods.

What TeaHQ has not opened, and why

  • Herbal infusionsTisanes — not Camellia sinensis, with their own safety model.
  • ScienceWater, extraction, oxidation and sensory science.
  • MythsCommon tea claims, checked against current evidence.
  • Tea and healthCaffeine, iron, pregnancy, interactions — the safety layer.
  • Flavour and sensory vocabularyTaste, aroma and mouthfeel as three separate senses, the words for each, and where each note comes from.

Two of these are the safety surfaces. TeaHQ writes about what a plant is, where it comes from and how it has been used; statements about what it does to a person sit behind a human review that has not happened, and the records stay unpublished until it does. The editorial policy explains the arrangement, and sources and evidence shows the register it rests on.
