Brew assistant

Pick a tea and a brewing style. Everything below is transcribed from that tea's own authored parameters — nothing is scaled from another style, because a ratio and a steep time do not transfer between styles.

Infusion schedule

This style is authored as a single infusion. A second steep from the same leaf will be thinner rather than merely weaker.

  1. Infusion 1480sA simmer, not a steep. Add the broken brick to water already boiling — the long climb from cold drags a dull edge out of dense leaf.

Equipment

  • Kettle
  • Brewing saucepan
  • Tea strainer
  • Tetsubin (unlined iron kettle)
  • Teapot warmer
  • Boiling teapotThe vessel for boiling rather than steeping: heat-resistant, wide-based, and made to sit on a heat source with the leaf in it.
  • Electric ceramic tea stoveA radiant plate takes the glass and clay vessels that boiling calls for.
  • Induction plateWorks only with ferromagnetic material, so an unlined iron kettle is fine and the glass boiling pot beside it is not.

Vessel: A kettle or open pan that can hold a simmer, with a strainer at the pour. The kettle is also the practical argument for the method: it serves a table, which a gaiwan does not.

Note: Eight minutes suits a brick broken into flakes; a piece left in lumps wants longer, and the tell is body rather than colour, which arrives long before the tea does. Boiled dark tea gives thickness and almost no top-note aroma — that left the leaf several infusions ago and no amount of heat brings it back.

What this does not tell you

  • These parameters are a synthesis of common practice rather than recorded practice for this specific tea.

  • How many infusions this tea will give beyond the schedule below is not recorded.

  • No caffeine estimate is authored for this tea, so the assistant cannot tell you how strong the cup will be in that sense.

  • Leaf weight is a weight. A teaspoon is not — a fluffy white tea and a tightly rolled oolong differ several-fold by volume, so scales beat spoons here.

Methods TeaHQ describes but cannot give numbers for

1 of 28 brewing methods have no authored parameters on any tea. They are listed rather than hidden: the method exists and is described, the numbers are simply not written yet. Nothing here is estimated from a neighbouring style.

  • Herbal infusion (tisane)

Herbal infusion is on that list for a second reason as well: the herbal catalogue is two records held in review, so there is nothing to brew even once parameters exist.
