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 is a multi-infusion style. The schedule below is authored to 1 infusions; beyond that, extend each steep noticeably rather than repeating the last time.

  1. Infusion 1210sThree and a half minutes. The scent arrives before the tea does and the first sip is mostly aroma, which is the point.

Equipment

  • Travel infuser bottle
  • Vacuum flask
  • Chinese lidded mugThe lid holds heat through a long slow drink and, tilted, holds the leaf back while you sip — which is why the inner basket is optional.
  • Double-walled glassAn air gap keeps the outer skin holdable while leaf sits in near-boiling water all morning.
  • Hot water boilerTopping up all day needs hot water available all day, which is what the insulated boiler is for.

Vessel: A glass with a lid if one is available, or a saucer over the top for the first few minutes. The aromatic fraction is volatile and an open glass loses a good deal of it in the first minute — this is the one grandpa case where covering the vessel is worth the trouble.

Note: Ordinary Chinese green-tea numbers, with one difference that matters: a scented tea keeps giving aroma across a top-up in a way an unscented green does not, because the aromatic material is distributed through the leaf rather than being a first-infusion top note. It is the most rewarding tea in the catalogue to drink from a glass all afternoon and the least rewarding to brew once and discard.

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.
