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 1300sSimmered in a kettle first. The strained liquor is then poured into a bowl and beaten to a foam with a twin-headed bamboo whisk — the leaf is never powdered, which is the difference from matcha.

Equipment

  • Chawan (matcha bowl)
  • Chasen (bamboo whisk)
  • Chashaku (bamboo scoop)
  • Tea cloth
  • Matcha sieve
  • Kusenaoshi (whisk stand)
  • Natsume (matcha caddy)
  • Hishaku (bamboo water ladle)
  • Gooseneck kettle
  • Ro and furo (hearth and brazier)
  • Jian ware tea bowl (jianzhan)The dark-glazed conical bowl was made for whisked powdered tea: white froth on a near-black ground is easy to read, which was the point of the contest it was made for.
  • Stone tea millNothing can be whisked until tencha has been ground, and the granite mill is what does it slowly enough to keep the powder cool.
  • Hagi wareA soft, crazed, open-bodied ware used for tea bowls, which visibly changes colour with use.

Vessel: A wide bowl and a double chasen. The twin heads are what make the noise the tea is named for.

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.
