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.
Water temperature
4–10 °C
Typically 6 °C
Leaf for 250 ml
3.8–6.3 g
Typically 5 g
Ratio
1.5–2.5 g /100 ml
No rinse
Infusion schedule
This style is authored as a single infusion. A second steep from the same leaf will be thinner rather than merely weaker.
- Infusion 136000sTen hours, and the leaf will float for the first two of them. Push it under once rather than stirring repeatedly.
Equipment
- Glass teapot
- Cold brew bottle
- Plastic teaware — Most cold-brew bottles and travel brewers are heat-tolerant plastic: light and unbreakable, and a surface that takes up aroma from smoky, roasted and heavily scented teas.
Vessel: A wide-mouthed sealed jar rather than a narrow bottle. Downy white leaf traps air, floats, and packs into the neck of a bottle where the water barely moves.
Note: The longest steep among the leaf teas here, for a physical reason rather than a chemical one: the down on a white tea’s buds is water-repellent, so the material spends hours refusing to wet before extraction properly begins. White tea is the category most often described as an ideal cold brew and most often disappointing at it, and short steeping is why. Given the full time it gives a clean, melon-and-hay sweetness that hot brewing of the same leaf does not reach.
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.
