Standardised tasting set vs gaiwan
Two lidded vessels used for evaluating tea, with opposite goals. The tasting set is designed to prepare several teas identically, deliberately over-brewing them so faults show; the gaiwan is designed to show a tea at its best and to change what it shows from infusion to infusion.

What is being compared
Point by point
| Aspect | Standardised tasting set | Gaiwan |
|---|---|---|
| Goal | Comparability. Every tea gets the same treatment whether it suits it or not. | Expression. Parameters are adjusted to the tea in front of you. |
| Steep length | Long and fixed — the method produces a deliberately harsh liquor. | Short and variable, from a few seconds upward. |
| Number of infusions | One. | Many, and the change between them is the information. |
| What it reveals | Faults, and differences between lots under identical conditions. | What the tea can do, and how it evolves. |
| Who uses it | Buyers and industrial tasters, working through many samples. | Drinkers and sellers showing a tea. |
| Material | White porcelain, unglazed on the foot, in a lidded pot and matching bowl. | Porcelain, glass or glazed stoneware. |
The short answer
A tea that tastes good in a tasting set is unusual and a tea that tastes good in a gaiwan is expected, which is why professional and enthusiast tasting notes so often disagree. Neither method is dishonest; they are asking different questions, and only one of them is asking what the tea will be like to drink.
