The first infusion tastes different because the dry leaves have not yet fully hydrated and opened, while the initial extraction removes a different balance of aromatic and soluble compounds than later infusions.
This is one of the most interesting aspects of Chinese tea brewing.
A good tea does not necessarily have one fixed flavor.
Its character can change dramatically from infusion to infusion.
The right amount of tea leaf depends on the tea type, brewing method, water volume, leaf shape, and desired strength, but a practical starting point is about 3–5 grams per 250–350 ml for Western brewing and around 5–7 grams per 100–120 ml for gongfu brewing.
These numbers are starting points, not universal laws.
The same tea can taste completely different when you change the leaf-to-water ratio.
The common advice that green tea must never see boiling water is just as oversimplified as the opposite claim that every Chinese tea should be brewed at 100°C.
Rinsing is common in some gongfu traditions, but it should not be treated as a mandatory rule for every tea.
For some teas, a brief rinse can prepare tightly compressed or rolled leaves and remove loose surface material. For others, especially delicate teas, throwing away the first infusion can mean discarding some of the most aromatic compounds.
White tea can taste bland because the leaf-to-water ratio is too low, the water is too cool, the infusion is too short, the tea is stale, or the tea's naturally delicate character is being mistaken for weak extraction.
White tea is often misunderstood because its reputation for delicacy can lead people to under-brew it.
If your oolong does not have enough aroma, the most common causes are incorrect water temperature, insufficient leaf, poor water, improper brewing, stale tea, or a mismatch between the tea's style and your expectations.
Oolong is particularly interesting because aroma is one of its defining strengths, yet aroma can disappear quickly when brewing or storage conditions are unfavorable.
