The formula
leaf = water ÷ 100 × grams per 100 ml
These are customary starting points and not rules. Every tea differs, and the seller’s own guidance usually suits it best. Too hot or too long is what mostly makes tea bitter.
What to watch out for
Change the time first if the cup is too weak or too strong, then the amount of leaf. For a lower temperature without a thermometer, boil the water and let it stand for a few minutes.

What is the standard way to brew tea for tasting?
ISO 3103 uses 2 g of tea per 100 ml of boiling water for 6 minutes. It is made for comparing teas, so it is stronger than most people drink.
