Preparing tea requires a certain amount of precision when it comes to professional tasting. If you are preparing to taste and compare a number of teas, it is essential that the infusion takes place in exactly the same conditions for them all.
So everything is done with attention: the water must be at the correct temperature, the recipients must be clean and of the same colour. The exact same quantity of leaves is placed into each pot, to the nearest tenth of a gram. Then the infusion can begin – timed, of course.
