It makes one wonder. Does the ideal tea exist at a constant temperature, or is the flavor an ever moving // evolving construct as the tea cools.
Definitely, tea flaover changes with temperature. Obviously, you can change the flavor by pouring boiling water right away after boiling point (which is not ideal), or pour it over 30secs later and you will already feel the difference.
Then, when in a cup, I can feel the difference, with hot tea, or lukwarm - flavor changes a bit.
