Fairly often when I am trying to figure out the right brewing parameters for a tea, I get a cup that is too much of something, but I can't always tell whether it's too strong or bitter.
Is there some way I can learn how to tell the difference?
I think I can recognize when it's gotten very bitter, because of the "bite". But when it's only slightly bitter, I have difficult distinguishing that from just too strong.
Also, some of the strong blacks, like Assams, have a taste that is (to me) a lot like bitter even when brewed for very short times.
Is it true that bitterness only occurs from steeping too long? I would think that no tea would be bitter in a 30 second steep no matter how much leaf is used. Is that right?
What I have done so far is try two more cups -- one at double the time and one at half the time. That usually makes it clear. But I'd like to learn to tell better just from tasting.
