Same for me. I like drinking white jasmine tea, but the flavor becomes too bitter if you pour boiling water over the leaves. It’s better to drink at 80 or even 70 degrees (sorry, don’t know the F one).

I used to make tea for my coworkers back when we had a team room and got way into it. I had my own little kettle, all kinds of tea leaves, a weighing scale spoon and even a thermometer :)
I learned that pre-heating your kettle was important for black teas because boiling water would drop to 90 degrees or even less if you didn’t.
