Cameron,

Interesting observation. I have not been brewing my oolongs in porcelain
lately; I have been using exclusively yixingware, and the lack of sweetness
I've noticed is something I've been ascribing to my current batches of these
teas. In fact, I've been changing temp and time parameters to try to bring out
different taste elements.

You've encouraged me to experiment with porcelain.

I'm interested in your interpretation of "yan" as well.
