Has anyone else noticed some sudsy/frothy bubbles in their sheng pu?
I was making some sheng at home this weekend, and saw (not for the first time) some soapy-looking bubbles on the tea soup inside my glass teapot before I poured it. It's not soap in the pot -- I haven't washed it recently. Could it be the result of impurities, or is this to be expected, maybe the natural tea oils or something?
After pouring the tea, I rubbed my fingers on the inside of the pot, where the bubbles were, and sure enough, it did feel a little bit viscous/greasy/soapy. I could've been imagining things... but wanted to check with all y'all.
