Not something that I really enjoyed.. The rinse tasted like if you roasted baked beans over a campfire and could bottle that up in a taste-able form.. But then the steeps were super bitter to me at 195F. After a few steeps, nothing really changed, so I went to 175 and it was mellow and a little sweet. Too finicky for my tastes.
I never make sheng lower than 200F. Maybe you should try to up temps. You maybe rewarded with huigan after. Haven’t tried this tea though
