Yes! I just received 100 g "sample" from Yunnan Sourcing yesterday! It tastes like a decent pu erh shu. Shu mostly tastes the same to me, but I plan to do a couple of side-by-side comparisons in the next few days, so hopefully I'll refine my pallet and give you a more detailed tasting.
I described the tea in this post
in today's TeaDay thread.
ETA: The traditional way to enjoy this tea is to boil it with milk and salt, as described here
. So far I've just tried it western style without milk. Made several nice infusions. I rinsed it well first!
