Shen's writing inspired me to try some of the same from Teaspring.

This wonder of a tea held up strongly to multiple infusions becoming
toastier, more chocolate and sweeter. The tea is a quite a bargain
$9.90 and I'm assuming it will last for quite a while.

Agreed on all counts. Seems like a good price per ounce/gram for a
pretty good tea. Wonder if this way of packing makes it cheaper at the
producer end? I bought a few, intending to give them away if they were
good. Turned out they're very good, so I might keep most of them to test
ageability with and without occasional re-roasting. (Paper package won't
mind, I'm sure.)

This appears and tastes like a very highly fermented oolong, but not too
highly roasted - just what I've been seeking for long-term storage
experiments. Will get back to you all around 2018.

It was interesting to observe a "taste expectation" when brewing this
cake. It looks so much like a big-leaf shu pu mini-bing that it took a
moment extra for the distinctive Wuyi taste to arrive on first sip.

Also, in this box, Nai Xiang Oolong. This one is probably with
smoothest of the "milk" oolongs I've tastes and the flavour, although
very delicate, more pristine and clear in the "milky/silky" tones.

I agree. In fact, I believe it's the best milk oolong I've tried yet.
I've even brewed it under sloppy/abusive conditions, and always got good
results even though it's very green by my standards.

I also tried Teaspring's Bai Ji Guan, which is also one of the very best
I've tried. Were I not committed to Pu-erh in my oral drip these days,
this could be the every-sunday tipple while listening to Midnight Special.
