Indigo Tea Company
has a house tea called Indigo Blend
which is a blend of Yunnan and some form of Jasmine (their site is contradictory as to whether it's a black or a green; my feeling, from looking at the leaves, is that it's an oolong similar to Adagio's Jasmine #5
). I'm really enjoying it. (I just made a cup of it.)
As far as the alchemy, I don't really recall that discussion except for that it seemed to center solely on pre-flavored teas. It would be nice if, when the blending option is re-launched, we were able to blend unflavored black teas together as well.
