I had 100 grams of the Summer 2005 Bai Hao, Oriental Beauty, from Gordon at DTH. What you are looking at is undoubtedly a more recent harvest, possibly even a different supplier, I am not a big fan of Bai Hao, and I have never tried the Adagio product, so my comment is prolly close to meaningless, but ....
Early last year, I found it to be pretty sweet (typical for BH) smooth like cream soda, a little smokey. It made me think of the vanilla center of a chocolate, but without the chocolate. I also found off and on, fruity (peachy and apricot) grain and it offered a little viscosity. It was clearly not a great Bai Hao, but it gave me something to think about and was a notch above those sort of namless "Formosa Oolongs" sold by the big tea companies in the USA.
If you like this sort of flavor profile, you will probably enjoy it as a frequent little treat at a reasonable price. If you want the best of Bai Hao, you will be disappointed and would be better off looking at someplace like TeaMasters or one of the more boutique online stores specializing in Taiwanese tea and expecting a much higher price tag.
Good luck ... and happy birthday in case I forget over the next 3 months.
