Well folks, my tea arrived. Here's the scoop:
Leaf: bright green, grassy nose. Liquor: (185F, 90 seconds, 2 rounded dessertsp/500ml) - pale orange, faint grassy/vegetal nose. In the mouth, no noticeable astringency when hot, as it cools a slight dryness is apparent. Soft flavor of leaves and grass, with a faint floral note. There's also something else in the background, an almost meaty note that, if it were any more pronounced would be off-putting. Fairly long finish, with a faint fruity/muscatel note.
Karsten suggested what I'd get was "water in the cup"; no, this tea has definite flavor, just muted. I flatter myself that if served blind I'd recognize it as Darjeeling, but it's got an unusual profile. An interesting experiment, but I'm not going back for more.
I also got some of Upton's new Bai Hao (ZO93); I'll report on it when I have a chance to taste it properly.
Regards, Dean
