I have finally discovered the right treatment to masque the floral notes of green oolongs.
On the one hand, this is sweet. Not a leaf with a sweetness to it, but actually sweet. I assume part of the ginseng treatment involves a sugar of some kind. This is not just on the tongue, but there is a burnt caramel sugar aroma both in the cup and from the liqueur.
Alas, I radically over steeped my second cup. :-(
