2 tsp for 500mL water @ 90C, steeped four minutes.
I got two excellent infusions: lots of body and flavour. The oolong itself is mild and slightly floral. The ginseng powder is lovely, just sweet enough, with plenty of ginseng lift. I expect I could have gotten a very good third infusion, too.
Dry leaf: little green pebbles. Cute.
Wet leaf: deep dark green, shiny.
Liquor: pale yellow and a slight green tinge for both infusions. Light to medium body. Some “bite” from the ginseng, which I really like. I’ve not been able to get ginseng oolong for at least a year, so this was a treat. I’d recommend this without hesitation.
