I actually purchased this at World Tea Expo last year from the Hankook Tea booth. It was an odd sorta beast – powdered Korean sejak leaves. But they did their best impression of a Japanese matcha I’ve ever come across.
The stuff fluffs up nicely into bubbles when whisked, the color is pretty, and the taste is very…uh…sejak-ish with more of a matcha kick. Basically, like a green tea espresso.
I’ve practically been emptying my li’l tin of this stuff for the last two weeks while various plagues have gone through both my apartment at work. So far, I’m holding up fine…if a tad bit over-caffeinated.
One such over-caffeinated adventure can be found here: http://steepstories.com/2014/03/07/teaity-chat-adventure/
