When I visited Imperial Tea in San Francisco, greens were served this way -- in one gaiwan. When you had drunk most of the first steep, you were suipposed to add more hot water from a carafe -- to keep the steeping going and avoid bitterness. Is this the traditional way of doing it?
Myself, I like the idea of having 2 gaiwans, and pouring off the liquor, when steeped, into the empty one for drinking. And then pouring water onto the leaves for subsequent steeps.
