Overbrewing could be a factor. Most Chinese green teas are not that sensitive about slight temperature differences. But when you use a gaiwan, for most green teas, just don't have the lid on. Lid on can boil and "steam" the tea and that causes most over-brewing effect.Vulture wrote: Yah I tried them at work so I couldn't control temps well. It might just be the vegital is the overbrewing/badbrewing taste that comes from greens. Kinda like the bitterness in blacks.
Gaiwan is designed to occupy both of your hands, especially when used for green tea. When using gaiwan, with one hand grabbing saucer, one hand grabbing lid, tea drinkers can chat with others, or just stare at the air, but not allowed to do anything else
But overall it's hard to name gateway green teas. Sorts of green teas are more than all sorts of black/oolong/puerh teas added together. So no green tea can be representative.
