I have drunk many oolong tea, such as Tie Guanyin, Dahongpao and Taiwan oolong tea. But now I prefer the Wuyi Dahongpao.
Umm, I think the Assam tastes too strong for me.
I seldom drink the Japanese tea because most of them are green tea. But I'm going on buy some matcha online. As you said,matcha is more and more popular now, but I don't know whether blend it into leaf tip spencha teas or not. I think it a little complex.
