I just got back from China. They literally had the best tea I've ever had. Longjing (dragon well) tea is grown in Hang Zhou, and I got the privileged of visiting the tea village. You can actually eat the tea leaves once you've brewed a few cups with them. (btw, it's green tea, so it's super fresh and subtle.)
The Chinese family I was staying with also served me a cup of Pu'er tea. Best black tea I ever drank. Amazingly strong, almost like coffee.
