I have been happily studying/tasting tea for over ten years, and really love sharing teas with small groups, friends, and families.
I really love puerh tea - and am so grateful for Yunnan Sourcing so I can constantly sample quality ones. I also love their black teas, and their crazy selection of wuyi rock oolongs and phoenix mtn dancong teas. They also have this great new site I tried a few teas from called TaiwanSourcing.com ~ those teas were also exceptional.
I also love high quality organic herbal blends like those from www.Metoliustea.com ~ they have a few caffeine free blends like "North" that I am totally in love with. Also when I need a good cuppa Earl Grey, they make my favorite.
There is also a cool USA tea farm called MaunaKeatea.com -- I tried some of their stuff and was really impressed.
But over all I am a huge Yunnan/Taiwan fan for tea as well as tea pottery/wares.
