I love tea, pretty much all varieties, though I'm not that in to white teas or artificially fruity stuff. Never drank it until many years with my wife, whose family drinks a lot of tea. If I could just force myself to stop drinking soda I am pretty sure I could give it up for tea, but what can I say, I love soda too.
I swear by Harney & Sons; the majority of their teas are fabulous and quite rich in flavor, which I value a lot in tea. I especially love there Thai Rooibos, though I could recommend more.
At home, I brew tea (mostly loose leaf) in a blue tetsubin.
I live near the only tea plantation in the United States (in Charleston), and we recently went there to try some of theirs. They are the home of American Classic tea, which isn't my favorite brand, but whatever. They make a pretty good mint tea, which usually isn't a flavor I am hyped for, and I was able to get a lot of supplies.
