If you use teabags, try to find a whole leaf teabag, not tea made from broken leaves and dust. Makes all the difference in the world. I drink black tea, with honey and orange juice. For hiking, I use honey powder (from packitgourmet.com) and a packet of True Orange crystallized orange juice. Not perfectly like a cup at home, but pretty close. I've found a good English Breakfast tea at Safeway that comes in tea bags that aren't individually wrapped, so I just have the tea bag to contend with, no extra wrappers.
My family used to drink Star of Singapore blend from Starbuck's, way back before they became the big espresso company, and still had good quality teas, not the dreck they have now. It was a blend of Ping-suey, Darjeeling, Yunnan something-or-other, and something else. When the company decided to ditch teas in favor of concentrating on coffee, my mom complained and got the recipe from them. We used to blend our own, then couldn't get the Ping-suey anymore, unless we bought a chest of it. A "chest" of tea is some ridiculous amount like 150 pounds of tea. Too much for private use!
