I drink regular supermarket available tea. My favorite is Bigelow Constant Comment, with its orange flavor. My parents used to drink it and thus I have a sentimental attachment to it. I will add thqat it is especially good in the evening with rum in it and toast on the side. Serving suggestion, you know.
I also enjoy earl grey and darjeeling. Since I work at Starbucks I get Tazo teas too. I like their Passion and wild sweet orange herbals, though I doubt they are really teas at all because they steep so fast.
My husband is a Kentuckian and as a result I have become an expert on making iced tea. He used to drink this horrendously sweet sweet tea, but I have weaned him to black tea with fresh peppermint in it. I use Red Rose tea, six tea bags per gallon plus a bunch of fresh peppermint. If I am making it without mint I uise eight bags.
The best iced tea beverage I know, though, is Tazo Berry Blossom White tea lemonade. I make at least two gallons a day of this. I take eight bags of the tea, pour a half gallon of boiling water over it. Steep abput six minutes, then add a packet of Kool Aid lemonade and a cup of sugar and another half gallon of cold water. Don't cringe at the Kool Aid, it is delicious, refreshing, and has half the sugar and calories of most sweet drinks, even less than half if you drink some kind of pop.
