If you can find it in your area, Tejava (by the Crystal Geyser company) is the best bottled iced tea I've found to date. I am also an ice tea fanatic, having had my last sugar-soda some years ago. Tejava is just tea; no sweetener, no flavoring, no musty flavor that most bottled iced teas have. I buy it by the case from the local Trader Joe's for 0.99 per liter bottle, and drink it down fast enough to jeopardize my two liters of water a day...

Hope this helps.
