Seems to me a "hot" market niche for some entrepreneur.
Here on the West coast, we have Tejava and other brands.
There is now unsweetened iced tea in some stores. I bought my first bottle about two weeks ago in the Philadelphia region, although it was in one of those expensive, upscale grocery stores. Forget its name. We’re not good customers, though, because I make my own tea almost daily and nothing we buy is as good.
Because it is a pain to have to add sugar to a bottled beverage. Can you imagine Coca Cola without the sugar (or now, HFCS)?
I don't know why, but it drives me crazy. As a diabetic, I want the unsweetened or the artificial sweetener and they are hard to find. I'm a big tea drinker, but I like my tea 'straight,' no mixing with wild flavors, or even lemon.
I finally had to get used to diet peach ice tea because it was the only thing I could find (Snapple brand) in most stores if I was about and about.
I have started using the Crystal Lite tubes that you can add to water. I buy a variety of flavors (they have a peach tea) and keep them in my purse and desk. Since you can always find water these days, I just empty the tube in the water and I have a nice, no sugar, flavored drink.
