I'm not into energy drinks, but I'm a weirdo who taste tests and compares alot of foods and drinks.. lol
So far, the two best-tasting brands of iced coffee that I have tried are the Caribou brand and the Carnation Natural Bliss brand. Those are the only 2 that actually taste like coffee and not liquid creamer.. lol
The International brand is okay, but it tastes like creamer.
