Well I have to admit I'm a Redbull connoisseur, and what the
website says is true, the differences are evident between country to country, not because of taste but because of the vitamin mix. I've tried (in order of preference) Redbull from Poland, Spain, UK, America, and Thailand. What really makes it best is the B6 to B12 ratios used in the drink. The Thai stuff is rated lower, because it's a syurp like version that's supposed to be mixed with soda-water... it's ok (albeit a little strange) straight out of the bottle, but I could never mix it right with anything. I've heard that the original Austrian stuff is the best, but I have yet to taste it.
Speaking of taste, I've grown to love the apple-esque taste of it, but I always keep in mind that Rebull is a tool,
not a soft drink! If you are having one, or two a day you're not thirsty or tired, you're a junkie.
I love this stuff so much once every two months or so I go with a few friends down to Buffalo and split the purchase of a case or two with them. I just hope it comes to Canada soon...and in the Austrian version too!
