I’m a Red Bull man. (Boy that sounds strange to say). When I want caffeine and energy I normally drink Red Bull Sugar Free. I’ll drink the sugar full if I have to, but prefer to not have an insulin response paired with my stimulants.

Now I’ve decided to branch out and since I haven’t written a post here in a long time, I decided to write a quick review of the drinks I’m trying.

The first one was Rockstar Energy Drink. And the first thing I noticed was the can size.

I know when we American’s got into the energy drink business – following Red Bull – we did the typical bigger is better thing. But I’m used to drinking the small Red Bull cans, so any of the American drinks look huge. Do I need that much? Not really. And do I need that much caffeine? I doubt it.

Second thing I noticed was color. I like to drink out of glass, not a can. So when I’m home, like today, I’ll poor my drink in a glass. RockStar Sugar Free looks just like Red Bull, with the iconic bright yellow color.

The taste is also very similar to Red Bull, this is very much a knock off in my opinion. Probably not quite as tart, but it still makes you pucker on the first drink.

My final conclusion is it would be an OK substitute for my normal SF Red Bull. Taste is similar and everything else is the same. But if it isn’t cheaper, I doubt I’d pick it over Red Bull.
