As an energy drink connoisseur, I can confidently say that the Sugar Free Iced Vanilla Berry is the best by far. Redbull already has the perfect caffeine content (not insane like those 200-300mg competitors) so I feel focused and not jittery. But this flavor blows all competition out of the water. It is sweet, juicy, and the addition of the vanilla gives it such a delicious depth of flavor. 10/10 always for Redbull, but this one gets an 100/10 for them figuring out the most perfect sweet sugar-free flavoring.

[This review was collected as part of a promotion.] I am a huge fan of Red Bull and love their sugar free drinks as a way to give me engery without the calories. The drink is refreshing and smooth and good while cold. I love the carbonation, this drink is easy to drink. After it got warm though I realized I didn't love the flavor but will certainly try more from the brand!

Not gonna lie, I wasn't a big fan of this one at first but it's grown on me. It's got a cotton candy taste to it almost in my opinion, not too sweet, good carbonation, good vibes over all. For me Redbull doesn't pack a punch energy wise like some energy drinks do but I think that's personal based on caffeine tolerance and such.

[This review was collected as part of a promotion.] This is by far my favorite red bull flavor! You really get a great mix of that smooth vanilla flavor as well as that kick of berry. The drink is so refreshing and perfect for summer! Definitely a 10/10 for me!!

[This review was collected as part of a promotion.] This is my new favorite redbull, I’ve only tried the watermelon and the original, so this was great. It tasted like a familiar candy, can’t put my finger on it but it’s really delicious. With all redbulls they never give me the jitters! Love the blue color as well lol. Definitely my new favorite!

[This review was collected as part of a promotion.] This drink was one of my favorites. &&& I can see myself keep buying these for now on. I can really taste the vanilla. && usually I just like my vanilla in my coffee. This is really goods usually flavor energy drinks I don't go for. But this one was really good. I will definitely will buy more of these in the future.

[This review was collected as part of a promotion.] I actually really like this, to me it tastes like cotton candy with a fruity twist. It is a little on the sweeter side for me, but honestly still good - especially for a sugar free drink, which is always a big plus. I had it one morning at work instead of my usual coffee and it actually woke me up and gave me a nice boost for the start of the day. Not something I'd drink every day because of the sweetness, but definitely a flavor I'd go back to in terms of red bull options.

[This review was collected as part of a promotion.] Very good! I mostly enjoy that it was sugar free with no weird after taste. Gave me the boost I needed to finish supper. The flavor was really good. Almost had a cotton candy flavor to it. I would repurchase this one!

[This review was collected as part of a promotion.] Personally was not a big fan of the taste - the berry flavor was stronger than the vanilla for me but tasted way too sweet. I can see this being a plus for fans of the original since this is the sugar-free version but still has such a strong, sweet flavor.

[This review was collected as part of a promotion.] Probably my new favorite flavor of Red Bull. It tastes like cotton candy and is so refreshing. It has good carbonation where it's not to much. I also couldn't tell this was sugar free. Pleasantly surprised.
