[This review was collected as part of a promotion.] My fiancé and I did a taste test and I have to say I am not a regular fan of Red Bull but this flavor really sold me! It taste just like cotton candy and there is no aftertaste. I normally drink Alani energy drinks and this had the same effect on me. Overall size was perfect. Probably one of the best Red Bull flavors I've had. In regards to sweetness as mentioned before really great taste tastes just like candy.

[This review was collected as part of a promotion.] This version keeps the same berry-vanilla flavor while cutting the sugar. It still includes caffeine and B vitamins for a quick energy lift. A nice option if you want something flavorful but lighter.

[This review was collected as part of a promotion.] Flavor wasn't bad with a hint of berry and nice smell but had a slight artificial aftertaste. I don't like diet sodas due to this same artificial aftertaste but if you like diet soda, you would probably be fine with this flavor. Also don't like that it has artificial dye in it (blue 1). I feel like dye is unnecessary. It is a pretty can though!

[This review was collected as part of a promotion.] I really liked the original of this flavor so I was hopeful for this one but instead of sugar or another natural ingredient, they used sucralose. This leaves a gross artificial taste and can be really hard for people with GI issues to consume. Very disappointed in it.

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.] Enjoyed this as a post-gym pick-me-up beverage. My boyfriend drinks sugar free redbull on the regular and it's not far off from that taste. Just less sour, with a floral vanilla note, and a hint more sweetness from the berry flavor. Boyfriend says it tastes similar to all the other red bull berry flavors. I like it because it tastes less acidic than regular sugar free flavor.

[This review was collected as part of a promotion.] This redbull flavor has the perfect amount of sweetness and energy needed to get me through my day. I drank this around 9am and started feeling the caffeine hit me around noon. I enjoy the zero sugar flavor as it makes it easier on the tastebuds to enjoy! I enjoy how this redbull didn't keep me up late at night or give me any anxiety like some energy drinks tend to do. Overall, easily one of my favorite flavors. The vanilla and berry combination make this drink very refreshing and energizing!

[This review was collected as part of a promotion.] It is not my favorite. The flavor is interesting, sweet with a hint of vanilla and berry but it can taste a little artificial at times. It's not bad but i wouldn't drink it again. My brother liked it though, so everyone has a different taste.

[This review was collected as part of a promotion.] The creamy vanilla notes in this Red Bull is a nice change from the fruit forward flavors of all the other limited edition Red Bulls. It's perfect for the fall and winter months. Being sugar-free is a nice addition and makes for a guilt free experience. I LOVE IT!!

[This review was collected as part of a promotion.] Sugar-free iced vanilla berry is my new favorite! The flavor is extremely there, especially for the size of the can! In my opinion, the vanilla is the most concentrated flavor in the mix, and I love the color and packaging of the can! Very appealing! Love this newer Red Bull flavor!
