[This review was collected as part of a promotion.] My review is based on my husband’s response as he was the one who drank it. Sugar Free Red Bull has a sweet, but not overpowering taste at the front. The aftertaste is pleasant with similarities to a sweet white wine. The low acidity has more of a smooth feel on the mouth, contrasting with the more carbonated and chemical bite of something like a sugar free Monster Zero. The energy kick is more akin to a coffee buzz. Overall I would rate Sugar Free Red Bull a 4.5 out of 5.

[This review was collected as part of a promotion.] The Red Bull Zero Energy drink had a good tangy flavor and did not taste overly artificial. There is no nasty aftertaste, however I was left with a dry mouth. Additionally, the drink got stale super quickly and was not as refreshing as expected after being refrigerated for several days.

[This review was collected as part of a promotion.] Was very good and very effective in giving me energy! The ingredients were not harmful and were easy to understand. To to mention the taste was great! For the size you got so much for the oz that it came in there was so much value in the package. I would recommend.

[This review was collected as part of a promotion.] Closer to the original red bull flavor but tastes quite flat - i like it more carbonated. Not too sure what the target market is since there already original and sugar free - but it still tastes good

[This review was collected as part of a promotion.] I liked this Red Bull energy drink pretty good. I liked that it had monk fruit extract but I didn’t like that it also contains sucralose and erythritol. The taste is pretty good but I won’t buy this drink again because I don’t like that it has sucralose which is an artificial sweetener added to it. The energy drink seemed to work as well for keeping me awake and alert as much as any other energy drink has.

[This review was collected as part of a promotion.] I enjoyed this drink- I like that it had no sugar, but the flavor was lacking compared to the original Red Bulls. The can was a perfect size easy to hold and pack into lunch box. Also lip of the can is easy to drink out of.

[This review was collected as part of a promotion.] Red Bull zero is pretty much a diluted regular Red Bull , I would say water down, it’s not a bad option if you’re trying to cut down calories intake a 250 ml can only has 5 calories, and most important 0 added sugar, it does have a different after taste but it’s not bad at all.

[This review was collected as part of a promotion.] I don’t usually like any Red Bull flavor that is sugar-free but this one is definitely an exception. The after taste is a little odd, but this was the only Red Bull (no sugar) L drink I was able to finally finish!

[This review was collected as part of a promotion.] This tastes like a normal Redbull. I didn’t find the flavor profile to be strong enough to really taste and enjoy. It’s effectiveness was just like a normal Redbull as well. The color of the packaging is lovely though.

[This review was collected as part of a promotion.] Smoother and slightly less sharp than regular Red Bull, with monk fruit giving a light natural sweetness. Less of the “artificial” aftertaste you sometimes get in sugar-free energy drinks. Sleek silver and blue design with a modern, clean look; easy to hold and carry.
