Introduction

Monster Ultra Blue is a decent energy drink. Most of the Monster Ultras are incredible, but this one is just average. The energy blend is the same as the other Ultras, so the mouth feel and aftertaste are fantastic. The blue raspberry flavor just does not do it for me. I love most blue beverages, but the raspberry is not ideal. The kick is also lower than most other energy drinks because it only has 140mg of caffeine (8.75mg/floz) per can.

Upside

The upside is that it is a Monster Ultra. This means the mouth feel and general sweet aftertaste are phenomenal. If I were judging drinks exclusively by these categories, it would be a 9+/10. The can also looks pretty cool. I like how the silver, black, and blue look integrated. This is one of my favorite Monster Ultra cans when really looking closely.

Downside

The kick is terrible. 140mg will not do much to people with a caffeine tolerance. I recently got one to watch during the Thursday night football game, and kept almost falling asleep. That may say more about my caffeine habits than the drink itself, but the point still stands. The blue raspberry flavor is not my favorite. It tastes decent and is very smooth, but I was expecting more from a blue Monster Ultra.

Upshot

Monster Ultra Blue is smooth and sweet like all Monster Ultras, but the kick and flavor leave something to be desired. While it is an enjoyable beverage, the low caffeine content and raspberry taste are not what I am looking for in an energy drink. This review may seem negative for a beverage rated 6.8/10 overall; I was just expecting more from it. Monster Ultra Blue is not bad by any means, I just would not go out of my way to have another.

Appearance

Ultra Blue is just another example of the tried and true packaging formula from Monster’s Ultra Zero line. The unique touches for this version include some subtle snowflakes and hidden Monster logos in the chrome graphics flanking the center of the can. Overall, another excellent can from Monster.

Taste

This is another consistent entry from Monster. It feels like every Ultra Zero based Monster sticks to the formula. This drink is no exception, tasting like the Ultra Zero with just enough added flavoring to give Ultra Blue a distinct flavor. Ultra Blue pushes a frost theme and I’d argue that it tastes accordingly, although it’s difficult to describe. It’s fairly delicious, but does not do anything different than most zero sugar Monster drinks.

Kick

I am not sure if the additional ingredients that Monster markets as providing energy work, but in this case I felt a strong reaction. 150mg of caffeine isn’t nothing, but definitely falls short of the growing list of energy drinks touting 300mg in each can. Nonetheless, Ultra Blue makes a strong case for not needing an exorbitant amount of caffeine in each can.

Overall

If you enjoy Monster’s formulaic set of zero sugar energy drinks, Ultra Blue will not disappoint. I haven’t found one that I have disliked. That being said, I find that a majority of the zero sugar drinks are almost too similar and don’t taste that much different. Ultra Blue falls into that category. I’d place it somewhere in the middle of Monster’s zero sugar lineup, which is collectively above average when compared to all other energy drinks.
