In 2001, while living in the United States, I encountered energy drinks through the dance scene and was deeply impressed. After returning to Japan, I found that energy drinks were considered novelty beverages, so I established a comprehensive website in 2013 to share the true appeal of energy drinks. As an energy drink enthusiast, I began drinking them seriously again, collecting over 7,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Flavor of MONSTER ENERGY ULTRA PEACHY KEEN

Upon opening the can, a sweet peach fragrance bursts out. The liquid is a yellow color reminiscent of ripe peach flesh. Let’s try the zero-sugar peach flavor right away.

When I take a sip, I’m greeted with a smooth, mildly tangy peach flavor. The refreshing peach aroma lingers in the mouth, providing a satisfying experience. At first, it doesn’t feel like a zero-sugar drink at all—it's a fruity flavor with a high level of perfection.

As I continue drinking, the flavor and aroma become more familiar, and it settles into a slightly flat, sweet peach taste. However, there’s no cheap, artificial sweetness or unpleasant aftertaste from artificial sweeteners. In fact, it’s hard to believe this is a zero-calorie drink.

It’s rare for a zero-sugar drink to taste good at room temperature, but this one does. It’s also great when chilled, and adding ice further enhances the refreshing taste. I was surprised that the peach sweetness remains even after adding ice.

There’s also a sales sample of MONSTER ENERGY ULTRA PEACHY KEEN before its official release, so I decided to compare it.

The contents are exactly the same. The nutritional information and design are also identical to the final product, meaning there were no changes before its official release.

After drinking both the product and the sample, I never got bored of the peach’s well-balanced flavor and refreshing taste. Additionally, the lack of any unpleasant artificial sweetener aftertaste is what makes this zero-sugar product stand out. If you ever get the chance to visit the United States, definitely give this a try—it’s a perfect drink for the summer season there.

Energy Ingredients of MONSTER ENERGY ULTRA PEACHY KEEN

It contains 150mg of caffeine, taurine, carnitine, and inositol as part of the Monster Energy blend.

The Ultra series is zero-sugar, which is great because you can enjoy such a high-quality flavor without worrying about extra sugar intake. The Ultra series always delivers.

Design of MONSTER ENERGY ULTRA PEACHY KEEN

The gentle pink color makes it easy to associate with the peach flavor, and the product name “PEACHY KEEN” also conveys the idea of “the best peach flavor,” which is simple and clear.

The design is packed with 1960s hippie culture, including references to Haight-Ashbury, the Magic Bus, Love and Peace, and much more. It’s all packed in there.

The distinctive rough surface finish of the Ultra series, combined with the white outline and hippie-style design, creates a unique atmosphere. One of the best parts of Monster Energy drinks is being able to enjoy the can design while drinking.
