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.

The Intense Crazy Green of Beast Eye is Tempting

The can design of Beast Eye is a bit unclear... Is it a cat? It doesn’t really feel like an energy drink. It gives off an impression similar to the crocodile from Mad Croc.

The contents are, as expected, an incredibly green color. When it’s this vibrant, it really lifts your spirits ((o(´∀｀)o)). The cat's eyes on the can are red, but I think green would have suited it better. The newly released Sapphire has blue eyes and blue liquid, so perhaps when this was developed, there weren’t plans for a second version. The red eyes seem a bit wasted.

The Taste of Beast Eye...

I had an inkling from the scent, but when I tried it, it tasted just like Lotte’s plum gum that used to come in pink packaging. After a quick search, I found someone else saying that Beast Eye tastes like nostalgic plum gum. It gives off a distinct "cheap candy" vibe, but if I say “plum gum,” you probably know exactly what I mean. I used to love it. Coffee gum or plum gum always felt like a separate category of snacks, and I ate them quite often.

It has a plum gum flavor, but there's also a hint of a dangerous chemical taste from the coloring and sweeteners, reminiscent of the type of flavor you’d find in old-school Japanese candy shops.

The Coloring of Beast Eye is Intense

The ingredients list mentions colorants (Yellow 4, Blue 1). I won’t bother checking the exact contents, but this combination is what gives the drink its iconic green color. When poured into a glass, it looks incredibly beautiful. The green hue contrasts perfectly with the glass’s edge. One of the fun parts of energy drinks is enjoying the vivid colors visually.

However, when it splashes onto the white can due to carbonation, it’s no longer green at all, haha. It ends up looking like the color of some dangerous paint or spray. By the way, the carbonation isn’t particularly strong, but the bubbles pop really energetically. You’ll probably make a mess on the table, so be careful when pouring!

The Energy Ingredients of Beast Eye

The energy components are a bit weaker compared to typical energy drinks. It seems to have less than 40mg of caffeine, but surprisingly it has 33mg of carbohydrates. The sugar content is pretty high. Considering the recent trend of increasing caffeine levels, the ingredients might feel a bit lacking, but given Beast Eye’s color and plum gum flavor, I guess it doesn’t really matter.

If you want a noticeable wake-up effect from your energy drink, you might prefer something like Monster or a 160mg caffeine drink, but even with that amount, it’s likely more of a placebo effect. So, you can always use the "green magic juice" to lift your spirits (*´艸｀*).
