REIGN MELON MANIA, a watermelon-flavored energy drink from the high-caffeine fitness-oriented REIGN brand, was born in the United States in 2019.

Watermelon has now become a standard flavor in the energy drink industry, but how has the zero-calorie, zero-sugar REIGN version turned out!?

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 8,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Sweet, Artificial Watermelon Candy Flavor

When opened, the sweet smell of watermelon is quite strong. It’s like a more intense version of the "Suika Bar" ice cream. Despite the strong and sweet watermelon scent, the liquid is colorless and transparent when poured into a glass. The strong fragrance creates a sense of surprise as the transparent liquid seems unexpectedly subtle.

Upon tasting, you get a gentle sweetness with a watermelon candy flavor. There’s no refreshing or savory taste of real watermelon flesh, just an artificial taste.

After drinking, there’s a lingering aftertaste, with faint notes of artificial sweeteners, but overall, the watermelon flavor reaches a pretty good level.

Since the flavor and aroma are both strong, if you expect a refreshing, light taste due to the zero-calorie, zero-sugar nature of the drink, the bold sweetness might come as a surprise.

Many foreign watermelon-flavored energy drinks have a greenish, melon-like odor, but REIGN MELON MANIA lacks this, so it presents a watermelon flavor that Japanese drinkers can enjoy, just as expected.

That said, the sweet watermelon flavor persists throughout, so honestly, you might get a bit tired of it midway. Adding plenty of ice is recommended for a more refreshing experience.

Energy Ingredients of REIGN MELON MANIA

REIGN MELON MANIA
It contains 300mg of caffeine, BCAAs, and CoQ10. It’s one of the top caffeine levels found in North American energy drinks. With almost double the caffeine (150-160mg) of the usual 473ml energy drinks in North America, it’s important to be careful not to overconsume. The exact amounts of BCAAs and CoQ10 are unknown, so it’s likely in trace amounts.

Design of REIGN MELON MANIA

The can features a textured surface for a tactile experience, with a REIGN logo in green and red that evokes watermelon.
