C4 ENERGY JOLLY RANCHER WATERMELON

Posted on July 18, 2025 | Last updated January 20, 2026

C4 ENERGY JOLLY RANCHER WATERMELON
Released in September 2024. A collaboration series between C4 ENERGY and the American candy brand "JOLLY RANCHER" launched simultaneously with three flavors.

This time, I am reviewing one of them: "C4 ENERGY JOLLY RANCHER WATERMELON".

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.

Flavor of C4 ENERGY JOLLY RANCHER WATERMELON

Upon opening the can, a sterile aroma spreads, reminiscent of apple, pear, and peach, without any sweetness, acidity, or fruity character. It is a distinctive scent that makes me think, "What flavor is this?" due to its lack of umami. Let me take a sip.
Flavor of C4 ENERGY JOLLY RANCHER WATERMELON
On the palate, just as suggested by the aroma, there is no sweetness and only a faint acidity, with a flavor reminiscent of apple or peach stripped of its umami. What flavor was this again? I checked the package and saw: watermelon flavor. I see, this bland, hollow taste must be the flavor of watermelon rind.

The flavor of watermelon flesh is extremely weak, and it feels like drinking watermelon rind with neither sweetness nor acidity.

There is none of the green, cucumber-like aroma or flavor commonly associated with other watermelon flavors, and if this is considered a watermelon rind flavor, the level of completion is relatively high.

That said, it lacks umami and any sense of freshness, and remains a "washed-out flavor" throughout, making it extremely difficult to enjoyably finish the entire 473 ml. Frankly, it is a stretch.

Put kindly, it is "a flavor you do not need to drink"; put bluntly, it is "not tasty".

The smooth surface finish is a common specification shared by C4 ENERGY collaboration products with other brands.

The design combines C4’s brand color yellow with a pale pink used as the flavor color, and the JOLLY RANCHER logo is placed at the top of the can.

Along the side of the can, a lineup of watermelon-flavored JOLLY RANCHER candies appears, a standard design used for collaborations.

Collaborations with long-established, widely recognized brands like JOLLY RANCHER are one effective strategy for making C4 ENERGY feel more approachable.

Considering its evolution from a supplement manufacturer into an energy drink brand recognized by a broader audience, I expect collaborations with well-known brands to continue in the future.
