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 28 BLACK SOUR MANGO-KIWI

Opening the can, a refreshing tropical fruit scent bursts out. It's not quite the scent of real fruit, but the anticipation rises.

Let’s take a sip. The first impression is a tropical fruit mix leaning toward exotic flavors commonly found in Europe, with the sourness of papaya, pineapple, and passion fruit. Neither the mango nor the kiwi brings sweetness or rich flavor, with the taste leaning entirely into sourness.

Sour Mango-Kiwi is now available in Japan, making it easy to enjoy.

Even with ice added, the exotic sour flavor is still strong. Drin-kun loves the Sour Mango-Kiwi with ice (*´艸｀*)

Energy Ingredients of 28 BLACK SOUR MANGO-KIWI

No taurine, vegan, gluten-free, lactose-free. The packaging has changed to a simpler label compared to the previous version. It’s better this way without too much emphasis. In the past, the packaging felt a bit cluttered.

Increased Color Variations and the New Design Has Improved

28 BLACK revamped its design in 2017. I initially thought the simple, single-color design was cooler, but as they expanded their flavor options, the color variations improved the overall appearance.

As expected, expanding the range of colors and releasing limited edition products with more intricate designs helps build the brand across the entire line, which is a unique trait of energy drinks.

The tab is silver. With the increasing variety of colors and flavors, it’ll be interesting to see if they switch to different color tabs for each or unify with black tabs in the future.
