Relentless DEVOTION 50% JUICE BERRY FLAVOR
This is a berry-flavored Relentless energy drink released in 2009, featuring 50% fruit juice. Later, the product was given the name "DEVOTION," so I will review it here as DEVOTION 50% Juice.

This is a rare can from the 2009 gold-top release. Let’s enjoy the rich berry juice flavor.

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.

Tangy and Slightly Astringent Cranberry & Raspberry Mix Flavor

The moment I opened the can, I was greeted by a rich, juicy red berry aroma, along with a deep, dark red liquid reminiscent of cherry cola—what an exciting sight! The contents perfectly match the can’s intense red design, making for a fantastic first impression.

Taking a sip, I was met with a tangy-sweet raspberry flavor, complemented by a natural astringency that adds depth, delivering a luxurious high-juice berry experience. The astringency, in particular, serves as a great accent, setting it apart from typical sweet-and-sour berry flavors by recreating the complex, fresh-squeezed essence of real fruit.

Despite containing 50% juice, it doesn’t feel overly heavy or thick, maintaining an easy-drinking quality that makes the 500ml can surprisingly manageable. I think the balance is achieved by keeping the aroma restrained enough not to overpower the taste.

Even considering potential aging effects, there's no doubt that this is an exceptionally well-crafted raspberry flavor.

The deep red can is densely covered with illustrations of lush foliage, accompanied by various berries. Interestingly, there's even a fly depicted—an unusual choice for a food or beverage product! (^_^;)

Looking at the design evolution, when the product was rebranded as "DEVOTION," it adopted a mythological-themed aesthetic. This design was later carried over to the subsequent release of Relentless DEVOTION 20% JUICE BERRY.
