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 ZONe COLD SLEEP

When you open the can, the lychee aroma bursts out. The liquid itself has a slight yellowish tint.

Upon tasting, the mellow sweetness of lychee and the bitterness of grapefruit spread across your palate. This ZONe COLD SLEEP contains 18% fruit juice, and it seems to include both grapefruit and lychee.

The base flavor is lychee, with a subtle aftertaste of grapefruit's bitter flavor, which lingers for a while. This grapefruit flavor refreshingly transforms the sweet lychee, creating a cooling sensation.

Though the combination is a bit unusual, both flavors capture their distinct characteristics, and you can fully enjoy the deliciousness of both lychee and grapefruit without the taste becoming muddled.

While the frozen can design might suggest a menthol-like coolness or a chilly sensation, there's none of that here. The combination of lychee and grapefruit is surprisingly refreshing, with little aftertaste and no lingering sweetness.

Though it's not an overly rich or dense fruit flavor, the taste itself is actually quite strong, and even with ice added, the flavor doesn't weaken. The fruity aroma still wafts through, making it a satisfying drink. This must be thanks to the 18% fruit juice and high carbohydrate content.

Even when chilled, it’s delicious, and when you load it with ice, you can enjoy the lychee and grapefruit flavors without losing any of their taste. It’s truly a summer-ready energy drink.

Energy Ingredients of ZONe COLD SLEEP

ZONe COLD SLEEP
Contains 75mg of caffeine and 500mg of arginine. It also contains 5g of slowly absorbed palatinose in its carbohydrates.

The caffeine content is moderate for a 500ml drink, but since this version, like others in the ZONe series, is high in carbohydrates, it might be something to be mindful of.

Design of ZONe COLD SLEEP

The standout feature is this bold, frozen, icy design. It has a huge impact compared to other drinks in the ZONe series! It's the kind of packaging design that makes you want to pick it up in the summer.

Inside the transparent can, the ZONe logo appears as if it’s actually frozen, giving a rather realistic vibe.

The name "Cold Sleep" may be inspired by the cryogenic sleep used in space movies to preserve life during long-distance travel.

The version number "-1.9.6" evokes the chilling temperature of -196°C, hinting at the idea of instant-freezing fruits, adding a playful touch to the design.

The back of the can says "Dive into the ZONe," with an illustration of entering the zone, heading from 0°C down to -196°C.

ZONe COLD SLEEP, with its exceptional design that evokes the feeling of instant freezing, is a refreshing and satisfying drink. Why not try the lychee and grapefruit flavors this summer?
