(CNN)It looks like Four Loko is joining the crowded hard seltzer market.
The brand behind the colorful cans of high-alcohol malt beverages tweeted a photo Tuesday night of Four Loko Seltzer Sour, a seltzer subtly infused "with a hint of blue razz."
The can touts it as the "hardest seltzer in the universe," which it very well may be: The drink contains 14% alcohol by volume, nearly three times as much as leading alcoholic seltzers like White Claw.
It joins a lineup of unnaturally neon-hued gas station favorites like Watermelon, Sour Apple and Gold -- which, according to the website, tastes like gold?
Four Loko's parent company, Phusion Projects, didn't respond to a request for comment or share a release date for the seltzer, so those searching for a more hardcore fizzy water will have to wait.
Hard seltzer sales are skyrocketing
Whether a Four Loko seltzer should exist is one thing, but it's probably a shrewd business decision: Spiked seltzers are having a major moment.
White Claw's sales accounted for nearly 55% of all hard seltzer sales for the week of July 4, a 200% increase since 2018's Fourth of July sales, according to data from Nielsen.
Together, White Claw and Truly, the second-largest seltzer brand, dominate nearly 85% of spiked seltzer sales, which have grown almost 200% across the market since last year, Nielsen reported.
The low-calorie, low-sugar drinks are often advertised as a healthier alternative to beer, though they pack a similar alcohol content, usually around 5% ABV.
It's unclear how long the reign of spiked seltzers will last, but let's hope it's enough to find out whether Four Loko's "blue razz" version is neon blue.
