The ‘Rarest’ Mountain Dew Flavor Doesn’t Actually Exist

If you love Mountain Dew, odds are you’ve got a specific flavor beyond the original that you can’t get enough of. Maybe it’s the iconic Baja Blast or the hard-to-find Maui Burst. I’m personally a Code Red kind of girl, even though it’s not exactly a rarity. But while the most hardcore Mountain Dew fans might think they’ve tried just about every iteration of the iconic soda, there’s one only a select few have tried—or even seen in person. Neon Night. The only problem? The flavor never actually existed.

Sporked discovered a claim that the rarest Mountain Dew flavor is none other than the mystery Neon Night. Naturally, we had to look into this legend of a flavor no one had heard of.

The Mysterious Flavor That Never Hit Stores?

In 2010, a number of fresh spins on Mountain Dew were released, including a range of colors well beyond that iconic glowing green. The uniquely-hued and citrus-flavored White Out (which, true to its name, was actually white), for example, and Typhoon Dew, a tropical punch-inspired flavor that had a pink-orange hue, splashed onto store shelves. 

Google’s gen-AI Gemini, which now powers the People Also Ask section, states that another Mountain Dew flavor popped up that same year, but was never released. The ‘legend’ states that prototypes of the soda spinoff were made—but this Mountain Dew variety never made it any further. And that, for the most part, it’s disappeared into Dew history. Only ‘serious collectors’ know of its existence because only 17 prototype cans were ever made. At some point, the flavor was shelved altogether and never reached production, so Neon Night never hit retailers (or even Taco Bell locations, where Mountain Dew reigns supreme).

So the rumor here is that a flavor called Neon Night was developed and produced for internal focus groups, with specifically 17 cans created, but never released to the public. But there’s no proof that the soda ever actually existed. Not a single collector comment, not a Reddit thread, not an old eBay auction for a rare can—nothing. The only mention of Neon Night comes from Google’s own Gemini.

The Facts

It’s not unheard of that a Mountain Dew flavor would be dreamed up, concocted and produced, and then suddenly shelved. It’s happened plenty of times, in fact―there are numerous never-released flavors we’ve long wished we could’ve tasted (although I’m personally kind of glad that Mountain Dew ultimately cancelled the Doritos Nacho Cheese-inspired DEWitos flavor, which sounds slightly horrifying). And some flavors do manage to make it into production, only to be yanked off shelves after trial runs and summarily discontinued for good. 

But the origin of the Neon Night flavor starts and ends with Gemini.

From industry leaks and rumors to limited-edition cans, Dew fans know what they’re talking about. So it’s especially strange that no one seems to have ever heard of Neon Night, even 16 years later. There’s no proof that those 17 cans ever existed or that Mountain Dew ever even considered the name for a release.

So as far as tasting this incredibly ‘rare’ Mountain Dew flavor? Well, don’t get your hopes up.
