The 90s were a wild time for soda lovers, with brands constantly pushing the limits of flavor, color, and marketing gimmicks. From neon-colored drinks to bizarre ingredient combinations, every new release felt like an experiment in what kids and teens would dare to try. Some of these sodas became instant classics, while others disappeared almost as quickly as they arrived—but they all left a lasting impression on those who were brave enough to take a sip.
Vault

Vault was Coca-Cola’s hybrid between an energy drink and a soda, boasting high caffeine content and a citrusy taste. Marketed as “drinks like a soda, kicks like an energy drink,” it gained a cult following before being discontinued. Many fans still mourn its loss.
Coca-Cola Black Cherry Vanilla

This soda combined two classic flavors black cherry and vanilla for a smooth and rich taste. While some loved the unique blend, others felt it was too far removed from regular Coke. It didn’t last long, but similar flavors have popped up since and.
Mello Yello Melon

Mello Yello was already a beloved citrus soda, but the melon version took things in a sweeter direction. It had a candy-like taste that some adored, while others found it too artificial. Like many of these experimental flavors, it quietly disappeared.
Mountain Dew Pitch Black

Originally released as a limited-edition Halloween flavor, this dark purple soda had a bold grape taste. Its popularity led to several revivals, but it never quite secured a permanent spot in the lineup. Fans still reminisce about its tart and tangy kick.
Dr Pepper Red Fusion

Dr Pepper is known for its unique taste, but Red Fusion amped things up with an extra fruity kick. The cherry-forward flavor was polarizing some loved it, while others preferred regular Dr Pepper. It quietly disappeared, becoming a forgotten experiment.
OK Soda

Aimed at cynical Gen X teens, OK Soda featured abstract marketing and a deliberately vague name. Instead of a traditional ad campaign, it leaned into ironic messaging and moody black-and-white cans. The flavor—a mix of citrus and spice—wasn’t bad, but the marketing was just too strange for mainstream appeal.

Crystal Pepsi

Pepsi shocked the world by releasing a completely clear version of its iconic soda, promising the same great taste without the caramel coloring. While the novelty intrigued consumers, many found it too similar to regular Pepsi to justify its existence. After a brief comeback in recent years, it still remains more of a nostalgic relic than a permanent fixture.

Slice

Before Sierra Mist, Pepsi had Slice a fruit-flavored soda line that included orange, grape, and lemon-lime varieties. It was a staple in the 90s but was eventually replaced by newer brands. Some nostalgic fans still miss its bright, juicy flavors.

Fruitopia

A Coca-Cola brand meant to compete with Snapple, Fruitopia was a fruit-flavored soda packed with New Age-style branding. Popular in schools and vending machines, flavors like Strawberry Passion Awareness won over kids and teens. Despite its initial success, it was later absorbed into the Minute Maid brand and disappeared.

Dr Pepper Berries & Cream

Dr Pepper already has a distinct taste, but adding berries and cream took it in a whole new direction. Some loved the smooth, fruity twist, while others thought it was an unnecessary change. It had a brief return in 2022 but is no longer widely available.
