Core Ingredients of Mountain Dew
At its heart, Mountain Dew's distinct flavor and characteristics come from a specific blend of core components. The standard formula relies on a few key players to create its signature taste and appearance.
- Carbonated Water: The foundational ingredient of any soda, carbonated water provides the fizz and bubbles that give Mountain Dew its classic effervescence.
- High Fructose Corn Syrup (HFCS): In the United States, HFCS is the primary sweetener used in Mountain Dew, providing the drink's intense sweetness. The use of this ingredient has made some consumers opt for the limited-edition 'Real Sugar' version, which uses cane sugar instead.
- Concentrated Orange Juice: A small amount of concentrated orange juice is included in the formula. This addition is what distinguishes Mountain Dew from a typical lemon-lime soda and contributes to its unique citrusy flavor profile.
- Citric Acid: As a flavoring agent and a preservative, citric acid gives the soda its tangy, tart taste and helps maintain its shelf stability.
- Natural Flavor: This is a proprietary ingredient that PepsiCo does not fully disclose. It is the complex mixture of chemicals that creates Mountain Dew's specific and instantly recognizable citrus taste.
- Caffeine: A 12-ounce can of Mountain Dew contains a significant amount of caffeine, more than a comparable serving of many other popular sodas, contributing to its reputation as an energy-boosting beverage.
Additives and Preservatives in the Recipe
Beyond the core taste components, several other ingredients are used to preserve, stabilize, and color the soda. These are crucial for maintaining the product's consistency and appearance over time.
- Preservatives: Sodium benzoate and erythorbic acid are included to preserve freshness and prevent spoilage.
- Gum Arabic: This is a stabilizer that helps to keep the ingredients uniformly mixed throughout the beverage.
- Calcium Disodium EDTA: An ingredient used to protect the flavor and prevent degradation.
- Yellow 5: This artificial food coloring, also known as Tartrazine, is responsible for Mountain Dew's iconic neon green-yellow color.
Formula Changes Over Time
Mountain Dew's formula has not remained static since its creation. Notable changes have occurred over the decades, often in response to consumer feedback or regulatory concerns.
- Brominated Vegetable Oil (BVO): Previously used as an emulsifier, BVO was removed from Mountain Dew in 2020 after growing concerns about its safety. The ingredient is banned in some countries, including Europe and Japan.
- Sweetener Variations: While HFCS is the standard in the U.S., other sweeteners are used in international markets. Some variations of Mountain Dew, like the limited-edition 'Real Sugar' version, use cane sugar.
- Artificial Sweeteners: PepsiCo has also introduced other variations like Diet Mountain Dew and Zero Sugar Mountain Dew, which use artificial sweeteners such as aspartame and sucralose instead of sugar or HFCS.

Conclusion: More Than Just a Soda
Understanding what is Mountain Dew made of reveals that the iconic citrus soda is a complex blend of core ingredients, preservatives, and colorants designed to create a specific flavor and visual appeal. From the carbonated water and orange juice concentrate that define its taste to the high fructose corn syrup and caffeine that provide its signature kick, each ingredient plays a critical role. While the formula has evolved over time, especially with the removal of ingredients like BVO, the end result remains one of the most recognizable and widely consumed sodas on the market.
