A 'Tuned Up Taste': The 2006 Reformulation
Before 2006, the low-calorie citrus soda was sweetened exclusively with aspartame. The change occurred as part of a brand-wide initiative by PepsiCo to create a "Tuned Up Taste" for Diet Mountain Dew. The new formula, implemented in 2006, combined a trio of artificial sweeteners: sucralose, acesulfame potassium (Ace-K), and aspartame. This blended approach was designed to create a more complex and satisfying flavor profile that could better mimic the taste of sugar than aspartame alone. The move aligned with a broader industry trend of using multiple artificial sweeteners to achieve synergistic flavor effects.
Sweetener Changes in Popular Diet Sodas
Diet soda formulations have frequently evolved over the years as companies seek to refine their products and respond to changing consumer tastes. The addition of sucralose to Diet Mountain Dew was not an isolated incident but rather part of a larger trend in the beverage industry.
- Diet Pepsi: While Diet Pepsi has also seen sweetener changes, its journey is a bit more complex. In 2015, PepsiCo shifted Diet Pepsi's sweetener blend in the US, moving from aspartame to a sucralose and Ace-K blend. However, sales declined, and the company eventually brought back an aspartame-sweetened version in 2018.
- Coke Zero: Introduced in 2005, Coke Zero was specifically marketed to taste more like classic Coca-Cola, with its own blended sweetener formula.
- Diet Sprite: The Coca-Cola Company also tinkered with the sweetener blend for Diet Sprite, making changes around the year 2000.
These changes illustrate the ongoing quest for the perfect combination of flavor, cost, and consumer preference in the diet beverage market. The 2006 sucralose addition for Diet Mountain Dew was PepsiCo's attempt to lead this charge for one of its key brands.
Consumer Response and Legacy of the New Formula
The 2006 formula change to include sucralose generated considerable discussion among loyal Diet Mountain Dew drinkers. Some fans of the older, aspartame-only version noticed a change in taste, while others appreciated the new complexity. The debate over which formula was superior highlights the passionate fan base that Mountain Dew has cultivated over the years.
The most significant legacy of the 2006 reformulation, however, was the introduction of a new, low-sugar alternative in 2020: Mountain Dew Zero Sugar. The addition of sucralose to Diet Mountain Dew allowed PepsiCo to explore a different taste profile with the Zero Sugar line, which also uses a similar blend of sucralose and Ace-K. A key difference is that PepsiCo's representatives confirmed that the release of Zero Sugar would not replace Diet Mountain Dew, instead opting for both products to coexist in the US market. This offers consumers a choice between two different zero-calorie Mountain Dew experiences, catering to different flavor preferences.

Conclusion: The Long-Term Impact
To summarize, Diet Mountain Dew added sucralose in 2006 as part of a significant reformulation aimed at creating a "Tuned Up Taste". This change replaced the previous aspartame-only formula with a blend of sucralose, acesulfame potassium, and aspartame. The move was a strategic decision by PepsiCo to innovate within the low-calorie beverage space, aligning with broader industry trends. While the change sparked debate among consumers, it ultimately led to a more diverse product line and provided the company with valuable data on consumer preferences for different sweetener blends. The current coexistence of Diet Mountain Dew and Mountain Dew Zero Sugar demonstrates the lasting impact of this sweetener evolution.
