Diet Mountain Dew

Diet Mountain Dew (also known in several countries as "All Dew, No Sugar") is a Mountain Dew variant with only ten calories, compared to the 290 calories in the original, and is sweetened with artificial sweeteners instead of Corn Syrup or Sugar.


Diet Mountain Dew is a modified version of the original formula, containing low sugar count but retaining the same citrus taste and yellow-green color as the original Mountain Dew drink, similar to, but a separate drink from, Mountain Dew Zero Sugar.


Its tagline is "Low Calorie DEW."


Diet Mountain Dew was first introduced alongside Caffeine-Free Mountain Dew in 1976 in response to the growing trend in America of weight-watching. It used to be branded as Sugar-Free Mountain Dew until 1984 when it was renamed to Diet Mountain Dew, its current name.

In 2006, Diet Mountain Dew received a formula change by PepsiCo created a new and improved formula called a "Tuned Up Taste." This "Tuned Up Taste" uses a blend of sweeteners named sucralose, aspartame, and acesulfame potassium. The previous formulation was sweetened exclusively with aspartame.

Starting in January 2020, Mountain Dew Zero Sugar was released in the United States. Before its introduction, people were worried that it would replace Diet Mountain Dew as the new low sugar drink in the United States. It was confirmed by a PepsiCo employee that there weren't any plans for Zero Sugar to replace Diet Mountain Dew. Instead, it will coexist with it. As of June 2022, Diet and Zero Sugar are still available for Americans to enjoy.

International release


At some point during the 1990s, Diet Mountain Dew was getting sold in Canada. This version was sold without caffeine due to laws preventing caffeine from being added to non-dark soft drinks.

It is unknown when it was discontinued, but it returned in 2012 as Diet Mountain Dew Citrus Charge, to match the Citrus Charge branding shift when laws changed and Mountain Dew added caffeine like in other countries.

In 2017, the Diet Mountain Dew Citrus Charge was rebranded and received similar packing to its American counterpart, dropping the "Citrus Charge" label and becoming known simply as Diet Mountain Dew in English (Mountain Dew Diète in French).

At the start of April 2020, following the American release of Mountain Dew Zero Sugar in January 2020, Mountain Dew Zero Sugar replaced Diet Mountain Dew rather than (unlike in the United States) coexisting with Diet. It was only released in 12 packs.

However, from 2022 onward, Diet Mountain Dew coexists with Mountain Dew Zero Sugar in Newfoundland, and other eastern provinces, making it a region-specific flavor.

In the United Kingdom, the Original Dew was first sold in 1997 alongside the standard variety under the Diet Mountain Dew name before being pulled from the market in 1998 due to low sales.
