Overview
Sierra Mist was a lemon-lime flavored carbonated soft-drink brand created by PepsiCo for the United States market. Introduced in 1999, it was developed to compete with established lemon-lime sodas such as Coca-Cola's Sprite and 7 Up. The name combined imagery associated with mountains and water droplets: "sierra" refers to a mountain range in Spanish, while both mist and dew describe fine water droplets, creating an indirect thematic connection with PepsiCo's Mountain Dew brand. The drink expanded nationally over its early years and was available throughout the United States by 2003. Its history was marked by repeated changes to its formula, sweeteners, naming, and marketing. The original formulation used different combinations of sugar and high-fructose corn syrup over time. In 2010, PepsiCo introduced Sierra Mist Natural, which replaced high-fructose corn syrup with sucrose and presented the product as a more natural alternative. By 2013, the shorter Sierra Mist name had returned, and in 2014 PepsiCo changed the sweetener system again by combining sucrose with stevia in an effort to reduce calories. Consumer criticism reportedly focused on the aftertaste associated with stevia. PepsiCo announced another substantial brand change in late 2015. During 2016, Sierra Mist was renamed Mist Twst in some markets, and the formula again included high-fructose corn syrup. The Mist Twst identity was short-lived: the brand returned to the Sierra Mist name in 2018. These changes reflected the competitive pressure facing mainstream carbonated soft drinks, including demand for different sweetener profiles, lower-calorie choices, and clearer product positioning. Marketing was a significant part of the brand's identity. Its "Mist Takes" campaign used improv-oriented comedy and featured performers including Nicole Sullivan, Debra Wilson, Aries Spears, Jim Gaffigan, Michael Ian Black, Kathy Griffin, Tracy Morgan, and Guillermo Diaz. Spanish-language versions included performers associated with the Mexican television program Otro Rollo. Sierra Mist also supported entertainment and sports properties, including a limited-time Undercover Orange product connected with the 2007 Warner Bros. film Get Smart. In sports, the brand served as an official partner and sponsor of Major League Soccer and sponsored the New England Revolution and D.C. United until the league's beverage partnership changed in 2015. PepsiCo discontinued Sierra Mist in January 2023 and replaced it with Starry, a new lemon-lime soft-drink brand. Sierra Mist is therefore a defunct product brand rather than an active PepsiCo offering. Its importance within PepsiCo's beverage portfolio lies in its long-running attempt to establish a distinct challenger to Sprite and 7 Up through national distribution, formula experimentation, comedy-led advertising, sports sponsorship, and successive rebrandings.
History
PepsiCo introduced Sierra Mist in 1999 as a United States lemon-lime soft drink positioned against Sprite and 7 Up. The brand name used mountain and water imagery: "sierra" means mountain range in Spanish, while mist and dew refer to water droplets. This naming also created a loose conceptual relationship with PepsiCo's Mountain Dew, although Sierra Mist occupied the lemon-lime segment rather than Mountain Dew's citrus-caffeine positioning. The brand achieved national distribution during its early development and was available in all United States markets by 2003. Its original formulation changed over time. Between 2000 and 2006, it used combinations of high-fructose corn syrup and sugar; from 2006 through 2010, high-fructose corn syrup was the stated sweetener. Diet Sierra Mist used aspartame and acesulfame potassium. In August 2010, PepsiCo introduced Sierra Mist Natural, replacing the earlier formula with one based on sucrose and presenting a shorter ingredient list. The product subsequently returned to the simpler Sierra Mist name by 2013. In 2014, PepsiCo altered the formula again by combining sucrose and stevia to lower calories. The stevia formulation generated negative consumer reactions associated with an unpleasant aftertaste. PepsiCo then pursued a broader identity change. In December 2015, it announced that Sierra Mist would become Mist Twst, a change implemented in some markets during 2016. The renamed product also restored high-fructose corn syrup to the formula. In July 2018, the company reversed the naming decision and restored Sierra Mist. Promotion relied heavily on comedy and cultural partnerships. The 2005 "Mist Takes" advertising series used improvisational performances and featured a rotating group of comedians and actors, including Nicole Sullivan, Debra Wilson, Aries Spears, Jim Gaffigan, Michael Ian Black, Kathy Griffin, Tracy Morgan, and Guillermo Diaz. Spanish-language versions used performers connected with Otro Rollo. A 2007 limited-time Undercover Orange variant, including a diet version, supported the release of Get Smart. Sierra Mist also sponsored Major League Soccer, including the New England Revolution and D.C. United. That league relationship ended in 2015 after Coca-Cola became an MLS and United States Soccer Federation partner. PepsiCo discontinued Sierra Mist in January 2023. Starry replaced it as PepsiCo's lemon-lime soft-drink brand. Accordingly, Sierra Mist's lifecycle ended after more than two decades of national-market distribution, multiple sweetener and formula revisions, a temporary rebrand, and sustained competition in a mature soft-drink category.
