The query 'Does mist have caffeine?' is a common one, fueled by the evolution of PepsiCo's lemon-lime soda lineup. The answer, however, is not a simple yes or no, as it depends entirely on which product is being referenced. The most widely recognized 'Mist' sodas, including the now-discontinued Sierra Mist, its short-lived successor Mist Twst, and the current replacement Starry, are all definitively caffeine-free. The confusion arises because other, less-common brands and products with 'mist' in their name do contain caffeine, and the name changes have created ambiguity.
The Legacy of Sierra Mist: A Caffeine-Free Classic
Since its introduction in 1999, PepsiCo's flagship lemon-lime soda, Sierra Mist, was positioned as a crisp, caffeine-free alternative to other soft drinks. For over two decades, its formula was adjusted, but its commitment to being a caffeine-free beverage remained constant, serving as a direct competitor to Coca-Cola's Sprite, which is also caffeine-free. The brand built a reputation for being a light, family-friendly option that wouldn't contribute to caffeine intake.
The Evolution to Mist Twst and Back
In a branding pivot, PepsiCo replaced Sierra Mist with Mist Twst in early 2016, a change that also maintained the soda's caffeine-free status. Despite the new name and a formula tweak (the reintroduction of high-fructose corn syrup), the product remained consistent on this key health consideration. The company eventually reversed course, bringing back the Sierra Mist name in 2018, again as a caffeine-free offering, before its final discontinuation.
Starry: PepsiCo's Modern Caffeine-Free Lemon-Lime
In January 2023, PepsiCo made the strategic decision to discontinue Sierra Mist due to declining market share and replaced it with a new lemon-lime soda called Starry. Just like its predecessors, Starry is also a caffeine-free beverage, ensuring that PepsiCo continues to have a zero-caffeine option in this competitive soft drink category.
When "Mist" Does Have Caffeine: Other Brands and Products
While the main PepsiCo lemon-lime products have been consistently caffeine-free, a quick look beyond this specific lineage reveals several products that incorporate 'mist' and do contain caffeine. It is crucial to read labels, especially when exploring less-common or international options.
Faygo Moon Mist: A Low-Caffeine Example
For example, Faygo, a brand known for its wide variety of flavors, offers a citrus soda called Moon Mist. Unlike PepsiCo's offering, Faygo Moon Mist does contain a modest amount of caffeine. A 12-ounce can contains 19.7 mg of caffeine, a relatively low amount compared to other caffeinated sodas and energy drinks.
Mist Structure: A Caffeinated Protein Drink
For a completely different product type, the brand 'mist structure' offers a sugar-free, carbonated protein drink that is activated with caffeine from yerba mate leaves and green coffee beans. This product is an excellent example of how the word 'mist' can be used in a way that is completely unrelated to the traditional lemon-lime soda and does contain a significant amount of caffeine (40 mg per 330 ml can).
Best Choice Country Mist: A Discontinued Exception
Older and discontinued products can also be a source of confusion. The Best Choice Country Mist Citrus Soda, for example, contained caffeine, as noted by the Environmental Working Group (EWG). This historical example underscores the importance of checking the ingredient list on any product, especially if it's an older stock or from a lesser-known brand.

How to Identify a Caffeinated Beverage
When in doubt, always read the label. By law, food and beverage companies must disclose their ingredients and nutritional information. For products sold in the United States, if caffeine is added, it must be listed in the ingredient panel. Even if it's not listed, if a product like 'mist structure' includes caffeinated ingredients such as yerba mate or green coffee bean extract, it will have a caffeine content noted. For more information, see Healthline's guide on reading nutrition labels and caffeine content. Consulting the official company websites or FAQs, as with PepsiCo's FAQ page for Mug Root Beer which states it is caffeine-free, is also a reliable method.
Conclusion: Does Mist Have Caffeine? The Final Verdict
In summary, the most common answer to the question "Does mist have caffeine?" is no, assuming the person is referring to PepsiCo's popular lemon-lime sodas like the former Sierra Mist and its current replacement, Starry. These beverages have been consistently caffeine-free. However, the use of "mist" in other product names, from niche soda brands like Faygo to specialized protein drinks, means that a small amount of caffeine is not unheard of. Always check the nutrition facts and ingredient list to be certain of a product's caffeine content, especially with the frequent rebrands in the soft drink industry.
