{"slug":"pepsi-vs-mountain-dew","question":"Pepsi vs Mountain Dew","answer":"Pepsi is the second-largest soft drink in America with 7.97% market share and a classic cola flavor, while Mountain Dew is a citrus-based energy drink with 6.1% market share positioned for extreme sports enthusiasts. Pepsi dominates in overall market presence, while Mountain Dew appeals to consumers seeking higher caffeine and bold citrus taste.","answer_curated":true,"verdict":"Choose Pepsi if you prefer a balanced cola taste, larger product variety (including snacks), and lower sugar content—it dominates the broader market with wider appeal. Choose Mountain Dew if you want higher caffeine content, bold citrus flavor, and appeal to active/extreme sports culture with unique limited-edition offerings like the 2026 American Dew rebrand.","keyDifferences":[{"label":"Market Share in US (2026)","winner":"a","entityAValue":"7.97%","entityBValue":"6.1%"},{"label":"Caffeine Content per 12oz","winner":"b","entityAValue":"38mg","entityBValue":"54mg"},{"label":"Primary Flavor Profile","winner":"tie","entityAValue":"Cola (traditional)","entityBValue":"Citrus (lemon-lime blend)"},{"label":"Target Demographic","winner":"tie","entityAValue":"General consumers, families","entityBValue":"Youth, extreme sports enthusiasts"},{"label":"Sugar Content per 12oz","winner":"a","entityAValue":"41g","entityBValue":"46g"}],"winner":{"slug":"pepsi","name":"Pepsi"},"confidence":"high","entities":[{"name":"Pepsi","slug":"pepsi","url":"https://www.aversusb.net/entity/pepsi","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/pepsi"},{"name":"Mountain Dew","slug":"mountain-dew","url":"https://www.aversusb.net/entity/mountain-dew","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/mountain-dew"}],"faqs":[{"question":"Is Pepsi or Mountain Dew more popular?","answer":"Pepsi is significantly more popular globally by sales volume — it is PepsiCo's flagship brand and one of the two most recognized soft drink brands in the world. In the United States, Pepsi consistently ranks as the second or third best-selling carbonated soft drink (behind Coca-Cola and sometimes Diet Coke). Mountain Dew is also a major brand — typically ranking in the top 5 U.S. soft drinks — and has an exceptionally loyal consumer base, particularly strong in the U.S. market. In terms of U.S. retail market share, Pepsi substantially outsells Mountain Dew, though both are among the most commercially successful drinks in any segment."},{"question":"Does Mountain Dew have more caffeine than Pepsi?","answer":"Yes. Mountain Dew contains approximately 54mg of caffeine per 12oz serving, while Pepsi contains approximately 38mg per 12oz. This makes Mountain Dew roughly 42% higher in caffeine than Pepsi — though both are substantially lower than coffee (95-200mg per 8oz) or energy drinks (80-150mg per 8oz). Mountain Dew's higher caffeine is intentional in its brand positioning as an energizing, stimulating beverage. Mountain Dew Game Fuel and other energy-focused variants can contain higher caffeine levels still."},{"question":"Are Pepsi and Mountain Dew owned by the same company?","answer":"Yes. Both Pepsi and Mountain Dew are owned and produced by PepsiCo, Inc. Mountain Dew was independently created in 1940 and acquired by PepsiCo in 1964. PepsiCo's broader portfolio includes Gatorade, Lay's, Doritos, Lipton (in partnership), Tropicana, Quaker Oats, and hundreds of other brands. Pepsi and Mountain Dew compete in different flavor categories (cola vs citrus soda) rather than directly against each other."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/pepsi-vs-mountain-dew","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/pepsi-vs-mountain-dew), Pepsi is the second-largest soft drink in America with 7.97% market share and a classic cola flavor, while Mountain Dew is a citrus-based energy drink with 6.1% market share positioned for extreme spo","dateModified":"2026-08-18T09:00:23.987Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/pepsi-vs-mountain-dew","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/pepsi-vs-mountain-dew","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/pepsi-vs-mountain-dew","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/pepsi-vs-mountain-dew#claimreview","url":"https://www.aversusb.net/compare/pepsi-vs-mountain-dew","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Pepsi is better than Mountain Dew for most use cases","reviewBody":"Pepsi is the second-largest soft drink in America with 7.97% market share and a classic cola flavor, while Mountain Dew is a citrus-based energy drink with 6.1% market share positioned for extreme sports enthusiasts.
