Frequently Asked Questions

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.
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.
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.
Mountain Dew contains slightly more sugar: 46g per 12oz can versus Pepsi's 41g per 12oz can. Mountain Dew also has more calories: approximately 170 per 12oz versus 150 for Pepsi. Both are available in zero sugar or diet variants (Pepsi Zero Sugar, Mountain Dew Zero Sugar) that eliminate the sugar content using artificial sweeteners. For calorie or sugar-conscious consumers, the zero sugar variants are nutritionally comparable across the two brands.
Mountain Dew's original flavor is a sweet, citrus-forward carbonated soda with a bright yellow-green color and a slightly tart citrus finish. Its flavor profile is often described as a blend of lemon, lime, and orange with a sweet citrus dominant note. It is significantly different from cola — Pepsi's caramel, vanilla, and cola flavors share nothing with Mountain Dew's citrus profile. Mountain Dew's sweetness level is high; its flavor is intense rather than subtle. The hundreds of limited-edition Mountain Dew variants (Baja Blast, Code Red, Voltage) each add distinct fruit or berry profiles to the base citrus character.
Expert Analysis: Pepsi vs Mountain Dew
Pepsi and Mountain Dew are both PepsiCo products — a fact that makes this comparison unusual among brand rivalries, since both brands share the same corporate parent, production infrastructure, and distribution network. What the comparison captures is the difference between two very distinct carbonated beverage philosophies within the same company's portfolio.
Pepsi (originally "Brad's Drink," renamed Pepsi-Cola in 1898) is a cola: a carbonated beverage flavored with caramel color, phosphoric acid, and a proprietary blend of flavors anchored by vanilla and citrus notes. PepsiCo's flagship product has competed directly with Coca-Cola for over 120 years, and the rivalry between Pepsi and Coke is one of the most studied brand competitions in marketing history. Pepsi's flavor profile is generally considered slightly sweeter than Coca-Cola Classic, with a somewhat more prominent vanilla note and less pronounced caramel bitterness — a distinction validated by the famous "Pepsi Challenge" blind taste tests of the 1970s-80s, where Pepsi frequently won initial sip preference even among self-described Coke drinkers. Despite this, Coca-Cola's market share has generally exceeded Pepsi's in U.S. soft drink retail for decades — a testament to the power of brand familiarity and consumer habit over blind taste preference.
Mountain Dew, created in 1940 by Tennessee bottlers Barney and Ally Hartman and acquired by PepsiCo in 1964, is categorically different: a citrus-flavored soda with a bright yellow-green color and a caffeine content significantly higher than Pepsi (54mg per 12oz vs Pepsi's 38mg). Mountain Dew's flavor is sweet, citrus-forward (primarily lemon-lime-orange), and highly carbonated. It has developed one of the most loyal cult followings in the American soft drink market — particularly among gaming communities, rural markets, and youth demographics — through decades of extreme sports sponsorship, gaming tie-ins (Gamer Fuel variants), and a relentless limited-edition flavor strategy that keeps consumer engagement high. Mountain Dew's brand extensions (Code Red, Voltage, Baja Blast, Live Wire) have been among the most successful flavor line extensions in any soft drink category.

Nutritionally, both are comparable in sugar content — a 12oz can of Pepsi contains 41g of sugar and 150 calories; Mountain Dew contains 46g of sugar and 170 calories. Mountain Dew's higher caffeine (54mg vs 38mg per 12oz) is a relevant difference for consumers tracking caffeine intake. Both are available in diet/zero sugar variants (Pepsi Zero Sugar, Mountain Dew Zero Sugar) that use aspartame and acesulfame potassium.
The comparison is really about preference category: Pepsi is a cola with the heritage and versatility to pair with food and function as a general-purpose soft drink; Mountain Dew is a citrus soda with a specific, intense flavor profile and an energizing caffeine level that drives distinct use occasions. They appeal to overlapping but distinct consumer groups.
