Which Contains More Sugar: Pepsi or Coke?

3 min read

A standard 12-ounce can of Pepsi contains 41 grams of sugar, slightly more than the 39 grams found in a 12-ounce can of Coca-Cola. This small difference contributes to subtle flavor variations, with Pepsi often tasting a bit sweeter, especially in a side-by-side comparison.

Quick Summary

A comparison of standard 12-ounce cans reveals that Pepsi contains slightly more sugar than Coke. Learn the exact nutritional details, including sugar, calories, and caffeine, for both popular colas. Discover how these minor differences in sweetness and flavor profile are perceived by consumers.

Key Points

  • Pepsi has more sugar: A standard 12-ounce can of Pepsi contains 41 grams of sugar, while a 12-ounce can of Coca-Cola has 39 grams.

  • The difference is minimal: The 2-gram sugar difference between a can of Pepsi and a can of Coke is considered nutritionally insignificant and doesn't affect overall health risks.

  • Sugar content varies with serving size: The sugar content increases proportionally with serving size, so a larger bottle contains much more sugar than a single can.

  • Flavor difference is due to more than sugar: Pepsi's use of both phosphoric and citric acid gives it a slightly sweeter, more citrus-forward flavor profile compared to Coke's use of only phosphoric acid.

  • Both are high in added sugar: Regardless of which has more, both sodas exceed the recommended daily sugar intake in a single serving, contributing only empty calories.

  • Artificial sweetener options are available: Diet and Zero Sugar varieties of both Pepsi and Coke offer sugar-free alternatives for those monitoring their intake.

Pepsi vs. Coke: A Head-to-Head Sugar and Nutrition Comparison

The long-standing rivalry between Pepsi and Coke extends beyond brand loyalty to subtle differences in their chemical composition and taste profile. While both are loaded with added sugar, a closer look at their nutrition facts reveals a definitive answer to the question of which contains more sugar.

Breaking Down the Sweetness: By the Can

For many consumers, the most relevant unit of measurement is the standard 12-fluid-ounce (355ml) can. Here is a direct comparison of the sugar content based on this common serving size:

  • Pepsi: Contains 41 grams of total sugars.
  • Coca-Cola: Contains 39 grams of total sugars.

This means a can of Pepsi has 2 grams more sugar than a can of Coke. When converted to teaspoons, this equates to roughly 10.25 teaspoons for Pepsi and 9.75 teaspoons for Coke, a significant amount of added sweetener in either case.

The Flavor Impact: Why a Little Difference Matters

While a 2-gram difference in sugar might seem insignificant, it plays a role in how the drinks taste. The flavor profiles of Pepsi and Coke, though similar, have distinct characteristics that are partly influenced by their sugar and acid levels. Pepsi uses both phosphoric and citric acid, which enhances the citrus flavors and contributes to its slightly sweeter taste profile. In contrast, Coke uses only phosphoric acid, leading to a smoother taste with more vanilla and spicy notes. The slight additional sweetness in Pepsi is sometimes perceived as a more immediate 'burst' of flavor during a taste test.

Serving Sizes and Hidden Sugars

It's important to remember that the sugar content changes with serving size. Larger bottles, such as the 20-ounce bottle, contain considerably more sugar, and often multiple servings, despite what marketing might suggest. For example, a 20-ounce bottle of Coke can have 65 grams of sugar, and a similar-sized Pepsi bottle may contain even more. This escalation of sugar intake is a critical consideration for health-conscious consumers.

The Health Implications of Both Colas

Regardless of which contains more sugar, both colas exceed the daily recommended intake of added sugars for most adults in a single serving. Excessive consumption of sugary drinks is linked to numerous health issues, including weight gain, an increased risk of type 2 diabetes, and dental decay. While the taste preference is a matter of personal opinion, the nutritional reality is that both drinks offer little more than empty calories.

Total Sugars 41g 39g
Caffeine 38mg 34mg

Beyond the Original: Diet and Zero Sugar Options

For those seeking alternatives with less or no sugar, both Pepsi and Coke offer a range of products. Diet Pepsi and Diet Coke use artificial sweeteners to provide a sweet taste without the calories or sugar. Pepsi Zero Sugar and Coke Zero Sugar also use artificial sweeteners and have slightly different flavor blends compared to their diet counterparts. The emergence of these options reflects growing consumer awareness and the industry's response to public health concerns.

Conclusion

Ultimately, Pepsi contains a very slightly higher amount of sugar per standard 12-ounce can than Coca-Cola. While this difference is small, it contributes to the nuanced flavor that has fueled the famous cola wars for decades. For health reasons, however, the minimal gap in sugar content is largely insignificant, as both beverages contain an excessive amount of added sugar relative to dietary guidelines. Making a choice between the two based on flavor preference is a matter of personal taste, but from a nutritional standpoint, moderation is the best policy for either option. When comparing, the nutritional labels are the most reliable source for making an informed decision about sugar intake.
