The Surprising Truth: Zero Grams of Residual Sugar
Contrary to popular assumption, a standard 12-ounce can of Pabst Blue Ribbon (PBR) beer contains 0 grams of residual sugar. The key word here is 'residual,' which refers to the unfermented sugars remaining after the brewing process is complete. While sugar is essential for making beer, the yeast consumes nearly all of it, converting it into alcohol and carbon dioxide. This process leaves behind very little to no sugar in the final product.
The Science of Fermentation
To understand why PBR has no sugar, it's crucial to look at how beer is made. The main ingredients in PBR are water, barley, rice, hops, and corn syrup. Here’s the step-by-step process that eliminates the sugar:
- Mashing: The brewers heat malted barley and other grains in water. This process activates enzymes that break down the starches into simpler fermentable sugars, including glucose and maltose, creating a sweet liquid called wort.
- Boiling: Hops are added to the wort during boiling, which adds bitterness to balance the sweetness from the malt. This mixture is sterilized and prepared for the next step.
- Fermentation: The liquid is cooled and yeast is added. The yeast consumes the fermentable sugars in the wort and metabolizes them into alcohol and carbon dioxide.
- Aging/Cellaring: The beer is aged to develop its final flavor profile. By the time this process is complete, most of the fermentable sugars have been fully converted, resulting in a product with virtually zero sugar content.
The Corn Syrup Misconception
A common point of confusion is PBR's use of corn syrup in its brewing process. Some people mistakenly believe this means the final beer is loaded with the same type of sugar found in soda. However, this isn't the case.
Pabst uses corn syrup not as a sweetener, but as a fermentable sugar source. The yeast consumes the sugars in the corn syrup, just as it does with the sugars from the malted barley, converting them into alcohol and CO2. This process is crucial for achieving the beer's specific alcohol content and body. The final product does not contain high-fructose corn syrup, and the initial corn syrup has been fermented out. The use of corn syrup helps create the clean, crisp finish characteristic of many American lagers.
The Difference Between Carbs and Sugar in Beer
It's important to distinguish between total carbohydrates and sugar content. While a can of PBR has 0 grams of sugar, it still contains about 12-13 grams of total carbohydrates.
These carbohydrates come from two main sources: alcohol and unfermentable sugars, also known as dextrins. Dextrins are more complex starches that the yeast cannot fully metabolize, and they remain in the beer, contributing to its body and flavor. While these carbohydrates provide calories, they do not have the same metabolic effect as simple sugars.
PBR Nutritional Facts (per 12 fl oz can)
- Calories: 140-153
- Carbohydrates: 12-13 grams
- Sugars: 0 grams
- Fat: 0 grams
- Protein: ~1-1.6 grams
- Alcohol by Volume (ABV): 4.7%
A Comparison of Sugar Content in Common Beers
To put PBR's sugar content in perspective, here is a table comparing it to other beer types and a common sugary drink.
| Beverage (12 oz) | Sugar (grams) | Carbohydrates (grams) |
|---|---|---|
| Pabst Blue Ribbon (PBR) | 0g | 12-13g |
| Light Beer (e.g., Bud Light) | 0g | ~4.6g |
| Non-Alcoholic Beer (example) | ~28g | ~28g |
| Craft IPA (example) | <1g | ~10g+ (varies) |
| Coca-Cola | ~39g | ~39g |
Note: Non-alcoholic beer contains high sugar levels because the fermentation is stopped before the sugars can be fully converted to alcohol. The exact nutritional content varies by brand.
Making Informed Choices
For those watching their sugar intake, PBR is a much better choice than sugary cocktails or soda. The main source of calories in beer comes from alcohol and carbohydrates, not sugar. However, moderation is always key, as excessive alcohol consumption carries its own health risks and contributes to overall calorie intake.

Conclusion
In summary, a can of Pabst Blue Ribbon has no sugar. The brewing process, which involves yeast fermenting sugars from barley and corn syrup into alcohol, leaves behind 0 grams of residual sugar in the finished product. While PBR does contain carbohydrates, these are primarily unfermentable starches and should not be mistaken for simple sugars. This makes PBR and many other standard lagers a low-sugar option compared to many other popular beverages, though all alcoholic drinks should be consumed responsibly.
