Why Non-Alcoholic Beer Contains Carbohydrates
To understand why non-alcoholic (NA) beer contains carbohydrates, it's essential to look at the brewing process. Beer is traditionally made with four main ingredients: water, malted grain (usually barley), hops, and yeast. The carbohydrates come primarily from the malted grain.
During standard brewing, yeast ferments the sugars from the malted grain to produce both alcohol and carbonation. In contrast, NA beer is produced in several ways, and the chosen method significantly affects the final carbohydrate content.
- Dealcoholization: This method involves brewing a full-strength beer and then removing the alcohol. Techniques include vacuum distillation, which evaporates alcohol at a lower temperature, or reverse osmosis, which filters out the alcohol molecules. This process can sometimes leave behind a higher concentration of residual sugars, leading to a higher carb count than the alcoholic version.
- Limited Fermentation: Brewers can use special yeast strains or control the fermentation temperature to limit how much sugar is converted to alcohol. This stops the process when the alcohol content is low, but more unfermented sugars and thus, carbohydrates, remain in the final product.
- Brewing with 'Lazy Yeast': Some brewers use yeast strains that cannot ferment certain types of sugars, resulting in a low-alcohol, and potentially higher-sugar, beverage.
Regardless of the method, the starting point of malted grains ensures that some level of carbohydrates will almost always be present. The key takeaway is that an alcohol-free label doesn't automatically mean a low-carb drink.
Carbohydrate Content: NA Beer vs. Regular Beer
While it's a common assumption that NA beer will have fewer carbs than regular beer, this is not always the case. Some NA brands have developed innovative methods to produce truly low or zero-carb options, but others end up with higher carb levels, especially if sweetness is added back for flavor.
To see how carb counts stack up, here is a comparison of some popular NA beer brands and styles. Figures are approximate and can vary slightly based on recipe and region. Data is based on a standard 12-ounce serving.
| Brand & Style | Carbs (approx. per 12oz / 355ml) | Notes |
|---|---|---|
| Partake Brewing IPA | 0g | Specifically formulated to be zero-carb. |
| Suntory All-Free | 1g | Very low-carb option from a Japanese brand. |
| BrewDog Hazy AF | 2.3g | Another low-carb craft option. |
| Coors Edge | 8g | A mainstream NA with a moderate carb count. |
| Busch NA | 13g | A higher-carb mainstream option. |
| Heineken 0.0 | 16g | Higher in carbs and sugar than standard Heineken. |
| Clausthaler Original | 18.5g | An example of a traditional NA with a high carb count. |
The Low-Carb and Keto Diet Consideration
For individuals following a low-carb diet like keto, the carbohydrate content of NA beer is a critical factor. The ketogenic diet restricts daily carb intake to a very low level, often between 20 and 50 grams. A single serving of some NA beers could consume a large portion of this daily allowance.
Choosing a zero-carb brand like Partake or a very low-carb option from BrewDog or Big Drop is essential for staying in ketosis. Many traditional NA brands are simply not suitable for a strict keto lifestyle due to their high sugar and carb levels. Always check the nutritional label before buying.
Diabetes and Non-Alcoholic Beer
People with diabetes must be particularly mindful of their carbohydrate and sugar intake to manage blood glucose levels. Because NA beers often contain significant levels of sugars and high-glycemic carbohydrates, they can cause blood sugar spikes. Low-sugar or zero-sugar options are the safest choice, and consumption should always be in moderation and with food to slow sugar absorption. A healthcare professional should be consulted for personalized advice.
The Importance of Reading Labels
Given the wide variation in carb and sugar content, relying on the 'non-alcoholic' label alone is misleading. The only way to make an informed choice is to carefully read the nutritional label on the can or bottle. Manufacturers of low-carb, keto-friendly NA beers typically highlight this information clearly on their packaging or website. For example, the website for low-carb specialists like Dry Drinker provides a dedicated page for finding keto-friendly options, ensuring consumers can easily identify suitable products.
Conclusion
In summary, non-alcoholic beer does contain carbohydrates, and sometimes in surprisingly high amounts, especially when dealcoholization leaves behind residual sugars or additional flavorings are added. However, with the rise of health-conscious brewing, there is a growing selection of low-carb and even zero-carb NA beers available. For anyone on a low-carb diet, managing diabetes, or simply watching their carb intake, reading nutritional labels is non-negotiable. By choosing wisely, it's possible to enjoy the taste of a cold beer without derailing dietary goals.
How to Select a Low-Carb NA Beer
- Read the nutrition label first: This is the most accurate way to confirm carbohydrate and sugar content.
- Look for 'keto-friendly' labels: Some brands explicitly advertise their products as suitable for low-carb diets.
- Check the ingredients list: Be wary of added sugars or flavorings that might increase carb count.
- Consider low-calorie options: Lower calorie NA beers are often, but not always, lower in carbohydrates as well.
- Research brands online: Websites for specialized NA breweries often have detailed nutritional information and filtering options.

A Final Word on Carbohydrate Sources
Non-alcoholic beer's carb content comes from the malted grain used in brewing. While standard beer ferments these sugars into alcohol, NA brewing methods can leave significant amounts of sugar in the final product. Dealcoholization and arrested fermentation are two common techniques that can result in higher-carb beverages. However, dedicated low-carb brewers have created excellent zero or near-zero carb alternatives. For anyone monitoring carb intake, particularly for a keto diet or diabetes management, reading labels is the only reliable way to know what you are drinking.
What to Know About Non-Alcoholic Beer Carbs
- Carbs are a given: Non-alcoholic beer is not carb-free by default; it gets its carbs from the malted grains used in the brewing process.
- Varies by brand: The carb count can differ dramatically between brands and brewing methods, so checking nutritional labels is crucial.
- Not always lower than alcoholic beer: Some NA beers are surprisingly high in carbohydrates, sometimes even more so than their alcoholic counterparts due to retained sugars.
- Keto options exist: If following a ketogenic diet, seek out brands specifically formulated to be low or zero-carb, such as Partake.
- Pay attention to sugar: Sugars can be added for flavor after dealcoholization, which can significantly increase both carb content and glycemic impact.
Understanding NA Brewing and Carbs
- Brewing Process: NA beer is made using standard ingredients like malt, but brewing methods like dealcoholization or limited fermentation can affect the final carb count.
- Residual Sugars: Removing alcohol often leaves behind unfermented sugars, raising the carbohydrate level.
- Added Ingredients: Some producers add sweeteners like lactose or other natural flavors, which contributes to the total carb count.
- Method Matters: Techniques like vacuum distillation can impact flavor and sugar levels differently than methods like arrested fermentation.
- Zero-Carb Availability: Modern brewing has made it possible to find zero-carb and very low-carb NA beers for those with strict dietary needs.
