The Science Behind Low-Carb and Low-Calorie Beer
To understand what beer has the fewest carbs and calories, it's helpful to know where these components come from. The primary sources of calories in beer are alcohol and residual sugars (carbohydrates) left after fermentation.
Alcohol Content: Alcohol contains roughly 7 calories per gram, nearly as dense as fat (9 calories per gram). This is why beers with lower alcohol by volume (ABV) often have fewer calories overall. Higher ABV beers, such as imperial stouts or double IPAs, naturally have a much higher calorie count.
Carbohydrates: These are primarily residual sugars from the grains used in brewing. Brewers can use specific enzymes or fermentation techniques to break down more of these sugars, resulting in a drier, less caloric beer. This is the secret behind many of the 'ultra-light' and 'keto-friendly' options on the market today.
Top Alcohol-Based Options for Minimum Carbs and Calories
For those who prefer a traditional alcoholic beer but with a minimal nutritional impact, several brands stand out. These brewers have perfected the art of creating a crisp, flavorful beer with an impressively low calorie and carb count per 12-ounce serving.
- Budweiser Select 55: This is often cited as one of the lowest-calorie beers available, clocking in at just 55 calories and 1.9g of carbs. It's a very light, easy-drinking option for those prioritizing minimum intake.
- Miller64: Another contender in the ultra-light category, Miller64 offers 64 calories and 2.4g of carbs per serving. It provides a slightly higher ABV than Select 55 while keeping calories very low.
- Bud Light Next: Anheuser-Busch's zero-carb offering, Bud Light Next, has 80 calories and 0g of carbs. This is a game-changer for those on strict ketogenic or carb-free diets who want an alcoholic beverage.
- Michelob Ultra Pure Gold: An organic light lager, Michelob Ultra Pure Gold has 85 calories and 2.5g of carbs, with a 3.8% ABV. It's a popular choice for those seeking a balance of flavor and low calories.
- Corona Premier: With 90 calories and 2.6g of carbs, Corona Premier offers a crisp, refreshing taste with a subtle hint of citrus. It's a great choice for those who enjoy a traditional light Mexican lager.

Flavor vs. Function: Choosing Your Low-Calorie Brew
While the macro breweries dominate the absolute lowest-calorie categories, many craft brewers have also stepped up to meet the demand for lighter options. These often prioritize flavor more heavily, using alternative hops or brewing methods to compensate for the lower malt presence.
- Craft Low-Calorie IPAs: Brewers like Dogfish Head and Lagunitas offer lighter IPAs that still provide a hoppy, full flavor experience. Dogfish Head Slightly Mighty has 95 calories and 3.6g carbs, while Lagunitas DayTime IPA comes in at 98 calories and 3g carbs.
- Variety in Style: Some breweries offer low-carb options in various styles. For example, Deschutes makes 'Da Shootz!', a pilsner with 99 calories and 4.2g of carbs, appealing to drinkers who prefer a different flavor profile than a light lager.
The Ultra-Low Realm: Non-Alcoholic Beers
For those seeking the absolute minimum in both carbs and calories, non-alcoholic (NA) beers are the leading choice. With the alcohol removed, much of the caloric content is also eliminated. The flavor profiles of NA beers have significantly improved in recent years, making them a viable alternative.
- Partake Brewing IPA: A frontrunner in the NA market, Partake's IPA offers a remarkable 10 calories and 0g of carbs per 12-ounce can. This makes it an excellent option for those following a strict low-carb diet.
- Suntory All-Free: This alcohol-free option is known for its simplicity and low nutritional impact, containing 0 calories and just 1g of carbs.
- Athletic Brewing Co. Athletic Lite: A popular option for a post-workout recovery drink, this NA beer has 25 calories and 5g of carbs.
The Future of Light Beer
Brewing innovation continues to push the boundaries of what is possible in the low-calorie and low-carb space. Advances in yeast strains, enzyme usage, and fermentation control mean that drinkers no longer have to compromise on flavor to meet their dietary goals. The market is also seeing more variety beyond traditional light lagers, with low-calorie IPAs, sours, and other styles becoming more common. This proliferation of choice allows health-conscious consumers to enjoy a wide range of beer types while managing their intake effectively.
Conclusion
The quest to find what beer has the fewest carbs and calories leads to a clear winner in Budweiser Select 55 and Bud Light Next for alcoholic options, with NA beers from brands like Partake and Suntory taking the prize for overall lowest counts. The best choice ultimately depends on your specific goals, whether it's minimizing calorie intake, eliminating carbs entirely, or finding a flavorful brew that fits your dietary plan. By considering ABV, consulting nutrition labels, and exploring both macro and craft options, you can enjoy beer responsibly and mindfully.
