Regular beer contains almost no sugar. According to the FoodData Central database of the United States Department of Agriculture (USDA), a regular beer contains 0 grams of sugars per 100 grams and 3.55 grams of carbohydrates. The explanation lies in fermentation, during which the yeast turns the sugars from the malt into alcohol and carbon dioxide. What remains in the glass is mostly dextrins, carbohydrates the yeast cannot ferment.<\/p>\n

The question makes sense because beer starts life as a very sweet wort. Malted barley provides starch, mashing turns it into sugars, and only fermentation decides how many of them reach the bottle. That is why two beers brewed with the same malt can end up with very different sugar profiles, and why many non-alcoholic beers retain more sugar than regular beer.<\/p>\n

Why Beer Has Almost No Sugar Even Though It Is Made From Malt<\/h2>\n

During mashing, malt enzymes break the grain’s starch down into simpler sugars. The main one is maltose, along with glucose and maltotriose. That sweet wort is boiled with hops, cooled and pitched with yeast, which over several days consumes those sugars and converts them into ethanol and carbon dioxide. In a well fermented beer the yeast uses up practically all the simple sugars available.<\/p>\n

What the yeast cannot digest are dextrins, longer sugar chains that add body and a little sweetness but that nutrition tables do not count as sugars. That is why a label can show several grams of carbohydrates and almost no sugars. Readers who want to turn those carbohydrates into energy will find the full method in our guide on how to calculate the calories in a beer<\/a>, where alcohol weighs more than carbohydrates in the total.<\/p>\n

Sugar Versus Carbohydrates on a Beer Label<\/h2>\n

USDA data show the difference clearly. Regular beer lists 43 kilocalories, 3.55 grams of carbohydrates, 0 grams of sugars and 3.9 grams of alcohol per 100 grams, according to FoodData Central entry 168746<\/a>. For a 355 milliliter can, that works out to about 153 kilocalories and about 12.6 grams of carbohydrates, with no declared sugars.<\/p>\n

Light beer lowers the figure even further. USDA entry 168749<\/a> gives it 29 kilocalories, 1.64 grams of carbohydrates and 0.09 grams of sugars per 100 grams, leaving a can at around 5.8 grams of carbohydrates. Light beer also contains less alcohol, 3.1 grams per 100 grams according to the same entry, which accounts for a good part of its lower calorie count.<\/p>\n

Why Non-Alcoholic Beer Can Have More Sugar Than Regular Beer<\/h2>\n

Non-alcoholic beer reverses that logic. Some are made by stopping fermentation early or with yeasts that barely ferment maltose, and in both cases the wort sugars are never turned into alcohol. Others are dealcoholized after a full fermentation, and some producers add wort or sugars at the end to restore lost body and sweetness. The most common techniques are explained in our overview of yeasts for brewing non-alcoholic beers<\/a>.<\/p>\n

In its entry 174863<\/a> the USDA groups malt beverages, including non-alcoholic beer, and assigns them 8.05 grams of carbohydrates per 100 grams, all of them sugars. That category also includes sweetened malt drinks, so the figure works as a general reference and not as the value for any specific brand. The Profeco analysis summarized below confirms that sugar content varies widely between brands.<\/p>\n

What Profeco Found in Mexican Beers<\/h2>\n

Mexico’s Federal Consumer Protection Agency (Profeco) published an analysis in September 2024, in its Revista del Consumidor, of 19 products sold in the country, 12 low alcohol beers and 7 non-alcoholic drinks, as reported by Infobae<\/a>. The low alcohol beers registered between 0.02 and 0.09 grams of sugars per 100 milliliters, and the non-alcoholic drinks between 0.08 and 3.56 grams, according to El Financiero<\/a>. Among the most sugary were Mahou 0,0, with 3.19 grams per 100 milliliters, and Tecate 0,0, with 2.84 grams.<\/p>

Profeco also noted that in Mexico a drink can only be called beer if it contains between 2% and 20% alcohol, and that below that range it must be labeled a non-alcoholic drink, according to El Financiero. The results follow the same trend as the USDA entry. In this study, the non-alcoholic drinks contained far more sugar than the low alcohol beers.<\/p>\n

Which Beer Styles Keep More Residual Sugar<\/h2>\n

Differences also exist within alcoholic beer. Highly fermented, dry beers, such as most industrial lagers or saisons, leave very little sugar. At the opposite end are styles that seek sweetness, such as milk stouts, which include lactose, a sugar that brewer’s yeast does not ferment and which therefore reaches the glass intact.<\/p>\n

High gravity beers such as barley wine or some quadrupels can keep more residual sugar when the yeast gives out before consuming all the wort. Fruit beers, flavored beers and some radlers, which mix beer with lemonade or juice after fermentation, also add sugars that never pass through the yeast.<\/p>\n

Frequently Asked Questions (FAQ)<\/h2>\n

1. Does beer have added sugar?<\/h3>\n

Conventional beer does not usually have sugar added after fermentation. Some recipes use sugars or syrups as adjuncts during brewing, and the yeast ferments them just like maltose. Sugars remain in the final product when the yeast does not ferment them, such as the lactose in milk stouts or the wort in many non-alcoholic beers, or when they are added after fermentation, as in fruit beers, flavored beers and radlers.<\/p>\n

2. How much sugar is in a can of beer?<\/h3>\n

According to the USDA, regular beer has 0 grams of sugars per 100 grams, so a 355 milliliter can does not provide any declared sugars either. It does contain about 12.6 grams of carbohydrates. The exact figure varies by brand.<\/p>\n

3. Does beer raise blood sugar?<\/h3>\n

The carbohydrates in beer can raise blood glucose at first, and alcohol can lower it later by slowing glucose production in the liver. The effect depends on the amount, the style and the individual. Our article on whether a person with diabetes can drink beer<\/a> covers this point with the recommendations of the American Diabetes Association.<\/p>\n

4. Does non-alcoholic beer have sugar?<\/h3>\n

Many non-alcoholic beers have more sugar than regular beer, because fermentation stops before the sugars turn into alcohol or because wort is added at the end. In the 2024 Profeco analysis, the non-alcoholic drinks reached up to 3.56 grams of sugars per 100 milliliters, compared with a maximum of 0.09 grams in the low alcohol beers.<\/p>\n

5. Does light beer have less sugar?<\/h3>\n

Yes. According to the USDA, light beer has 0.09 grams of sugars and 1.64 grams of carbohydrates per 100 grams, compared with 3.55 grams of carbohydrates in regular beer. It also provides fewer calories, 29 kilocalories per 100 grams versus 43, partly because it contains less alcohol.<\/p>\n
