Michelob Ultra and Light Beer: Calories and Carbs

By the DrinkLeader team · Published 2026-10-13 · Data updated 2026-10-13 · 8 min read

Michelob Ultra in the catalog is a 12 oz beer with 95 calories, 2.6g of carbs and 4.2% ABV. That puts it among the lightest mainstream lagers, but several rivals list similar or lower figures. This guide compares Michelob Ultra with the other big light beers and with regular lagers, using live catalog numbers.

What makes a beer "light"

Light beer is mostly a marketing and brewing category, not a legal nutrition standard. Light beers typically leave less residual carbohydrate in the finished beer and are often brewed to a slightly lower ABV. Since alcohol itself carries about 7 calories per gram and carbohydrate about 4, both changes reduce calories. TTB, which regulates beer labels, makes Serving Facts optional on beer, which means light beers that publish numbers do so voluntarily. The catalog uses the producer's stated numbers when available, and the methodology page explains how gaps are handled.

The big light beers compared

Here are the best-known light lagers in the catalog, all in 12 oz servings:

All of these list roughly 85 to 110 calories, but carbs spread from about 2.5g to 6.6g across the group. That spread is larger than the calorie spread, which is why carbs separate "light" beers more than calories do. The lowest-carb beers guide extends the list to craft and imported labels.

Michelob Ultra versus regular lagers

The contrast with full-calorie lagers is the main reason people pick Michelob Ultra:

The regular lagers in this table list about 145 calories and 10g of carbs, which is 4 times the carbs of a Michelob Ultra. Alcohol is similar, so the difference is mostly carbohydrate. The USDA FoodData Central database is a useful cross-check if you want an independent lab-style figure for a generic lager.

The Michelob Ultra family

The brand now spans several products, and not all are as light as the original:

Pure Gold lists slightly fewer calories than the original, while the Amber Max row lists more carbs than either. The brand also has seltzers:

These list 80 calories and about a gram of carbs at 4% ABV. And there is a non-alcoholic version:

Non-alcoholic beers in the catalog generally list more carbs than light lagers, even when calories are low; the non-alcoholic beer guide has the full comparison. Other Michelob products, such as Michelob Ultra flavored versions with tea or cider character, are not like the original and are worth checking individually on the brand page.

The lowest-carb beers near Michelob Ultra

Michelob Ultra is not alone at the low end. These beers list 3.3g of carbs or fewer and 100 calories or fewer:

The table includes imported and regional labels as well as American lights, and the serving sizes are not always 12 oz, so read the Serving column before comparing. Some entries are lower in ABV than Michelob Ultra, which pulls their calories down further. The catalog does not claim any one of these is the single lowest; the list simply shows who is in the same range.

Light beer versus a seltzer

A Michelob Ultra seltzer and a Michelob Ultra beer carry the same brand name but behave differently. The seltzers above list about 0g of carbs and 80 calories, against 2.6g and 95 for the beer. The seltzer lists fewer calories and fewer carbs at a similar ABV, though it tastes nothing like the beer, so the choice is partly about taste. Neither is a guarantee about how many drinks you have had: the NIAAA standard drink counts grams of alcohol, not brand names.

Pints, bottles and tall cans

Most light beer is sold in 12 oz cans and bottles, but bars pour pints, and cans now come in 16 oz and 24 oz formats. The numbers in the tables belong to the serving shown, so a 16 oz can of a beer listing 95 calories per 12 oz holds roughly a third more. If you order on draft, ask for the beer name, and then use the calories in alcohol guide to scale by pour size. The carbs in alcohol guide does the same for carbs.

How to use these numbers

For an everyday low-carb choice, a light lager with about 3g of carbs or fewer is a reasonable target, and the beer keto page shows which beers fit common carb limits. For calories, the under 100 calories list collects options across drink types. If you want to compare two specific beers, use the compare tool.

When comparing, look at three columns together rather than one. Calories tell you the energy in the can, carbs tell you how much of that is not alcohol, and ABV tells you how strong the drink is. A beer can look good on calories simply because it is weak, which is fine if you want less alcohol, but misleading if you assume a weaker beer is also lower in sugar. The reverse also happens, as the flavored Michelob Ultra products in the catalog show: a low ABV can come with far more carbs.

Remember that these figures are per 12 oz can. A pint is about 16 oz, so scale up by a third, and the FDA reminds readers that all nutrient amounts apply to one serving. NIAAA counts a 12 oz beer at about 5% as one standard drink; a light beer at 4% ABV is slightly less, but ABV on labels is rounded.
