How many carbs in an ultra-low-carb beer?
Keto-friendly
Yes. A 12 oz ultra-low-carb beer has about 2–3 g of carbs, which fits easily in a keto day.
Where the carbs come from
Brewed with extended fermentation so yeast eats nearly all the sugar.
Look for “2.6 g” on the label.
How to order it
Check the can: these are usually labeled around 2 to 3 grams of carbs.
Beer & Seltzer, lowest to highest
Beer keeps some of the malt sugar and starch that yeast did not ferment, which is why a regular beer has more carbs than a glass of dry wine. Light and ultra-low-carb beers are brewed to ferment almost all of it out.
