The 20 Best Low-Carb Craft Beers for Keto Diets

Slightly Mighty India Pale Ale

Dogfish Head Craft Brewery

Carbs: 3.6 grams

ABV: 4 percent

IBU: 30

Calories: 95

Poised to attract the calorie- and carb-counting beer drinkers, Dogfish Head is releasing Slightly Mighty IPA in 12-ounce cans in select states in April. This IPA carries tropical aromas, including pineapple, mango, coconut and citrus. Slightly Mighty IPA is building on Dogfish Head’s previous release of SeaQuench Ale, billed as the most “thirst-quenching” ale, which comes brimming with electrolytes. It also happened to become Dogfish Head’s fasting-growing beer in its history.

Slightly Mighty IPA uses one of the hallmark keto-friendly sweeteners – monk fruit. Sugars are simple carbohydrates and are therefore real keto-killers. For reference, one tablespoon of maple syrup contains over 50 calories and 13 grams of carbs. 100 percent pure maple syrup is acceptable on the paleo diet, but it could wreck someone in ketosis. One teaspoon of monk fruit sweetener has only 0.4 grams of carbohydrates, so it would take about 80 teaspoons of monk fruit sweetener just to consume 30 grams of carbs, which is a common daily allowance on the keto diet.

Later this year, SeaQuench and Slightly Mighty will join SuperEIGHT, 5.3 percent fruit-infused sour, and Namaste White, a 4.8 percent Belgian-style wheat beer, in a variety 12-pack Dogfish Head has dubbed its Activity Box.

Shiner Light Blonde

Spoetzl Brewery

Carbs: 3.8 grams

ABV: 4.2 percent

Calories: 99

The second and final beer by Spoetzl Brewery that's under 4 carbs per serving, Shiner Light Blonde is one of the brewery's most notable flagship brews and serves as a craft beer replacement for the juggernaut macro lagers. Full-bodied and flavorful with only 99 calories and 3.8 carbs, this beer is a godsend for keto dieters.

Brut IPA

Brewery Ommegang

Carbs: 3.9 grams

ABV: 6.3 percent

Calories: 140

Another Brut IPA on this list, Brewery Ommegang in Cooperstown, New York released this low-carb brew late last year, and it has flown under the radar for many keto dieters. With under 4 carbs per serving and the bone-dry, lip-smacking mouthfeel befitting of its Brut IPA style, craft beer fans on the keto diet should seek out this lightly hoppy, champagne-inspired IPA.

Kahana Blonde

Kona Brewing Co.

Carbs: 4 grams

ABV: 4.4 percent

Calories: 99

As a Blonde Ale, Kona Brewing Co.'s Kahana features a bit more complexity and flavor than, say, a macro lager might to discerning keto dieters. With a light but spritzy mouthfeel and featuring flavorful Galaxy and Citra hops, this is a delectable low-carb craft brew.

Enterprise Dry-Hopped Lager

Green's Beer 

Carbs: 4 grams

ABV: 4.1 percent

Calories: 66

One way in which brewers can lower the carbohydrate counts in their beers is through crafting gluten-free beers. Green's Beer has long been at the forefront of this burgeoning scene, and the brewery's Enterprise Dry-Hopped Lager has a minuscule 66 calories and only 4 grams of carbs per serving.
