Although Guinness is a popular choice among beer drinkers, it isn’t suitable for those with celiac disease or gluten sensitivity. This is due to its malted barley content, a known source of gluten.

Remember, it’s essential to protect your health by avoiding products made from barley, wheat, rye, and other gluten-containing grains. 

Don’t worry, though! Plenty of gluten-free beer alternatives are made from grains like sorghum, rice, millet, or corn.

Is Guinness Stout?

Absolutely, you’re right on the money— stout is the distinctive style of beer that characterizes that rich, creamy brew you love so much. Guinness, indeed, falls under this category.

This dark, hearty beer is a derivative of the Porter style and offers an unforgettable, dense flavor. It’s characterized by robust, full-bodied flavors akin to chocolate, coffee, and caramel. 

Guinness, a perfect example of a stout, is known for its creaminess and profound depth of flavor. But remember, this one’s not safe for you if you’re gluten sensitive. 

Beer VS. Stout

You might wonder about the differences between generic and stout beer.

  • Well, beer is a broad term that covers various types of alcoholic drinks, including lagers, ales, IPAs, pilsners, and stouts. 
  • Meanwhile, stout is a subtype of beer recognized for its dark color and robust flavor. Stout’s distinct taste and hue come from the unique brewing process where malt is roasted. 

So, while all stouts are beers, not all beers are stouts. Remember, knowing what you’re serving is essential, especially when catering to those with dietary restrictions.

What Makes Guinness Glutenous?

The primary culprit is barley (malted and roasted barley), a key ingredient in Guinness. Along with hops, yeast, and water, this barley contains gluten, a protein off-limits for those with celiac disease or gluten sensitivities.

Malted Barley

Barley malt is the primary ingredient in Guinness— and sadly, it has tons of gluten.

Barley introduces gluten to the brew, making Guinness a no-go if you’re aiming to avoid gluten. During the brewing process, the starches in barley are converted into sugars that ferment and create the beer’s alcoholic content.

Remember, barley is a glutenous grain, so any product made from it, including Guinness, isn’t safe for those with gluten-related health concerns.


Meanwhile, Hops are a beer brewer’s best friend. It adds the zesty bitterness and captivating aroma that can make any beer a hit with the crowd! 

With no gluten content, hops are safe if you’re gluten-intolerant or have celiac disease.

So, while Guinness Stout isn’t an option for you due to glutenous grain, worry not! Many gluten-free beers have alternative grains and are delightfully flavored with gluten-free hops. 


You’ll be relieved to know that yeast, which is responsible for the fermentation process in beer, does not contain gluten. It works its magic by transforming the sugars in the beer into alcohol.

However, remember that while yeast is gluten-free, it doesn’t make Guinness gluten-free. Guinness is made from barley, a grain that contains gluten. 

Alcohol Content of Guinness
