Is Guinness Gluten-Free?

Are you a fan of Guinness? Did you know that it’s not gluten-free? If you’re living with celiac disease or have gluten sensitivity Guinness unfortunately is not for you.

I am sorry for you, my friend, as a good tall pint of black is something hard to replace, but if you are following a wheat-free diet, it is best to avoid Guinness.

Guinness Ingredients

Guinness is brewed with various ingredients to give it its distinctive dark color and complex taste, including malted barley and roasted barley. These two types of grain contain gluten, and therefore Guinness is not gluten-free.

Furthermore, the presence of hops, yeast, and nitrogen in the brewing process can lead to cross-contamination from other grains containing gluten. This means that even if some beers do not intentionally source their ingredients from a particular source that includes gluten-containing grains, traces of such grains could still be present via unintentional cross-contamination during transport or storage processes.

Cross-Contamination Risk

While consuming any food or drink as part of a gluten-free diet, it is important to be aware of potential sources of cross-contamination.

When it comes to beer and other alcoholic beverages, gluten exposure can come from ingredients used in brewing itself (such as wheat) and during the serving process where there may be shared taps containing both gluten-containing and gluten-free beers.

Gluten Content In Guinness

Generally, a pint of Guinness has a gluten level of 20 parts per million (ppm) or higher when tested using an antibody-based assay that looks for barely-related gliadin proteins in foods; this is much higher than many other beers brewed without wheat or barley.

Can People With Celiac Disease Drink Guinness?

The answer to this question is, unfortunately, no. People with Celiac disease cannot drink Guinness due to its high gluten content and the risk of cross-contamination.

Even though Guinness does not officially contain gluten, it includes barley protein called hordein which can have a triggering effect on individuals sensitive to this kind of protein.

During the brewing process, as mentioned above, cross-contamination typically occurs, which leads to trace amounts of gluten in Guinness, even if it is not listed as an ingredient on the label.

This small amount can be enough to cause damage in people who suffer from Celiac disease or other related disorders because they cannot digest this type of wheat protein when consumed.

Beer Alternatives For Gluten-Sensitive Individuals

For those with gluten sensitivities, there may be a few suitable beer alternatives, including some gluten-free stouts and other types of alcoholic beverages such as cider and wine.

By exploring these options, people can still enjoy their drinks without triggering an immune response.

Gluten-Free Stout Options

Popular Gluten-Free Stout brands include O’Shea’s Irish stout, Breckenridge Brewery’s Celia Saison ale, Montauk Brewing Company’s Wave Chaser stout, and Ghostfish Brewing Company stout.

These gluten-free versions of the classic beer style have a distinctively bold flavor profile and creamy carbonation that makes them enjoyable for all beer lovers – from novice drinkers to longtime craft enthusiasts.

Gluten-free stouts typically contain no more than 20 parts per million (ppm) of gluten according to food standards created by the United States Food & Drug Administration (FDA).

This is below what is considered safe for people with celiac disease or extreme sensitivities to gluten intake; some brews may even contain less than ten ppm if produced under strict conditions.

Other Gluten-Free Beers

Gluten-free beers are growing in popularity as more people are on gluten-free diets for medical or dietary reasons. Gluten-free beer is made without wheat, barley, rye, or oats, all containing the protein gluten.

1. The most common ingredients used to make gluten-free beer are corn, rice, buckwheat, and sorghum.

These alternatives provide a unique flavor profile and a slight bitterness that some consumers like better than traditional beers with gluten.

2. Sorghum is one of the most popular grains used in gluten-free brewing due to its low cost and ability to ferment faster.

3. Glutenberg uses mostly millet and sorghum combined with hops to balance taste and texture while creating a beer experience similar to other dark ales.

4. Omission offers several different types of beer crafted from millet and sorghum with no bitter aftertaste that many other beers present when using these alternative ingredients.

5. New Belgium Glutiny is another popular brand made from specialty malts combined with hopped extract for an easy drinking experience and full bodied flavor without being overpoweringly hoppy as some other craft beers can be .


The answer to the question of whether or not Guinness is gluten-free is “no”. The iconic Irish stout beer contains gluten from malted barley, and as such it should be avoided by those with celiac disease or other forms of gluten intolerance.

Further, cross contamination during the production process further increases the risk that drinking Guinness could lead to health complications for those with sensitivities.

For individuals looking for alternatives to traditional beer options, there are plenty of great tasting gluten-free beers available on the market from variety of producers both large-scale and boutique.

Additionally, ciders (berry and apple beverages) have become increasingly popular in recent years as substitutes for beer that provide alluring flavors without compromising dietary restrictions.
