For beer lovers with gluten sensitivities or celiac disease, understanding which beers are safe to consume is essential. This comprehensive guide examines the gluten content of Guinness beer and provides the information needed to make informed choices about this iconic Irish stout.
The quick answer: Is Guinness gluten-free?
No, traditional Guinness is not gluten-free. Guinness stout and most Guinness varieties contain barley, which is a gluten-containing grain. The gluten content makes traditional Guinness unsuitable for people with celiac disease or severe gluten sensitivity.
However, Guinness has introduced some gluten-reduced options that may be suitable for those with mild gluten sensitivity (but not celiac disease). We’ll explore these alternatives later in this article.
Guinness Product | Contains Gluten? | Safe for Celiac Disease? |
---|---|---|
Guinness Draught | Yes | No |
Guinness Extra Stout | Yes | No |
Guinness Foreign Extra Stout | Yes | No |
Guinness Original XX | Yes (reduced) | No |
Guinness Zero Gravity | Yes (reduced) | No |

The history of Guinness beer
Guinness beer is not just a beverage; it’s a legacy that spans over two centuries, marked by tradition, innovation, and global influence. Let’s dive into the rich history of this iconic stout.
The beginnings in Dublin
The story of Guinness begins in Dublin, Ireland, in 1759 when Arthur Guinness signed a 9,000-year lease for the St. James’s Gate Brewery. With an initial investment of £100, Arthur Guinness started brewing ales, but it wasn’t until the 1770s that he began producing the dark beer that would become synonymous with his name.
The birth of the stout
In 1778, Guinness began brewing “Porter,” a dark beer style that originated in London. Over time, the recipe was refined and became known as “stout porter” due to its robust flavor and strength. By the 1820s, Guinness had stopped brewing ale altogether, focusing exclusively on porter and stout.
Expansion and innovation
The 19th century was a period of significant growth for Guinness. The company expanded its operations, exporting beer to markets around the world. By the 1880s, Guinness had become the largest brewery in Ireland, producing over a million barrels of beer annually. This era also saw the introduction of innovations in brewing techniques and quality control, ensuring the consistent taste and quality of Guinness beer.
The iconic draught Guinness
In 1959, Guinness celebrated its 200th anniversary by introducing Draught Guinness. This new version of the stout featured a revolutionary dispensing system that used nitrogen gas to create a smooth, creamy head, setting it apart from other beers. This innovation not only enhanced the drinking experience but also solidified Guinness’s reputation as a pioneer in the brewing industry.
Global brand and cultural icon
Throughout the 20th and 21st centuries, Guinness has continued to grow, becoming a global brand recognized for its distinctive taste and iconic advertising campaigns. The “Guinness is Good for You” slogan and the memorable toucan mascot are just a few examples of how the brand has captivated audiences worldwide.

Understanding gluten and beer
Before diving deeper into Guinness specifically, it’s important to understand what gluten is and why it matters for beer drinkers with sensitivities.
What is gluten?
Gluten is a group of proteins found in certain grains including wheat, barley, and rye. For people with celiac disease or non-celiac gluten sensitivity, consuming gluten can trigger immune responses ranging from digestive issues to more serious health complications.
Gluten in the brewing process
Traditional beer brewing typically involves four main ingredients: water, malted grains (usually barley), hops, and yeast. The malted barley provides the fermentable sugars needed for alcohol production, but it also contributes gluten to the final product.
During the brewing process, some of the gluten proteins break down, but significant amounts remain in the finished beer. The exact gluten content can vary depending on the brewing methods and ingredients used.
Gluten content measurements in beer
The gluten content in beer is typically measured in parts per million (ppm). For a product to be labeled “gluten-free” in the United States, it must contain less than 20 ppm of gluten. In Australia and New Zealand, the threshold is even stricter at less than 3 ppm.
Gluten Classification | Gluten Content (ppm) | Suitable For |
---|---|---|
Gluten-Free | <20 ppm | Most people with celiac disease |
Gluten-Reduced | 20-100 ppm | Some with mild gluten sensitivity |
Contains Gluten | >100 ppm | People without gluten sensitivity |
Exploring the gluten content in Guinness beer
Guinness beer has been a favorite among beer lovers for its rich flavor and creamy texture. However, it’s important to consider its gluten content when making dietary choices.
Gluten content in traditional Guinness
Traditional Guinness products, including Guinness Draught, Guinness Extra Stout, and Guinness Foreign Extra Stout, are brewed using malted barley, which contains gluten. While Diageo (the company that owns Guinness) doesn’t publish exact gluten measurements, traditional beer made with barley typically contains between 1,000 and 2,000 ppm of gluten—far above the 20 ppm threshold considered safe for those with celiac disease.
Some people with mild gluten sensitivity report varying reactions to Guinness, with some claiming they experience fewer symptoms compared to other beers. This could be due to the specific brewing process Guinness uses, but without scientific testing, these reports remain anecdotal.
Guinness’s gluten-reduced options
In recent years, Guinness has introduced some gluten-reduced options like Guinness Original XX and Guinness Zero Gravity. These products use an enzyme called Brewers Clarex during the brewing process to break down gluten proteins.
However, it’s important to note that these products are considered “gluten-reduced” rather than “gluten-free.” While the gluten content is significantly lower than traditional Guinness, they may still contain enough gluten to trigger reactions in people with celiac disease.
The ingredients used by Guinness Brewery
Understanding the ingredients in Guinness helps explain why it contains gluten and contributes to its distinctive flavor profile.
Core ingredients in Guinness
Ingredient | Role in Brewing | Contains Gluten? |
---|---|---|
Malted Barley | Provides fermentable sugars and flavor | Yes |
Roasted Barley | Creates the dark color and roasted flavor | Yes |
Hops | Adds bitterness and aroma | No |
Water | Base for the brewing process | No |
Yeast | Ferments sugars into alcohol | No |
The distinctive flavor profile of Guinness comes from its carefully selected ingredients. The roasted barley brings deep, toasty notes, while the specific yeast strain used by Guinness balances the flavors perfectly. However, the presence of barley means that traditional Guinness beers contain gluten.
Gluten-free alternatives to Guinness
For those who love the rich, dark flavor of Guinness but need to avoid gluten, several gluten-free alternatives can provide a similar experience.
Commercially available gluten-free dark beers
Beer | Description | Gluten Content | Availability |
---|---|---|---|
Glutenberg Stout | A rich and dark stout that mimics the flavor profile of traditional stouts without gluten | <3 ppm (certified gluten-free) | North America, Europe |
Green’s Endeavour Dubbel Dark Ale | A dark ale with deep flavors, suitable for those seeking a gluten-free alternative to stouts | <5 ppm (certified gluten-free) | UK, US, Australia |
New Planet Brown Ale | A dark, malty beer with a hint of sweetness, crafted to be gluten-free | <10 ppm (certified gluten-free) | United States |
Ground Breaker Dark Ale | A complex dark ale with notes of chocolate and coffee | <5 ppm (certified gluten-free) | United States |
Holidaily Fat Randy’s IPA | A darker IPA with caramel notes | <5 ppm (certified gluten-free) | United States |
Homemade gluten-free stout recipe
For the adventurous home brewers, here’s a simple recipe to create a gluten-free stout that mimics some of the characteristics of Guinness:
Ingredients:
- 7 lbs gluten-free dark sorghum extract
- 1 lb roasted buckwheat (for color and flavor)
- 8 oz chocolate rice malt (for depth)
- 2 oz East Kent Goldings hops (bittering)
- 1 oz Fuggles hops (aroma)
- Gluten-free Irish ale yeast
- 1 tsp Irish moss (clarifying agent)
- Priming sugar for bottling
This recipe won’t perfectly replicate Guinness, but it offers a gluten-free alternative with similar dark, roasty characteristics that many stout lovers enjoy.
Understanding gluten sensitivity and Guinness consumption
Understanding the nuances of gluten sensitivity is key when considering whether to enjoy a pint of Guinness. Different conditions require different levels of gluten avoidance.
Celiac disease vs. non-celiac gluten sensitivity
Celiac disease is an autoimmune disorder where consuming gluten triggers an immune response that damages the small intestine. Even small amounts of gluten can cause significant harm to those with celiac disease.
Non-celiac gluten sensitivity (NCGS) is less severe but can still cause uncomfortable symptoms like bloating, abdominal pain, fatigue, and headaches. People with NCGS may have varying tolerance levels for gluten.
Gluten sensitivity reaction severity estimates
Condition | Reaction to Traditional Guinness | Reaction to Gluten-Reduced Guinness | Safe Consumption Level |
---|---|---|---|
Celiac Disease | Severe – Intestinal damage | Moderate to Severe – Not recommended | <20 ppm gluten only |
Severe Non-Celiac Gluten Sensitivity | Moderate to Severe symptoms | Mild to Moderate symptoms | <100 ppm may be tolerated |
Mild Gluten Sensitivity | Mild symptoms | Minimal to No symptoms | May tolerate occasional consumption |
No Gluten Sensitivity | No adverse reaction | No adverse reaction | No restrictions needed |
Testing your sensitivity
If you’re unsure about your level of gluten sensitivity, it’s crucial to consult with a healthcare provider before experimenting with gluten-containing products like Guinness. A proper diagnosis can help you understand your specific needs and limitations.
For those diagnosed with mild gluten sensitivity who wish to try Guinness, consider starting with a small amount and monitoring your body’s reaction. Keep in mind that symptoms can sometimes appear hours or even days after consumption.
Tips for gluten-sensitive individuals enjoying beer products
For those with gluten sensitivities who still want to enjoy beer, here are some practical tips and alternatives to consider.
Reading beer labels effectively
When shopping for beer, look for these key terms:
- Certified Gluten-Free: Made with naturally gluten-free ingredients like rice, sorghum, or millet
- Gluten-Reduced/Gluten-Removed: Made with barley but treated to reduce gluten content (may not be safe for celiac disease)
- Crafted to Remove Gluten: Similar to gluten-reduced, uses enzymes to break down gluten proteins
Remember that terms like “low-gluten” or “gluten-friendly” are not regulated and may not indicate safe products for those with celiac disease.

Industry trends
The gluten-free beer market is growing rapidly, with an estimated compound annual growth rate of 14.9% from 2021 to 2028. Major breweries are investing in gluten-free brewing technology and recipes to meet this demand.
Techniques for creating gluten-free beers have also improved significantly, with brewers using alternative grains like millet, rice, buckwheat, and sorghum to create more authentic beer flavors without gluten.
FAQs
Can celiacs drink Guinness?
No, individuals with celiac disease should not drink traditional Guinness beer. While Guinness has lower gluten content compared to some other beers, it still contains significant amounts of gluten from barley. Even Guinness’s gluten-reduced varieties are not considered safe for those with celiac disease. People with celiac disease should only consume beverages that are certified gluten-free (containing less than 20 ppm of gluten).
Can celiacs drink beer?
People with celiac disease should avoid traditional beers made with barley or wheat. However, they can safely enjoy certified gluten-free beers made from alternative grains like rice, millet, buckwheat, or sorghum. Many breweries now produce high-quality gluten-free beers specifically for those with celiac disease or gluten sensitivity.
Is Guinness made with wheat or barley?
Guinness is made with barley, not wheat. Specifically, Guinness uses malted barley and roasted unmalted barley, which gives the beer its characteristic dark color and roasted flavor profile. While Guinness doesn’t contain wheat, barley is still a gluten-containing grain that can trigger reactions in people with celiac disease or gluten sensitivity.
Is Guinness full of iron?
No, Guinness is not particularly high in iron. This is a common misconception that likely originated from old marketing campaigns that promoted Guinness as nutritious. A typical pint of Guinness contains approximately 0.3 mg of iron, which is only about 2-3% of an adult’s daily recommended intake. For comparison, a serving of spinach contains about 3-7 mg of iron.
Is Guinness O wheat-free?
Guinness 0 (their non-alcoholic version) is wheat-free but not gluten-free. Like traditional Guinness, it’s made with barley, which contains gluten. While it doesn’t contain wheat, it’s still not suitable for people with celiac disease or severe gluten sensitivity due to the barley content.
Is Guinness celiac friendly?
No, Guinness is not celiac-friendly. All traditional Guinness products contain barley, which has gluten proteins that can trigger autoimmune responses in people with celiac disease. Even Guinness’s gluten-reduced varieties are not considered safe for those with celiac disease, as they may still contain gluten levels above the 20 ppm threshold considered safe.
Why does Guinness upset my stomach?
Guinness may upset your stomach for several reasons. If you have celiac disease or gluten sensitivity, the gluten in Guinness could trigger digestive symptoms. Additionally, Guinness is relatively high in fiber from barley, which can cause digestive discomfort for some people. The beer’s acidity and carbonation might also contribute to stomach upset. If you consistently experience discomfort after drinking Guinness, consider consulting with a healthcare provider to determine if gluten sensitivity might be the cause.
What beer is best for celiac disease?
For individuals with celiac disease, the best beers are those that are certified gluten-free and made from naturally gluten-free ingredients like rice, millet, buckwheat, or sorghum. Top brands include Glutenberg, Ground Breaker, Ghostfish Brewing Company, and Holidaily Brewing. These beers are crafted to be completely free of gluten rather than just gluten-reduced, making them safe choices for those with celiac disease.
What beers are 100% gluten-free?
Beers that are 100% gluten-free include Glutenberg (all varieties), Ground Breaker Brewing beers, Ghostfish Brewing Company beers, Holidaily Brewing beers, Redbridge, Green’s (made with millet, rice, buckwheat, and sorghum), and New Planet Beer’s certified gluten-free options. These beers are made with alternative grains that naturally don’t contain gluten, rather than using processes to remove gluten from barley-based beers.
Is Heineken gluten-free?
No, traditional Heineken is not gluten-free as it’s brewed with barley malt. However, Heineken has released Heineken 0.0 GLUTEN FREE in some markets, which is specifically labeled as gluten-free and contains less than 10 ppm of gluten. This product is different from regular Heineken 0.0, which is alcohol-free but still contains gluten.
Is Corona beer gluten-free?
No, Corona is not gluten-free. While some tests have shown that Corona may contain lower levels of gluten than other beers (possibly due to the brewing process and ingredients), it is still made with barley and contains enough gluten to potentially cause reactions in sensitive individuals. Corona has not been certified as gluten-free and should be avoided by those with celiac disease.
Is beer higher in gluten than bread?
Generally, beer contains less gluten than bread by volume. A slice of wheat bread typically contains about 4,000-5,000 ppm of gluten, while most beers contain between 1,000-2,000 ppm. However, this doesn’t make beer safe for people with celiac disease or severe gluten sensitivity, as these levels are still far above the 20 ppm threshold considered safe. Additionally, liquid gluten may be absorbed differently than solid gluten, potentially affecting sensitivity.
Is Yuengling gluten-free?
No, Yuengling is not gluten-free. Yuengling beers are brewed with barley malt, which contains gluten. Currently, Yuengling does not offer any gluten-free or gluten-reduced beer options in their product line. People with celiac disease or gluten sensitivity should avoid Yuengling beers.
Do IPAs have gluten?
Yes, traditional IPAs contain gluten as they are typically brewed with barley and sometimes wheat, both of which contain gluten. In fact, IPAs often have higher gluten content than lighter beers because they use more grains to achieve higher alcohol content and stronger flavors. There are gluten-free IPAs available from specialized breweries that use alternative grains like millet and rice instead of barley.
Are white claws gluten-free?
Yes, White Claw Hard Seltzers are gluten-free. They are made from a base of fermented sugar rather than fermented grains, making them naturally gluten-free. White Claw is also marketed as gluten-free and is generally considered safe for people with celiac disease or gluten sensitivity. The alcohol in White Claw comes from fermented sugar cane, not from gluten-containing grains.
Is Coors Edge gluten-free?
No, Coors Edge is not gluten-free. While it is a low-alcohol beer (0.5% ABV), it is still made with barley malt, which contains gluten. Coors does not market Edge as gluten-free or gluten-reduced, and it should be avoided by those with celiac disease or gluten sensitivity.
Is there gluten in vodka?
Most vodka is considered gluten-free, even when made from gluten-containing grains like wheat or rye. This is because the distillation process effectively removes gluten proteins. However, some extremely sensitive individuals may react to grain-based vodkas. For those with severe sensitivity, vodkas made from potatoes, grapes, or corn are available and are naturally gluten-free. Always check for added flavors or ingredients after distillation that might contain gluten.
Can beer trigger celiac disease?
Beer cannot cause or trigger celiac disease itself, as celiac disease is an autoimmune condition with a genetic basis. However, consuming beer that contains gluten can trigger symptoms and intestinal damage in people who already have celiac disease. For those with the genetic predisposition to celiac disease, consuming gluten (from any source, including beer) may activate the condition, but the beer itself is not the cause.
What alcohol can I drink with celiacs?
People with celiac disease can safely consume many types of alcohol, including:
-
- Wine (red, white, and sparkling)
- Distilled spirits like vodka, gin, whiskey, and rum (even those made from gluten-containing grains, as the distillation process removes gluten)
- Certified gluten-free beers made from rice, millet, sorghum, or buckwheat
- Hard ciders (check for malt additions)
- Tequila (made from agave)
- Hard seltzers that are labeled gluten-free
Always check for added flavorings or ingredients that might contain gluten, particularly in flavored spirits or pre-mixed drinks.
Do IPAs have less gluten?
No, IPAs typically do not have less gluten than other beer styles. In fact, they often contain more gluten because they use larger amounts of malted barley to achieve higher alcohol content and stronger flavors. The intense hopping process characteristic of IPAs does not reduce gluten content. Some breweries produce gluten-reduced IPAs using enzymes to break down gluten proteins.
