Wondering if your favorite brew is packed with gluten? You’re not alone. In fact, traditional beer is often made from barley or wheat – both loaded with gluten!

This blog will guide you through the grainy world of beer, discussing why and how much gluten it contains, and even offering delicious alternatives for those seeking a gluten-free pint.

Understanding Gluten and its Presence in Beer

Does Beer Have Gluten Init (1)

Gluten, a protein found in grains like barley and wheat, is present in beer due to the use of these ingredients during the brewing process.

What is gluten?

Gluten is a type of protein found in many common grains such as wheat, barley, and rye. These proteins give bread its chewy texture and help it maintain its shape during the baking process. The key thing to note here is that barley – full of gluten – serves as the dominant grain used in beer production.

This means most traditional beers contain varying levels of gluten, potentially causing adverse reactions in those with certain dietary conditions like celiac disease or gluten sensitivity.

Why does beer contain gluten?

Beer contains gluten because it is traditionally made with grains such as barley, wheat, and sometimes even rye. These grains are the main sources of gluten in beer. During the brewing process, these grains go through fermentation, which helps develop the flavors and alcohol content in beer.

However, this fermentation does not eliminate or break down the gluten proteins present in these grains. As a result, when individuals with celiac disease or gluten sensitivity consume regular beer, they may experience adverse reactions due to the presence of gluten.

It’s important for those who cannot tolerate gluten to seek out alternative options such as gluten-free beers that are specifically brewed without using any ingredients containing gluten.

It’s worth noting that there are also some beers labeled as “gluten-reduced” where breweries use specific techniques to minimize the levels of gluten in their products.

Grains used in beer production that contain gluten

Beer production involves the use of various grains and additives, some of which contain gluten. Here are the grains commonly used in beer production that contain gluten:

  • Barley: Barley is one of the primary ingredients in beer and contains gluten. It provides the sugars necessary for fermentation and contributes to the flavor and body of the beer.
  • Wheat: Wheat is another grain commonly used in beer production, particularly in styles like wheat beers and hefeweizens. It also contains gluten.
  • Rye: Rye is sometimes used in specialty beers, especially those with a distinct spiciness or earthy character. It contains gluten.
  • Oats: While oats themselves do not naturally contain gluten, they often come into contact with gluten during processing. As a result, most conventional oats are not considered gluten-free. However, certified gluten-free oats can be used in specialty gluten-free beers.

Gluten-Free Beer Options

Gluten-free beers are made using alternative grains, such as sorghum or rice, to replace barley and wheat, ensuring they are safe for individuals with celiac disease or gluten sensitivity.

How are gluten-free beers made?

Gluten-free beers are made using alternative grains and ingredients that do not contain gluten. Here’s how they are produced:

  1. Start with gluten-free grains: Gluten-free beers are typically brewed using grains such as sorghum, millet, rice, buckwheat, or corn instead of barley or wheat.
  2. Mashing process: The chosen gluten-free grains are milled and mixed with hot water to extract their fermentable sugars. This process is similar to traditional beer brewing methods.
  3. Enzyme addition: To ensure proper fermentation and conversion of sugars, enzymes are added during the mashing process. These enzymes help break down complex carbohydrates into simpler forms.
  4. Hops and yeast: Gluten-free beers still use hops for bitterness and flavor, just like regular beer. Yeast is also added to initiate fermentation and convert sugars into alcohol.
  5. Fermentation: The mixture is left to ferment for a certain period, allowing the yeast to convert sugars into alcohol and create carbonation.
  6. Filtration or centrifugation: After fermentation, gluten-free beers often undergo filtration or centrifugation processes to remove any remaining traces of gluten from the final product.
  7. Testing for gluten content: To ensure compliance with labeling requirements and the safety of people with celiac disease or gluten sensitivity, gluten-free beers undergo rigorous testing to confirm that they meet the established standards for gluten content (less than 20 parts per million).
  8. Packaging and distribution: Once the beer has passed the necessary tests, it is packaged in bottles, cans, or kegs like any other beer product. It is then distributed for sale in stores or served in bars and restaurants.

Popular gluten-free beer brands

Here are some popular gluten-free beer brands that individuals with celiac disease or gluten sensitivity can enjoy:

  1. Omission Brewing Co.: Known for their gluten-removed beers, Omission Brewing offers a variety of options such as Lager, Pale Ale, and IPA.
  2. Green’s: This Belgian-style brewery specializes in gluten-free and vegan beers made from millet, sorghum, buckwheat, and brown rice.
  3. New Planet Beer Company: New Planet offers a range of gluten-free options including Tread Lightly Ale, 3R Raspberry Ale, and Blonde Ale.
  4. Daura Damm: This Spanish brewery produces a gluten-free lager called Daura Damm which is made from barley malt but considered safe for those with celiac disease due to the gluten removal process.
  5. Ghostfish Brewing Company: Focusing solely on brewing gluten-free beer, Ghostfish offers a wide variety of styles including IPAs, stouts, and fruit-infused ales.
  6. Ground Breaker Brewing: Specializing in using alternative grains like roasted chestnuts and lentils as substitutes for traditional grains containing gluten, Ground Breaker offers unique flavors in their gluten-free beers.
  7. Glutenberg: A Canadian brewery known for its award-winning gluten-free craft beers that are made from millet, corn, rice, amaranth, quinoa, and buckwheat.
  8. Brunehaut Brewery: Producing organic and certified gluten-reduced beers made from malted barley or wheat but processed to remove most of the gluten content.
  9. Two Brothers Artisan Brewing: Two Brothers offers a selection of certified Gluten-Free Prairie Path Golden Ale which is brewed with tapioca syrup as the primary fermentable sugar.
  10. Lakefront Brewery: Their New Grist Gluten-Free Pilsner is brewed with sorghum and rice extract to create a crisp and refreshing beer suitable for those with celiac disease.

Gluten-Reduced Beers

Gluten-reduced beers are brewed using techniques that break down the gluten proteins, resulting in a lower gluten content.

What are gluten-reduced beers?

Gluten-reduced beers are a popular option for individuals with gluten sensitivities or mild reactions to gluten. These beers undergo a process that reduces the gluten content, making them safer to consume for those who cannot tolerate regular beer.

The process involves using enzymes or specific yeast strains that break down the gluten proteins into smaller fragments, reducing their impact on sensitive individuals.

While these beers may still contain trace amounts of gluten, they meet the FDA’s criteria for labeling as “gluten-reduced.”


In conclusion, beer does contain gluten due to the grains used in its production, such as barley and wheat. This makes it unsafe for individuals with celiac disease or gluten sensitivity.

However, there are gluten-free beer options available that cater to those with specific dietary needs.

It is important for beer drinkers to understand the presence of gluten in their favorite beverage and make informed choices accordingly.
