Understanding Gluten in Traditional Lager
Gluten is a protein found in grains like wheat, barley, and rye, which are foundational to most traditional beer recipes. During the brewing process, the grains are malted and fermented to produce the beer's sugars and alcohol. Unfortunately for individuals with coeliac disease or gluten sensitivity, this process transfers gluten from the grain into the final product. While lagers generally contain less gluten than some other beer styles, like wheat beers, the amount is still significant enough to cause a reaction in sensitive individuals. For this reason, a regular, traditionally-brewed lager is not a safe choice for someone strictly avoiding gluten.
The Brewing Process and Gluten Content
In standard lager production, malted barley is the primary grain used. This ingredient contains a notable amount of gluten. While some gluten is broken down during fermentation, enough remains to exceed the international standard for a 'gluten-free' label, which is set at less than 20 parts per million (ppm). For example, a 2013 study found the average lager contains around 63 ppm of gluten, far above the safe limit for coeliacs. This is why relying on an unlabeled lager to be low in gluten is a risk for anyone with an intolerance.
The Rise of Gluten-Free Lagers
With the increase in coeliac diagnoses and growing consumer awareness, the market for gluten-free products has expanded significantly. This includes beer, with many breweries now offering certified gluten-free lager options. These are produced in one of two main ways, offering safe alternatives for those who need or choose to avoid gluten.
Naturally Gluten-Free vs. Gluten-Reduced Lagers
It is crucial for consumers to understand the distinction between the two types of gluten-free beer available on the market. Both are designed to be safe for gluten-avoiders, but the production method and residual risk vary.
Naturally Gluten-Free Lagers
These beers are brewed from the start using naturally gluten-free grains or pseudo-grains. Common alternatives to barley include:
- Rice
- Sorghum
- Millet
- Buckwheat
- Quinoa
By completely avoiding gluten-containing ingredients, the final product contains no gluten. For individuals with a severe sensitivity or coeliac disease, this is the safest option as it eliminates the risk of residual gluten.
Gluten-Reduced Lagers
This type of lager is brewed using traditional ingredients, including barley, and then treated with an enzyme, such as Brewers Clarex®, during fermentation. This enzyme breaks down the gluten proteins into smaller fragments. The finished product must then be tested to confirm the gluten level is below 20 ppm to be labeled 'gluten-free' in many countries, though the beer label may still declare 'contains barley'. Some with severe gluten intolerance may still react to these small fragments.
Comparison of Gluten-Free and Gluten-Reduced Lagers
| Feature | Naturally Gluten-Free Lager | Gluten-Reduced Lager |
|---|---|---|
| Starting Grains | Millet, rice, sorghum, etc. | Barley and/or wheat |
| Gluten Removal Process | None required; gluten is absent from ingredients | Enzyme (e.g., Clarex) added during fermentation |
| Gluten Content | 0 ppm | Under 20 ppm |
| Safety for Coeliacs | Generally considered the safest option | Not universally guaranteed safe for those with severe coeliac disease |
| Taste Profile | Can differ noticeably from traditional lager | Often closer in taste to a traditional lager, as it starts with barley |
| Labeling | Labeled 'Gluten-Free' | Labeled 'Gluten-Free' (subject to regional law), but may state 'contains barley' |
Identifying a Safe Lager
If you need to avoid gluten, checking the label is your most important step. Many breweries clearly mark their products to indicate their gluten-free status, often with a certified symbol. Look for clear labeling such as 'Certified Gluten-Free' or 'Gluten-Free'. For gluten-reduced beers, the label may also specify 'crafted to remove gluten' or 'gluten-reduced'.
Specific Brands to Look For
The gluten-free beer market has grown, offering more options than ever before. Some notable gluten-free lagers include:
- Estrella Daura Damm
- Peroni Nastro Azzurro Gluten Free
- Mongozo Gluten Free Premium Pilsner
- Green's Lager
- SkinnyBrands Lager
Conclusion
In conclusion, the short answer to "Does lager beer have gluten?" is yes, if it is a traditional lager brewed with barley. However, the expanding market of specialized beverages means that gluten-avoiders have plenty of safe options. By understanding the distinction between naturally gluten-free and gluten-reduced lagers, and carefully reading product labels, you can confidently choose a crisp, refreshing beer that suits your dietary needs. For those with coeliac disease or high sensitivity, naturally gluten-free beers are the recommended choice to eliminate risk.
Disclaimer
It is essential to consult with a medical professional or a qualified dietitian before making significant dietary changes. Individuals with coeliac disease, in particular, should exercise caution with any products not explicitly certified as safe.

Key Takeaways
- Traditional Lager Contains Gluten: Most lagers are brewed with malted barley, a gluten-containing grain, making them unsafe for a gluten-free diet.
- Certified Gluten-Free Options Exist: Many breweries produce lagers specifically for the gluten-free market, using safe ingredients or special processes.
- Know the Difference: There are two types: naturally gluten-free (made with non-gluten grains) and gluten-reduced (made with barley but treated to reduce gluten content).
- Check the Label Carefully: Always look for a clear 'Gluten-Free' certification on the product label, especially if you have a severe sensitivity.
- Lagers Have Lower Average Gluten: While still unsafe for coeliacs, lagers typically contain less gluten than heavier beers like ales or stouts, but this varies.
- Risk of Cross-Contamination: For the most sensitive individuals, beers made in a facility that also processes gluten-containing products may carry a risk.
FAQs
Q: What is the main source of gluten in lager? A: The main source of gluten in traditional lager is malted barley, a key ingredient used during the brewing process.
Q: How is gluten-free lager made? A: Gluten-free lager is made in two primary ways: either by using naturally gluten-free grains like rice or millet, or by using an enzyme like Brewers Clarex to remove gluten from a traditional barley brew.
Q: Is a gluten-reduced lager safe for someone with coeliac disease? A: While gluten-reduced lagers test below the 20 ppm legal threshold for a 'gluten-free' label, they are made with barley, and some individuals with severe coeliac disease may still react to the broken-down gluten proteins. Naturally gluten-free varieties are the safest option.
Q: Can I tell if a beer is gluten-free just by looking at it? A: No, you cannot determine if a beer is gluten-free by its appearance. You must always check the product label for certification or specific 'gluten-free' declarations.
Q: Do all light-colored lagers have less gluten? A: While clearer, blonder beers may sometimes have lower gluten content than dark, heavier beers, this is not a reliable rule. The only way to be certain is to check the label for certification.
Q: Are there any popular gluten-free lager brands? A: Yes, brands like Estrella Daura, Peroni Nastro Azzurro Gluten Free, and Mongozo Premium Pilsner are examples of well-known gluten-free lagers available on the market.
Q: Do other types of alcohol contain gluten? A: Most distilled spirits and wines are naturally gluten-free, but always check labels for additives. Ciders, made from apples, are also a safe option.
Q: Why is gluten content measured in parts per million (ppm)? A: Gluten content is measured in parts per million to quantify the minute amounts of residual gluten in food and beverages. The internationally recognized standard for a 'gluten-free' product is 20 ppm or less.
