How can a beer be gluten-free but still have wheat and barley?
For gluten-sensitive beer lovers, the idea of gluten-free beer made with wheat or barley might seem contradictory. Here's how it works:
-
Two Methods:
- Enzymatic Treatment: Enzymes like Clarity Ferm break down gluten in traditional grains (e.g., wheat, barley) into smaller fragments, reducing gluten to safe levels (below 20 ppm).
- Alternative Grains: Beers brewed with naturally gluten-free grains like sorghum, rice, millet, or buckwheat avoid gluten entirely.
-
Two Types of Gluten-Free Beer:
- Gluten-Free: Made with grains that naturally lack gluten and meet strict safety standards for celiac disease.
- Gluten-Reduced: Made with traditional grains but treated to lower gluten levels; not always safe for celiac sufferers.
-
Key Differences:
- Gluten-free beers rely on alternative grains and dedicated equipment.
- Gluten-reduced beers taste closer to traditional beer but may still contain trace gluten.
Quick Comparison:
| Feature | Gluten-Free Beer | Gluten-Reduced Beer |
|---|---|---|
| Grains Used | Sorghum, millet, rice, etc. | Barley, wheat |
| Gluten Content | < 20 ppm | May exceed 20 ppm |
| Safety for Celiac | Safe | Not recommended |
| Taste Profile | Unique flavors | Similar to traditional beer |
Understanding these methods and distinctions can help you choose a beer that fits your dietary needs while still enjoying great flavor.
Gluten in Beer Explained
Gluten: What It Is and Why It's in Beer
Gluten is a protein naturally found in grains like wheat, barley, and rye - key ingredients in traditional beer brewing. These grains have been staples in brewing for centuries, making gluten a natural part of most beers [1]. Understanding its role in brewing sheds light on why creating gluten-free beer comes with unique hurdles.
Here's a quick look at how traditional brewing grains stack up against gluten-free alternatives:
| Traditional Brewing Grains (Contain Gluten) | Gluten-Free Brewing Grains |
|---|---|
| Barley (most common) | Sorghum |
| Wheat | Rice |
| Rye | Millet |
| Malted Oats | Buckwheat |
| Quinoa | |
| Teff |
Gluten's Role in Brewing
Gluten affects several important aspects of beer production [2]:
- Structure: It contributes to the beer's body, mouthfeel, and how well the foam (or "head") holds up.
- Flavor: Grains like barley, which contain gluten, are responsible for the malty sweetness and rich flavors that define traditional beers [1].
- Stability: Gluten proteins help ensure the beer maintains its consistency over time [2].
Although gluten is central to traditional brewing, modern methods now allow brewers to either remove or neutralize it, making it possible to produce beer without sacrificing quality [2][3].
Science of Gluten-Free Beer
Removing or Breaking Down Gluten
Gluten is a key component in traditional beer brewing, but modern techniques allow brewers to reduce or eliminate it while maintaining the beer's quality. One common method involves enzymatic treatments, such as prolyl endopeptidases (e.g., Clarity Ferm), which break gluten proteins into smaller pieces. This process can lower gluten levels to amounts considered safe for most people with gluten sensitivities [2].
Here are two main approaches used in gluten-free beer production:
| Method | Result |
|---|---|
| Enzymatic Treatment | Reduces gluten to levels below 20 ppm |
| Advanced Filtration | Removes leftover gluten fragments |
Once the gluten is reduced or removed, brewers must meet strict labeling requirements to ensure the beer is safe for consumers.
Gluten-Free Certification and Labeling
In the U.S., the Tax and Trade Bureau of Alcohol, Tobacco, and Firearms (TTB) regulates gluten-free beer, requiring it to contain less than 20 ppm of gluten [3]. Beers labeled as "gluten-reduced" may not meet this strict threshold but undergo processes to significantly lower gluten content.
There are two main categories:
- Gluten-Free: Contains less than 20 ppm of gluten, achieved either naturally or through treatment.
- Gluten-Reduced: Treated to lower gluten levels but might not meet the under-20 ppm standard.
Some breweries skip enzymatic treatments altogether by using grains that are naturally free of gluten. This ensures compliance with the most stringent gluten-free standards and maintains the beer's quality [2].
As brewers refine their methods, the science of gluten removal continues to improve [2][4]. While certifications provide clarity for consumers, the brewing process itself is critical to ensuring safe gluten levels in the final product.
Brewing Gluten-Free Beers
Alternative Grains in Gluten-Free Brewing
Brewers craft gluten-free beers by using grains like sorghum, rice, millet, and buckwheat, which don't contain gluten. Each of these grains brings its own flavor and texture to the beer [1].
| Grain Type | Characteristics | Flavor Notes |
|---|---|---|
| Sorghum | Easily fermentable | Crisp |
| Millet | Similar to barley | Sweet |
| Buckwheat | Improves foam | Nutty |
| Rice | Provides clarity | Clean |
For example, Buck Wild Pale Ale, a 100% gluten-free beer from the Bay Area, uses a mix of buckwheat and millet. This combination balances a nutty richness with hop bitterness, creating a well-rounded flavor [5].
Adjusting Brewing Techniques for Gluten-Free Beers
Brewing gluten-free beer isn't just about switching grains - it also requires some adjustments to the brewing process:
- Temperature Adjustments: Gluten-free grains need precise temperature control during mashing to properly break down starches [1].
- Fermentation Tweaks: Special yeast strains are selected to work effectively with these grains [2].
- Strict Quality Standards: Breweries modify equipment and processes to keep gluten levels under 20 ppm, ensuring the beer meets gluten-free safety standards [3].
These methods make it possible for those with gluten sensitivities to enjoy a variety of beers without sacrificing taste or safety. However, it's important to understand the difference between gluten-free and gluten-reduced beers when making your choice.

Gluten-Free vs. Gluten-Reduced Beers: A Comparison
For anyone with gluten sensitivities, knowing the difference between gluten-free and gluten-reduced beers is key. While both cater to those avoiding gluten, their brewing methods and safety levels vary a lot.
Gluten-free beers are made using grains that naturally contain no gluten, such as sorghum, rice, millet, or buckwheat. These beers are brewed to maintain gluten levels below 20 ppm, meeting the safety standards for people with celiac disease [1][3].
Gluten-reduced beers, on the other hand, are brewed with traditional grains like barley or wheat. Enzymes are then added to break down gluten proteins. While this process can lower gluten levels, it doesn’t guarantee safety for those with celiac disease, as trace amounts might remain [2][4].
A standout example of a gluten-free beer is Lakefront Brewery's New Grist, which avoids enzymatic treatments entirely. Instead, they use only naturally gluten-free grains, ensuring a safe option for those with strict dietary restrictions [3].
Comparison Table: Gluten-Free vs. Gluten-Reduced Beers
| Feature | Gluten-Free Beer | Gluten-Reduced Beer |
|---|---|---|
| Grains Used | Sorghum, rice, millet, buckwheat | Barley, wheat |
| Production Method | Brewed with naturally gluten-free grains | Enzymes used to reduce gluten |
| Gluten Content | Less than 20 ppm | May exceed 20 ppm |
| Certification | Certified gluten-free | Rarely certified |
| Safety for Celiac | Safe for consumption | Not recommended |
| Taste Profile | Unique flavors from alternative grains | Similar to traditional beer |
| Production Facility | Dedicated gluten-free equipment | Standard brewing equipment |
| Cost Factors | Higher due to specialty ingredients | Lower due to traditional grains |
The key difference lies in their production and safety. Gluten-free beers require specialized equipment and ingredients to avoid cross-contamination, making them a safer choice for those with severe gluten sensitivities [2][3].
For gluten-sensitive drinkers, knowing these distinctions helps in choosing a beer that aligns with their health needs.
Conclusion: Choosing Gluten-Free Beer Wisely
Brewers use two main methods to produce gluten-free beer: brewing with naturally gluten-free grains or applying enzymes to reduce gluten levels. Knowing these approaches can help you pick a beer that suits your dietary requirements.
Tips for Gluten-Sensitive Consumers
If you have celiac disease or a severe gluten sensitivity, beers made with naturally gluten-free grains are your safest bet. Look for certifications from organizations like GFCO or CSA, and prioritize breweries that operate in dedicated gluten-free facilities.
Enzymes can lower gluten content by over 90% [2][6], but this doesn’t guarantee safety for everyone with celiac disease. Beers like Lakefront Brewery's New Grist, which rely on dedicated gluten-free equipment and ingredients, offer extra peace of mind [3].
The TTB enforces strict rules for gluten-free labeling, making it easier for you to choose wisely. If you're unsure, reach out to breweries to ask about their production methods and testing practices.
Armed with this knowledge, you can explore gluten-free beer options with confidence, even as brewing processes and enzyme use continue to raise questions.
FAQs
How is gluten-free beer brewed?
Brewers create gluten-free beer in two main ways: by using grains like sorghum, millet, and rice that naturally lack gluten, or by adding enzymes to break down gluten in traditional grains such as barley and wheat [1][2]. Each method results in a beer that's safe for gluten-sensitive individuals, though the taste may differ from conventional beers [1][2].
What enzyme removes gluten from beer?
Clarity Ferm is an enzyme that lowers gluten levels to below 20 ppm by breaking down gluten proteins into smaller fragments. While this meets FDA standards for gluten-free labeling, it may still pose risks for those with celiac disease [7][3].
These brewing approaches and tools allow consumers to choose gluten-free beers that best suit their health requirements.

How is 0.5% ABV alcohol-free?
Yes, we know it's confusing. Isn't 0.5% ABV still alcoholic? Officially, 0.5% ABV is classified as Dealcoholised.
- In fact, most things we consume daily have more than 0.5% ABV
- Burger Rolls - 1.2% ABV
- Orange Juice - 0.5% ABV
- Ripe Banana - 0.5% ABV
After more than 2 years of research, we've found that the 0.5% ABV from our natural brewing process significantly increases both flavour and mouthfeel - without spiking your blood alcohol level (BAC).
Is it really gluten-free?
Yes, IMPOSSIBREW® Enhanced Lager is gluten-free. Even though it contains wheat and barley, our beers have been third-party tested to contain less than 10 parts per million (PPM) of gluten, which meets the criteria to be listed as, and labeled gluten-free.
Does it have alcohol tax?
No. While it is true that our beers don't contain alcohol, and thus don't incur UK alcohol duty, we'd like to highlight some factors here that might be helpful in reflecting the value we provide.
- One-to-One Brewing Process: At IMPOSSIBREW, we take pride in our unique brewing techniques. Unlike other non-alcoholic beers, our products are never diluted, watered-down, or have their alcohol content removed - and some even dilute their alcoholic beers up to 5x. This means that our brewing process involves the same level of craftsmanship, time, and resources as a traditional craft beer, resulting in comparable production costs.
- Effective Nootropics: In our commitment to creating the most relaxing non-alcoholic beers, we utilise only the highest quality nootropics as our active ingredients, in safe and effectives dosages. At current alcohol tax rates for a 5% ABV beer, the cost of our nootropics more than double that. Instead of contributing the amounts as tax, why not have it contribute to the product quality itself?
- Small Scale Brewing: Currently, we operate on a smaller scale, which makes us less competitive than large, commercial brewers (often +10,000x our brewing size). As a growing business, we are passionate about our mission to create unique, high-quality non-alcoholic experiences, and we truly appreciate your support. As we continue to grow and expand our production capabilities, we look forward to passing on even more savings to our valued community!
At IMPOSSIBREW, we prioritise offering our customers an enhanced, premium, non-alcoholic beer experience by combining innovative brewing techniques, quality active nootropic ingredients, and award-winning taste. While our pricing may differ from other non-alcoholic competitors, we believe that the value proposition and unique experience our beers provide are well worth it.
At the end of the day, tasting is believing. So give it a try and let us know what you think - risk-free with our IMPOSSIBREW® Guarantee.
Who shouldn't drink IMPOSSIBREW®?
It is not recommended for pregnant or breastfeeding women, those with certain medical conditions like GI disorders or hypertension, or individuals taking specific medications such as antidepressants or blood thinners. If you fall into any of these categories, it's best to consult with your doctor first.
Ashwagandha can lead to overstimulation (i.e. restlessness) if taken alongside thyroid medication.
What is your philosophy?
For thousands of years, we had only one way to unwind together. One way to let our guards down. One way to bridge the gap between who we are and who we are with others.
Not because it was perfect. But because it was all we had.
We decided that wasn't good enough.
We exist because we believe in a world where social connection doesn't demand compromise.
Where being present with others doesn't mean being absent from yourself. Where letting go doesn't mean losing control.This isn't about removing alcohol. This is about something better.
Our Social Blend™ technology isn't an accident. It's the result of questioning everything we thought we knew about social drinking. About working with scientists to understand what we're really seeking in these moments of connection. About daring to imagine something that wasn't possible before.
We believe the greatest innovations don't just solve problems - they change how we live. They make us question why we ever settled for less.
That's what we're building. Not just a drink, but a new way forward. A future where social connection comes without compromise. Where tradition meets innovation. Where science meets ritual.
This is the future of social drinking.
