Gluten-Free Beer vs “Gluten-Removed”: Why Europe and America Disagree

Two beers sit side by side in the fridge. One is brewed from sorghum or rice. The other started as ordinary barley beer and had enzymes added to break the gluten down. In the EU both may legally carry the words gluten-free. In the United States, only the first one may.

That isn’t a mistake by either regulator. It’s a genuine, unresolved scientific disagreement — and if you drink beer, it’s worth understanding, because the label alone won’t tell you which camp a bottle belongs to unless you know what to look for.

The two kinds of gluten-free beer

• Naturally gluten-free beer is brewed from grains that never contained gluten — sorghum, rice, millet, buckwheat. There’s no gluten in it at any stage. Nobody disputes these.
• Gluten-removed beer (also sold as gluten-reduced or crafted to remove gluten) starts as normal barley beer. An enzyme is used to chop the gluten proteins into much smaller fragments. This is the one the argument is about.

Why testing beer is genuinely hard

Beer is a fermented, hydrolysed product, which means its proteins arrive at the lab already broken apart. The standard sandwich R5 ELISA test looks for a shape it can recognise — and once gluten has been fragmented, that shape may no longer be there to find. A low reading can therefore mean “very little gluten” or it can mean “plenty of fragments the test can’t see”.

Codex, and the European coeliac umbrella body AOECS, address this by requiring the competitive R5 ELISA for fermented products, which is designed to pick up the broken-down form. The open question — the whole debate in one sentence — is whether even that test catches everything that matters to a coeliac gut.

Where the two sides have landed

In the United States, the FDA’s position is that a beer may only be labelled gluten-free if it was made from inherently gluten-free ingredients. Barley-based ones must instead say gluten-reduced or crafted to remove gluten. American coeliac organisations go further: Beyond Celiac and the Celiac Disease Foundation both report the current US consensus as gluten-removed beers not yet being established as appropriate for people with coeliac disease. That view leans on a 2017 study in which blood samples from some coeliac participants showed an immune response to gluten-removed beer, while none responded to naturally gluten-free beer.

In the EU and UK, a barley-based beer may be labelled gluten-free if it tests at or under 20 ppm by the competitive method. AOECS still permits its Gluten-Free Trademark on such beers, and its position paper is deliberately measured: on current evidence, it says, one cannot conclude that gluten-free beers are unsuitable for coeliacs — and it explicitly states that it wants to help people make informed decisions rather than create unnecessary fears. Coeliac UK likewise recognises both types.

There’s a further wrinkle worth knowing, because it cuts against the alarming reading: one study found that the peptides capable of provoking a response were drastically reduced after simulated digestion in the stomach and small intestine. A 2024 review summed the whole field up honestly — on current knowledge it remains difficult to say definitively either way.

How to tell them apart on a real label

This is the practical part, and it’s easier than the science suggests:

• In the EU and UK: a gluten-removed beer made from barley must, under allergen law, still declare “contains barley”. So a beer marked gluten-free with a barley declaration is the enzyme-treated kind; a gluten-free beer with no gluten-cereal declaration is naturally gluten-free.
• In the US: the wording does the work — gluten-reduced or crafted to remove gluten means barley-based; gluten-free means inherently gluten-free grains.
• The AOECS Gluten-Free symbol (crossed grain with an alphanumeric code) means the product was verified against the AOECS standard — a stronger signal than the words alone.

Our own take, and it is only a take: if you are newly diagnosed, especially sensitive, or simply don’t want to think about it, naturally gluten-free beer sidesteps the entire argument. If you’ve been drinking a labelled gluten-free barley beer in Europe without trouble, the European authorities are not telling you to stop. Either position is defensible right now, which is exactly why we’d rather show you the split than pretend there’s a settled answer.

While we’re here: maltodextrin is not the villain

A related scare worth retiring. Maltodextrin appears on countless seasoning and snack labels, and its name makes people think of malt — and therefore barley.

In fact, even wheat-based maltodextrin is fine. It’s processed so thoroughly that the gluten is gone, and EU law reflects that: Annex II of Regulation (EU) No 1169/2011 exempts wheat-based maltodextrins, wheat-based glucose syrups and dextrose, and barley-based glucose syrups from allergen declaration entirely. That exemption came from EFSA assessments concluding these ingredients are unlikely to cause an adverse reaction in people with coeliac disease. Coeliac UK lists the same exemptions.

So if a seasoning contains gluten, maltodextrin almost certainly isn’t the reason. The things actually worth scanning for are wheat flour added as a bulking or anti-caking agent, and barley malt extract — which is not exempt and must be declared.

The short version

• Naturally gluten-free beer: no controversy.
• Gluten-removed barley beer: permitted and trademarked as gluten-free in Europe, not permitted to use the words in the US, and US coeliac bodies advise against it. The testing science is genuinely unsettled.
• Read for “contains barley” (EU/UK) or the words gluten-reduced (US) to tell which is which.
• Maltodextrin, even from wheat, is not the problem. Wheat flour and barley malt extract are.
