Gluten-Free Beer: How It’s Made and What the Risks Are

Giving up beer is often one of the lamentable sacrifices of a celiac diagnosis. Traditional beer is brewed from malted barley, a grain packed with gluten. Unlike distilled spirits (like whiskey or vodka) where the distillation process removes gluten proteins, the fermentation process in beer leaves the gluten intact.

Fortunately, the market has exploded with alternatives. However, not all beers sold in the "gluten-free" section are safe for everyone. There is a critical distinction between two types of brewing processes.

1. Naturally Gluten-Free Beer

This is the safest option. These beers are brewed using grains that naturally contain zero gluten, such as:

• Sorghum
• Rice
• Millet
• Buckwheat
• Corn

Because no wheat, barley, or rye ever enters the brewing tank, there is no risk of gluten presence (assuming dedicated equipment is used). These beers are permitted to be labeled "Gluten-Free" without qualification.

2. Gluten-Removed (or Gluten-Reduced) Beer

This category is where the confusion—and risk—lies. These beers are brewed with barley.

To reduce the gluten, brewers add an enzyme during fermentation that breaks down the gluten protein chains into smaller fragments. The goal is to break them down enough that standard lab tests cannot detect them.

Why Celiac Organizations Don't Recommend "Gluten-Removed"

Major celiac advocacy groups and experts strongly advise people with celiac disease to avoid "gluten-removed" beers. Anecdotal evidence suggests many celiacs still react to them.

Furthermore, in many countries (including the U.S.), these products cannot legally be labeled "Gluten-Free." They must state they are "processed to remove gluten," often with a disclaimer that gluten content cannot be verified.
