Is Bourbon Celiac Friendly? Your Definitive Gluten-Free Guide

November 27, 2025 •

3 min read

According to major celiac organizations, pure distilled spirits, including bourbon, are considered safe for individuals with celiac disease, even though they may be made from gluten-containing grains. This fact is due to the science of distillation, which removes the gluten protein from the final product.

Quick Summary

The distillation process effectively removes gluten proteins, making pure bourbon safe for most people with celiac disease. Flavored versions and cross-contamination are potential risks to consider when choosing a bottle.

Key Points

Distillation Removes Gluten: The process of distillation effectively separates and removes gluten proteins from the finished bourbon, even if it's made with gluten-containing grains.
Flavored Bourbons Pose a Risk: Added ingredients in flavored bourbons or liqueurs, introduced after distillation, may contain gluten and should be avoided.
Cross-Contamination is Possible, but Rare: While uncommon in major distilleries, cross-contact can occur, a factor the most sensitive celiacs should consider.
Choose 100% Corn Bourbon for Certainty: For absolute peace of mind, opt for bourbons made from a 100% corn mash bill, which is naturally gluten-free.
Many Major Brands Are Safe: Most pure, straight bourbons from well-known brands like Jim Beam, Maker's Mark, and Wild Turkey are widely considered safe for people with celiac disease.
Always Check Your Mixers: When making cocktails, ensure all additional ingredients, such as mixers and bitters, are also gluten-free.

The Science of Distillation: Why Pure Bourbon is Safe

For those with celiac disease or gluten intolerance, understanding how bourbon is made is key. Bourbon's mash bill often includes gluten-containing grains such as wheat, rye, or barley, in addition to the required minimum of 51% corn. However, the distillation process is crucial here. During distillation, the fermented mash is heated, and the alcohol vaporizes while the heavy gluten proteins remain behind. The collected and condensed vapor results in a pure, distilled spirit that is considered gluten-free. This is why major celiac organizations state that pure distilled spirits are safe for those with celiac disease.

Potential Risks: The Case of Flavored Bourbons

While pure, straight bourbon is generally safe, flavored bourbons and whiskey liqueurs can introduce gluten after distillation. Additives for flavor, color, or sweetness may contain gluten or be processed on shared equipment, risking cross-contact. Always check labels carefully and be mindful of all ingredients in cocktails.

The Challenge of Cross-Contamination

Though uncommon for major bourbon brands, highly sensitive individuals might consider the potential for cross-contact if a distillery also produces malt-based products on the same equipment. Contacting the manufacturer directly can provide more information on their practices.

Choosing Your Bourbon: Brands and Labeling

Many major straight bourbon brands are considered safe due to distillation. In the US, the TTB allows distilled spirits from gluten grains to be labeled 'gluten-free' under certain conditions. For extra caution, consider bourbons made from 100% corn or sorghum, which are naturally gluten-free.

Comparison of Bourbon Types


Feature	Pure, Straight Bourbon	Flavored Bourbon	100% Corn Bourbon
Gluten Source	Yes, in initial mash bill (wheat, rye, barley)	Yes, often from additives	No, naturally gluten-free
Gluten Removed?	Yes, via distillation	May be added back post-distillation	Not applicable
Celiac Friendly?	Generally considered safe	High risk; requires verification	Safest option for highest sensitivity
Labeling	May be labeled 'gluten-free' (US)	Unlikely to be labeled 'gluten-free'	Can be certified 'gluten-free'
Key Precaution	Avoid post-distillation additives	Check for gluten in added flavorings	Little to no risk

A List of Widely Considered Celiac-Friendly Bourbon Brands

Many popular bourbon brands are widely accepted as safe for those with celiac disease:

Jim Beam
Wild Turkey
Maker's Mark
Bulleit Bourbon
Woodford Reserve
Hudson Baby Bourbon (100% corn)

Conclusion

Pure, straight bourbon is generally celiac friendly because distillation removes gluten. However, be wary of flavored versions, added ingredients, and potential cross-contamination. Sticking to well-known, unflavored brands or those made from 100% corn offers peace of mind. Always check labels and be aware of all cocktail ingredients. For more information, consult resources like the Beyond Celiac Foundation.

What to Look For and How to Stay Safe

Choose pure, straight bourbon, avoiding flavored varieties.
Examine labels for added ingredients after distillation.
Consider 100% corn bourbons for maximum caution.
Consult your doctor if you have extreme sensitivities.
Research distilleries for cross-contamination practices if highly sensitive.

How to Check for Additives

While full ingredient lists aren't always required, flavorings must be declared.
Check company websites for detailed production information.
Be mindful of all cocktail components like bitters and mixers.

Frequently Asked Questions

No, because of the distillation process. Even if gluten-containing grains like wheat or rye are used in the mash bill, the distillation process removes the gluten protein, making the final product safe for most people with celiac disease.

Yes, people with celiac disease can generally drink pure, straight bourbon. Health organizations confirm that the distillation process makes spirits safe, provided no gluten is added after distillation.

While distillation is highly effective, a very small number of extremely sensitive individuals might still react to trace elements. In these cases, opting for a bourbon made from 100% corn is the safest choice.

Not necessarily. Flavorings or other ingredients added to bourbon after the distillation process can contain gluten. It is best to avoid flavored versions or check the manufacturer's information carefully.

Look for pure, straight bourbon with no added flavorings. For the highest level of assurance, choose a brand made from 100% corn, as corn is naturally gluten-free.

Yes, in the US, the TTB allows 'gluten-free' claims on distilled products, including those made with gluten grains, as long as good manufacturing practices prevent gluten from entering the finished product.

Yes, a rare risk of cross-contact exists in distilleries that process both spirits and other gluten-containing products, though this is not a widespread issue for major brands.

Yes, but be cautious. The bourbon itself is likely safe, but you must ensure all other cocktail ingredients, like bitters, mixers, and garnishes, are also gluten-free.

A 'wheated' bourbon replaces rye with wheat in its mash bill, resulting in a softer flavor. As with other straight bourbons, the distillation process removes the gluten, so it is still considered safe.
