If you’re gluten intolerant or have celiac disease, figuring out which foods and drinks are safe can be exhausting. Bourbon is made from grains, some of which contain gluten. That raises a fair question.
Is bourbon safe to drink if you’re gluten-free?
The short answer is yes. But there’s a lot of confusion out there, and not every answer you’ll find is grounded in science. This guide breaks down the facts in simple terms so you can enjoy your whiskey with confidence.
Whether you prefer bourbon, scotch, rye, or Irish whiskey, here’s what you need to know.
What Is Bourbon – And Why the Gluten Concern?
Bourbon is a type of American whiskey made primarily from corn. By law, it must contain at least 51% corn, but the rest of the grain mix often includes rye, wheat, or barley. Those extra grains are where the concern begins.
Rye, wheat, and barley all contain gluten. That’s the protein that triggers reactions in people with celiac disease or gluten sensitivity. So if bourbon includes gluten grains, doesn’t that mean the final drink has gluten in it?

It’s a reasonable question. But the answer lies in how bourbon is made, not just what goes into it.
The Science: Why Distillation Removes Gluten
Even though bourbon starts with gluten-containing grains, the gluten does not survive the distillation process.
Distillation works by heating the fermented grain mash until the alcohol turns to vapor. That vapor is then collected and cooled to create the spirit. Gluten is a protein, and proteins do not evaporate. They stay behind in the still.
That means the final product, what ends up in your glass, is just alcohol and other compounds that can travel with steam. Gluten is not one of them.
Experts agree on this. According to Coeliac UK, “all spirits are distilled and this process removes any trace of gluten.” The Celiac Disease Foundation says distilled spirits “do not contain harmful gluten peptides.”
Even if the bourbon was made using wheat, rye, or barley, the distillation process strips the gluten away. What you’re left with is a gluten-free spirit.
What the Experts Say
There is strong agreement among health experts, celiac organizations, and even government regulators: distilled whiskey is gluten-free.
The Celiac Disease Foundation confirms that bourbon and other distilled spirits are safe. They explain that even when made from gluten grains, distillation removes the gluten proteins that cause reactions in people with celiac disease.
Beyond Celiac also supports this. They note that while whiskey often begins with gluten-containing grains, the distillation process means the final product contains no gluten.
Even many whiskey brands themselves acknowledge this. Jack Daniel’s says their Tennessee Whiskey has no gluten because it is removed during distilling.
These are not vague claims. They come from scientific processes and expert review. Distilled whiskey, including bourbon, is considered safe by those who study gluten intolerance every day.
When You Might Still Need to Be Cautious
There are a few situations where you may still need to check the label—or contact the producer.
The first concern is flavored whiskey. Products like honey whiskey, cinnamon whiskey, or whiskey liqueurs often include added ingredients after distillation. Some of those additives may contain gluten or be processed in facilities that handle gluten.
The second issue is cross-contact. While rare, it’s possible that a distillery could produce both gluten-free spirits and flavored products in the same facility. If cleaning procedures aren’t strict, small traces of gluten could find their way into the final product.
The Alcohol and Tobacco Tax and Trade Bureau (TTB) allows spirits made from gluten grains to be labeled “gluten-free” only if producers take steps to prevent cross-contact after distillation.
Lastly, some people with celiac disease report symptoms after drinking whiskey. This could be due to extremely small trace amounts of gluten and the drinker’s personal sensitivity to that. If you’re unsure, it’s best to stick with brands that use only basic ingredients and no flavorings. Or reach out to the distillery directly. Many are happy to answer questions.
Gluten-Free Whiskey Brands You Can Trust
Most straight bourbons and whiskeys are gluten-free by nature of distillation. But if you’re looking for extra peace of mind, some brands stand out for their clarity and simplicity, and state that the whiskey is gluten-free on the label, or via statements.
Here are well-known whiskeys that are generally considered safe for people avoiding gluten:
- Jack Daniel’s – The company states clearly that all of its whiskeys are gluten-free, including Old No. 7, since any gluten is removed during distillation.
- Bulleit Bourbon and Bulleit Rye – Both use gluten grains but are distilled to the point where gluten is not present in the final product. Beyond Celiac includes Bulleit as a whiskey considered gluten-free by distillation.
- Wild Turkey – The company has confirmed that its bourbon contains no wheat gluten or other proteins after distillation.
- Jameson – An Irish whiskey that is triple-distilled. The company confirms it is safe for gluten-free diets.
- The Glenlivet and Glenfiddich – Both brands confirm that their scotch whiskies are gluten-free, even though they are made with barley.
If you want a whiskey made without any gluten grains from the start, you can also look at:
- Koval Millet Whiskey – Made with millet, a naturally gluten-free grain.
- James F.C. Hyde Sorgho Whiskey – Made from 100% sorghum.
These are excellent choices if you want to avoid gluten altogether, not just in the final product, but also in the production process.
Final Word: Enjoy Bourbon with Confidence
If you’re gluten-free, you can enjoy bourbon without worry. The distillation process removes gluten, even when gluten grains are used.
Experts, medical groups, and whiskey producers all agree: most straight whiskeys are safe for people with celiac disease or gluten intolerance.
To stay on the safe side, choose well-known brands with no added flavorings. Or pick a whiskey made from gluten-free grains.
Still unsure? Contact the distillery. Most are happy to answer questions.
Bourbon and other whiskeys can fit into a gluten-free lifestyle. Just sip smart.
