Understanding Gluten and Alcohol
Understanding which alcohol is not gluten-free is critical if you have celiac disease or gluten sensitivity. Gluten is a protein found in grains such as wheat, barley, and rye. Some alcoholic beverages use these grains in their production, making them unsafe for those avoiding gluten.
Fermented vs. Distilled
The production method significantly impacts whether alcohol contains gluten. Fermented beverages use grains and are not gluten-free. Distillation, on the other hand, purifies alcohol and removes gluten.
Fermented Alcoholic Beverages with Gluten
- Beer: Most beers are made from barley and/or wheat, making them not gluten-free.
- Malt Beverages: These beverages often contain barley malt and should be avoided.
- Some Sake: Some varieties of sake can include barley malt, so it's essential to check labels.
Distilled Spirits: Generally Gluten-Free
Distilled spirits are generally gluten-free due to the distillation process. However, there are exceptions.
- Vodka: Can be made from wheat, but distillation removes gluten.
- Whiskey: Usually made from barley, but the distillation process removes gluten.
- Gin: Is usually gluten-free due to distillation.
- Rum: Made from sugarcane and naturally gluten-free.
- Tequila: Made from agave and naturally gluten-free.
Potential Gluten Pitfalls
Even distilled spirits can pose a risk. Flavored varieties may contain gluten.
- Flavored Spirits: Added flavorings can contain gluten.
- Liqueurs and Cordials: Some liqueurs may contain gluten.
- Mixed Drinks: Pre-made mixes or cross-contamination in bars can introduce gluten.
- Aging Barrels: Barrels sealed with wheat paste may cause contamination.
Gluten-Free vs. Gluten-Removed Beers
It is important to understand the difference between beers labeled "gluten-free" and "gluten-removed."
- Naturally Gluten-Free Beer: Made from naturally gluten-free grains, such as sorghum, rice, millet, or buckwheat.
- Gluten-Removed Beer: Made from gluten-containing grains but treated to remove gluten. They may still contain trace amounts of gluten.
Comparison: Gluten-Containing vs. Gluten-Free Alcohol
| Feature | Common Gluten-Containing Alcohol | Common Gluten-Free Alcohol |
|---|---|---|
| Primary Source | Wheat, barley, rye | Grapes, corn, potato, agave, sugar cane, fruit |
| Production Method | Fermentation (beer, ale, stout, lager) | Distillation (spirits), Fermentation (wine, cider) |
| Gluten Content | Contains gluten from grain-based fermentation | Gluten-free; distillation process removes gluten protein |
| Safety for Celiacs | Unsafe, unless certified gluten-free alternative | Generally safe, but caution with flavored varieties, additives, and cross-contamination |
| Common Examples | Traditional beer, flavored malt beverages, sake (some types) | Wine, hard cider (check label), rum, tequila, pure vodka, gin, whiskey (post-distillation) |
Conclusion
For those on a gluten-free diet, it is important to understand which alcoholic beverages contain gluten and which do not. Distilled spirits are generally safe, while traditional beers and malt beverages should be avoided. Always check labels and be cautious with flavored versions.

Staying safe while socializing
When socializing, choose beverages that are safe for your diet. Opt for unflavored distilled spirits, wine, or gluten-free hard cider. Always ask about ingredients and potential cross-contamination.
What if you're extremely sensitive to gluten?
For those with high sensitivity, choose spirits made from naturally gluten-free sources, such as vodka from corn or potato, rum, and tequila. This minimizes any risk of gluten exposure.
The importance of reading labels
Regulations may not require detailed allergen listings on all alcoholic beverages. Always research products or choose certified gluten-free options.
