The Science of Distillation: Why Wheat-Based Vodka Can Be Gluten-Free
For those with celiac disease or gluten sensitivities, the idea of a wheat-based product being gluten-free may seem contradictory. The key to this lies in the scientific process of distillation.
How Distillation Removes Gluten
During the vodka-making process, a fermented "mash" is created from grains like wheat, or other starches like potatoes. This mash contains gluten proteins if it was made from gluten-containing grains. The process then moves to distillation, where the liquid is heated. Because alcohol has a much lower boiling point than water—and significantly lower than large, heavy gluten proteins—it turns into vapor and rises. The gluten proteins, being non-volatile, are left behind in the still. This pure alcohol vapor is then collected and condensed back into a purified liquid spirit, completely free of the original gluten proteins. Grey Goose, in particular, only distills its vodka once to maintain the character of its ingredients, a process that is still sufficient for gluten removal.
Regulatory Backing for Distilled Spirits
Major health and regulatory bodies in both the U.S. and Canada recognize that pure, distilled spirits are gluten-free, regardless of their starting ingredients. The U.S. Alcohol and Tobacco Tax and Trade Bureau (TTB) updated its rules to allow spirits distilled from gluten-containing grains to be labeled as gluten-free, provided the process is clearly explained. This aligns with the understanding that the distillation process physically removes the gluten from the final product.
Unflavored vs. Flavored Grey Goose: A Critical Distinction
While the science confirms that pure Grey Goose vodka is gluten-free, the same caution cannot be applied to flavored varieties without further investigation.
The Risk with Flavored Vodkas
The risk in flavored vodkas comes from additives introduced after the distillation process. These additional ingredients—flavorings, sweeteners, or other botanical essences—could potentially contain gluten or be at risk of cross-contact during manufacturing. For example, while Grey Goose's Essence line is also advertised as gluten-free, consumers with high sensitivity or celiac disease should always verify the ingredients and manufacturing practices for any flavored spirit. It is always safer for highly sensitive individuals to stick with the pure, unflavored variety.

How to Choose the Right Vodka for Your Needs
If you have celiac disease or a high sensitivity to gluten, you have a few options to consider when selecting a vodka. The choice often comes down to your level of comfort with the distillation process.
-
Trust the Science: The most common approach is to rely on the scientifically-proven fact that pure, distilled spirits are gluten-free, even if made from wheat. This means that the original Grey Goose is a safe option. For many, this is sufficient.
-
Choose Naturally Gluten-Free Base Ingredients: If you prefer to avoid any potential risk, even in trace amounts, you can select vodkas made from naturally gluten-free sources like potatoes, corn, or grapes. Brands like Tito's (corn) or Cîroc (grapes) are popular choices in this category.
-
Look for Gluten-Free Certification: For the highest level of assurance, seek vodkas that have been certified by a reputable third-party organization like the Gluten-Free Certification Organization (GFCO). This indicates that the product has been tested to meet strict gluten-free standards. Tito's, for example, is GFCO certified.
What to Avoid
Regardless of your chosen vodka, you should exercise caution with flavored varieties and pre-made cocktails. The addition of other ingredients after distillation poses the greatest risk for gluten contamination. Always read the label or check the manufacturer's website for specific allergen information.
Conclusion
In summary, yes, pure and unflavored Grey Goose vodka is gluten free. The scientific process of distillation removes all gluten proteins, even though the spirit is made from French winter wheat. This is a fact supported by Grey Goose itself and major health organizations. However, individuals with celiac disease or high gluten sensitivity should be cautious with flavored versions, as post-distillation additives can introduce gluten risk. Ultimately, for a truly worry-free experience, consider sticking to the original unflavored variety or opting for a vodka made from naturally gluten-free ingredients and verified by a certification program.
