Understanding the Distillation Process
The question of whether a spirit made from a gluten-containing grain, such as wheat, can be gluten-free is a common point of confusion for consumers with celiac disease or gluten sensitivity. The key to understanding this lies in the process of distillation. Distillation is a purification method that separates alcohol from other components in a fermented liquid by leveraging their different boiling points.
How Distillation Works to Remove Gluten
The process begins with a fermented mash, which for Wheatley Vodka includes wheat and other grains. This mash contains gluten proteins, which are large and heavy. When the mash is heated in a still, the alcohol vaporizes at a lower temperature than water and, critically, much lower than the large, non-volatile gluten proteins. As the alcohol vapor rises, the gluten proteins are left behind in the residual mash. The vapor is then condensed back into a highly purified liquid spirit, which is free of these proteins.
Both the U.S. FDA and TTB recognize that this process is so effective that even spirits made from gluten-containing grains are considered gluten-free. This is why pure, unflavored vodkas are generally regarded as safe for those avoiding gluten.
Wheatley Vodka: The Buffalo Trace Product
Buffalo Trace's vodka offering is called Wheatley Vodka, named after Master Distiller Harlen Wheatley. It is made with wheat and other grains and is distilled a total of ten times before being triple-filtered. The distillery explicitly confirms that Wheatley Vodka is gluten-free.
Ingredients and Production
- Base: Wheat and other grains.
- Distillation: 10 times in a micro-still.
- Filtration: Triple-filtered.
- Water: Pure Kentucky limestone water is used for proofing.
- Gluten Status: The distillery confirms that despite using wheat, the distillation process removes the gluten, making it safe for consumption by those with gluten sensitivities.
Navigating the Nuances for Sensitive Individuals
While the science of distillation supports that pure, distilled spirits are gluten-free, some individuals with celiac disease report sensitivity to grain-based vodkas. This may be due to personal sensitivity or, more likely, issues with cross-contact or post-distillation additives.
Concerns about Post-Distillation Additives and Cross-Contact
- Flavored Vodkas: For flavored versions, additives like flavorings or sweeteners are introduced after the distillation process. These can potentially contain hidden gluten. For this reason, individuals with celiac disease should be extremely cautious with flavored vodkas unless they are explicitly labeled gluten-free.
- Cross-Contact: Another, albeit less common, concern is cross-contact during bottling or storage. The Buffalo Trace distillery also produces bourbons, many of which use barley and rye. While reputable facilities implement strict protocols to prevent contamination, the potential for cross-contact, however small, may be a concern for highly sensitive individuals. Sazerac, the parent company of Buffalo Trace, notes on their nutrition page that they make no claims about the gluten-free nature of products unless specifically labeled.

| Label Claim | Certified gluten-free. | Certified gluten-free by GIG. | Naturally gluten-free. |
Naturally Gluten-Free Vodka Alternatives
For those who prefer to avoid any grain-based spirit, even if distilled, there are many excellent vodka options made from naturally gluten-free ingredients. These include:
- Potato-Based Vodkas: Brands like Chopin and Boyd & Blair create vodkas known for their creamy texture.
- Corn-Based Vodkas: Options like Tito's are made entirely from corn, offering a clean, slightly sweeter taste.
- Grape-Based Vodkas: Ciroc is made from French grapes, giving it a crisp, smooth finish.
- Sugar Cane or Beet-Based Vodkas: Various brands use these ingredients to create gluten-free spirits.
Conclusion: Making an Informed Choice
For the vast majority of people following a gluten-free diet, Buffalo Trace's Wheatley Vodka is a safe and suitable choice, as the distillation process effectively removes the gluten proteins from its wheat base. This is in line with the scientific consensus and regulatory stances in the United States and other countries. However, the crucial distinction is that this applies only to the pure, unflavored spirit. For flavored varieties, the risk of gluten reintroduction through additives exists, necessitating careful label scrutiny. Highly sensitive individuals or those who prefer to completely avoid any grain-based spirits may find greater peace of mind with vodkas made from naturally gluten-free ingredients like corn, potatoes, or grapes. Ultimately, understanding the science behind distillation empowers you to make a confident decision that aligns with your dietary needs.
It is recommended to consult with a healthcare professional regarding specific dietary needs, especially for those with celiac disease. For additional information on gluten-free living and celiac disease, please visit reputable sources like Beyond Celiac.
