Tequila, a distilled spirit made primarily from the blue agave plant, is naturally gluten-free. Gluten is just a protein within wheat, barley, and rye—none which are used in the production of authentic tequila. Since tequila is made from agave, a form of succulent native to Mexico, it has no ingredients that will introduce gluten into the final product. This causes it to be a safe and enjoyable alcoholic choice for people that have celiac disease or non-celiac gluten sensitivity. The key, however, is choosing tequila produced from 100% agave, as mixed varieties may contain additives that aren't gluten-free.
Not all tequila is created equal, especially when it comes to gluten sensitivity. Pure tequila, defined as “100% agave,” is considered safe for people avoiding gluten because it has only fermented and distilled agave sugars. However, some lower-quality tequilas, often called “mixto,” include other sugars such as cane sugar or corn syrup, and occasionally grain-based additives. While the tequila gluten free process should technically remove gluten, cross-contamination or flavorings added after distillation can pose a risk. Therefore, individuals with gluten intolerance should always decide for 100% agave tequila to make certain safety.
The distillation process is one of many reasons tequila is generally considered safe for gluten-free diets. Distillation is a technique of purifying liquids by heating them into vapor and then cooling them back to liquid form, effectively removing proteins like gluten, which don't vaporize. Even when tequila were stated in facilities that handled grains (which most are not), the gluten would typically be eliminated during distillation. Nevertheless, flavored or infused tequilas may have added ingredients post-distillation, which may reintroduce gluten. It's always wise to verify the ingredient list or consult the manufacturer.
While pure tequila is gluten-free, flavored or infused varieties could be problematic for those avoiding gluten. Brands often add flavorings, sweeteners, or colorants to interest broader markets. These additives aren't always disclosed in detail and may include hidden sources of gluten, especially if based on grain-based alcohols or syrups. As an example, creamy or dessert-inspired flavored tequilas could contain barley malt or wheat derivatives. As a precaution, gluten-sensitive consumers should avoid flavored tequilas unless the brand clearly states it's certified gluten-free.
For individuals with severe gluten intolerance or celiac disease, certification is an extra layer of safety. Some tequila brands seek gluten-free certification from third-party organizations that test the product and the production facility. This certification ensures that the tequila meets stringent standards for gluten absence—typically significantly less than 20 parts per million (ppm), that is the FDA's threshold for gluten-free labeling. Without all gluten-free tequila is certified, choosing a professional brand gives peace of mind to consumers who're particularly sensitive to cross-contamination.
