The tequila aisle can be an overwhelming place. As the fastest-growing spirit category in the United States, according to the Distilled Spirits Council, bottles of the agave-based drink are multiplying on store shelves, making it increasingly difficult to differentiate quality. Add to this the complexity of regulations around sugar content and additives and discerning what’s inside each bottle becomes a daunting task.
Thankfully, every bottle of tequila features a crucial detail that acts as a window into its production: a four-digit code known as the NOM, which stands for Norma Oficial Mexicana. Assigned by the Mexican government, this code is part of official regulations ensuring that the tequila adheres to strict standards. These include its production within five designated Mexican states and the exclusive use of blue weber agave, among other requirements.
The NOM serves as an assurance that tequila is authentic and has been vetted for compliance. More importantly, it identifies the distillery where the tequila was produced. While there are thousands of tequila brands, only around 140 certified distilleries exist, meaning some brands share the same production facilities. A quick online search of a bottle’s NOM can unveil valuable insights about the distillery and its production practices.
How to Decode Your Tequila’s NOM
Locating and researching a tequila’s NOM can lead to fascinating discoveries. Many major distilleries have web pages dedicated to their NOM codes, allowing consumers to verify the producer of their bottle. While tequilas with identical NOM codes may share similarities due to common production origins, differences in aging processes, source ingredients, and additives mean the flavor profiles can still vary.
For a deeper dive, specialized databases like Tequila Matchmaker offer comprehensive information about a bottle’s production. By entering the NOM code, consumers can uncover details about extraction methods, barrel choices, and even water sources, as well as verify whether the tequila is made from 100% agave. Whether you prefer traditional tahona extraction or copper pot distillation, the NOM can help connect your preferences to the right bottle.
In general, distilleries tied to fewer brands tend to produce more artisanal, small-batch tequilas — often celebrated for their craftsmanship. For buyers seeking high-quality tequila without additives, the NOM can be a guiding beacon in selecting bottles that showcase authentic Mexican heritage and terroir.
This four-digit number not only provides transparency but also enriches the tequila experience, offering a deeper appreciation of the spirit’s origins and production journey. Next time you’re navigating the tequila aisle, let the NOM number lead the way to your perfect pour.
