What is a NOM?
A four-digit NOM (Norma Oficial Mexicana) number appears on every bottle and lets you know which tequila producer a brand comes from. If two brands share a NOM number, they were made in the same place and might even share the same process. Visit http://KnowYourNOM.com to explore the different distilleries and the brands they produce.
