In order to protect Tequila there are many regulations in place that ensure quality, production and the fact that it belongs to Mexico. The regulations I’ve listed below are in my opinion some of the most important ones, however there are many more.
The Norma Oficial Mexicana (NOM) specifies the official standards that must be kept for any product to be named Tequila, which is then certified by the Consejo Regulador del Tequila (CRT).
An important rule are the categories which refer to the content of agave in each bottle. To be classed as Tequila this has to be a minimum of 51%, meaning the other 49% can be additives, sugars etc and may be sold in bulk to then be bottled outside of Mexico – These commonly known as ‘Mixto Tequla’. The way to spot these are if they don’t state ‘100% agave’ on the label and can usually be found on supermarket shelves wearing little sombreros!
The other category is ‘100% agave Tequila’ are premium Tequilas that are exclusively bottled in Mexico and strictly monitored by the CRT. These are the ones you should be looking for!
The ABV is also regulated in the NOM which states it must be between 35% and 55%.
