How do you know if the tequila in your glass is authentic?

The key lies in the understanding that authentic tequila must be made from blue agave (Agave tequilana Weber) grown in some specific Mexican states. This is not simply a preference, it is a strict requirement enforced by Mexican law and overseen by the Consejo Regulador del Tequila (CRT).

You will need to look for several critical indicators on the bottle. Each authentic tequila displays a unique NOM code that allows the origin to be traced back to its specific distillery. The label must also indicate the alcohol content and clearly specify whether it is a 100% agave tequila or a mixto (containing at least 51% agave sugars). Mexican law allows mixto tequilas to contain up to 1% of permitted additives.

If you’re holding an authentic bottle, you’ll notice distinctive design elements like embossed logos and the CRT seal of approval.

The production process itself contributes to the authenticity of the tequila. It begins with harvesting agave piñas, which are then cooked to extract the sugars. These sugars undergo fermentation with yeast before being distilled to create the final alcohol. Some tequilas are aged in oak barrels, resulting in different classifications, from blanco (unaged) to extra añejo (aged for more than three years).

When examining a bottle, remember that authentic tequila should be crystal clear unless it has been aged. The liquid should not contain sediment unless it is intentionally cloudy. The bottle will usually feature unique design elements that counterfeiters find difficult to replicate, ensuring you get an authentic product.

Understanding these markers of authenticity helps you make informed choices. There are five main types of tequila: blanco, joven, reposado, añejo , and extra añejo. Each offers distinct characteristics, from the pure agave flavors of the blanco to the complex and rich notes of the extra añejo.

Remember that while all tequilas must contain at least 51% agave sugars, the most prestigious varieties are made from 100% blue agave, giving you the purest expression of this iconic Mexican spirit.
