The most important quality feature of a real tequila is the designation “100% Agave” or “100% Agave Azul”.
It guarantees that the alcohol comes exclusively from the Blue Weber Agave, without any other sugar sources such as sugar cane or corn syrup being added. Such tequilas are characterized by purer, more complex and smoother flavors. They are usually bottled directly in Mexico, which can be recognized by the label “Hecho en México”. If this information is missing and the label only says “Tequila”, it is a mixto tequila. This only contains 51 percent agave juice; the rest comes from third-party sugars, which are usually cheaper but often have a much sharper taste.
Another important feature is the NOM number (Norma Oficial Mexicana) that each bottle carries, for example NOM 1414 or NOM 1123.
This number identifies the registered distillery where the tequila was produced. Platforms like Tequila Matchmaker can be used to determine which brands come from this distillery. This is a helpful indication of seriousness and quality.
In addition, high-quality tequilas should bear the seal of the “Consejo Regulador del Tequila” (CRT) and the designation “Denominación de Origen Tequila”. These seals confirm the authenticity, origin and production according to Mexican regulations, similar to Champagne or Cognac.
The category also reveals a lot about quality and style:
- Blanco/Plata: young, clear, fresh - pure agave taste.
- Reposado: slightly matured, mild with fine woody notes.
- Añejo: 1-3 years in barrel - round, complex and warm.
- Extra Añejo: aged over three years - luxurious, soft and aromatic.
Finally, smell and taste are also crucial. A high-quality tequila smells natural, herbal and gentle, never spicy or alcoholic. Blanco tequilas exude citrus and agave freshness, reposado is reminiscent of honey and vanilla, while añejo variants show notes of caramel, spices and tobacco.
On the palate, a good tequila appears round, soft and harmonious, without burning, with a gentle, long finish.
