Tequila

Tequila is legally required to be only 51% blue agave.

Many tequilas will advertise themselves as ‘100% Blue Agave,’ but the legal requirement is 51%. Distillers are allowed to fill out the rest with a neutral spirit made from cane sugar juice, creating what is known as a “mixto” tequila.
If bottle say 100% blue than it is made by 100% blue agave if not mentioned on bottle than 51% blue agave rest 49% mix

There are around 295 different agave species but only one may can be used for this drink. Mezcal and Pulque are beverages made from other species of agave that are not Tequila’s. So this would be the main difference between tequila, mezcal and pulque.

Tequila is a Denomination of Origin (DOT) product, which gives the drink the exclusiveness of being elaborated in certain regions of Mexico only, those that are among the denomination of origin. These are: Jalisco, part of Nayarit, part of Michoacán, part of guanajuato and part of Tamaulipas

The Cuervo family, who everyone now knows and loves, began commercially distilling tequila in 1758, followed later by the Sauza family in 1873
So the 1st to distill tequila is Jose cuervo

In a move to take ownership of the term “tequila,” the Mexican government declared the term as its intellectual property in 1974. This made it necessary for tequila to be made and aged in certain areas of Mexico, and it also made it illegal for other countries to produce or sell their own “tequila.”
