Tequila dates to approximately 1538, when the first agave fermentations began in the Jalisco region. With the arrival of Arab and Hispanic distillation techniques following the Spanish conquest, the drink evolved from pulque to mezcal and, finally, to what is known today as tequila. It was Don Cenobio Sauza, founder of Casa Sauza in 1873, who officially established the name "tequila" for the drink, definitively separating it from generic mezcal.
