The first “idea” of tequila can be dated back to an Aztec fermented drink known as “pulque”, which use the sap of the agave plant. This technique has a possibility of dating back even further, potentially around 1,000 B.C with the Olmecs. It wasn’t until the 1400s, when the Spanish invaded, that “mezcal” was created. All tequilas are technically mezcals, but not all mezcals are tequila. By early 1600s, the first large-scale distillery was created in what is now known as Tequila, Jalisco. The Cuervo family, yes as in THE Cuervo family, began commercially distilling what is viewed as modern tequila.
