Tequila's precursor, a milky, frothy agave drink known as pulque, dates back to Mesoamerican times circa 1000 B.C. when indigenous Mexican tribes would commonly harvest and ferment it. It wouldn't be until 16th Century A.D., however, that the contemporary Tequila we know and love would be first produced, around a territory of land that wouldn't officially become known as Tequila until 1666.
That wouldn't stop Spanish aristocrats, Don Pedro Sánchez de Tagle, from opening the world's first tequila factory 66 years before Jalisco. In this Mexican state, the modern city of Tequila is located. It definitely wouldn't stop Don Jose Antonio de Cuervo from founding the first Vino Mezcal de Tequila de Jose Cuervo in Tequila over a century later in 1795, birthing the world's most successful tequila brand to this day.
Tequila's origins are relatively well documented, but unfortunately, the history of National Tequila Day's roots is a little murkier. Not much can be found on who originated the holiday, what originated the holiday, and why it takes place on the dates it does. Perhaps the originators imbibed a little too much on their supply to remember. Regardless, standard zeitgeist rules that National Tequila Day takes place on July 24th in the United States, and the Mexican Senate just ruled in 2018 that their own occurs on the third Saturday of every March.
