What is tequila?
Tequila is only made from the BLUE Agave (Ah-GAH-Vey) plant native to Mexico. Other liquors are made from other Agave plants but TRUE Tequila must come from BLUE agave.
And like Champagne - it MUST be made from plants grown in a very specific region of Mexico - that surrounding the city of Tequila, 65 km northwest of Guadalajara, and in the highlands (Los Altos) of the north western Mexican state of Jalisco.
Distilling Agave to make booze dates all the way back to the Aztecs - who called their version Pulque (POOL-kay). When the Spaniards turned up in 1521, they adopted the ancient Aztec drink and modified it using European distillation techniques and this has slowly evolved into the modern day drink we now know as Tequila.
