Tequila is a distilled beverage made from the blue agave plant, which is native to Mexico. It has been produced since the 16th century in the region around the city of Tequila, Jalisco, Mexico. There are different types of tequila defined by aging processes - blanco is silver/unaged, reposado is aged 2-12 months in oak barrels, añejo is aged 1-3 years, and extra añejo is aged over 3 years. Mexico is the largest exporter of tequila, especially to the United States, and there are regulatory organizations that oversee tequila production and exports.
