Tequila is a distilled spirit made from the blue agave cactus and originating in the Mexican city bearing its name. Tequila has four levels of quality and classification: silver – unaged, used in mixed drinks; gold – unaged, colored with caramelized sugar pulp; reposado – aged in oak barrels between 2 and 12 months, has a deeper complexity, color and smooth texture; and anejo (old) – aged in oak barrels between 18 and 36 months, with an even deeper color and flavor.
