Tequila that has been aged at least 12 months. Anejo is literally "old" in Spanish.

Tequila comes from the distillation of the blue agave cactus that grows in the town of Tequila in the state of Jalisco, Mexico.

Añejo tequilas must be allowed to mature for at least one year, and can be rested for up to ten years in rare cases. The Mexican government controls the tequilas tightly, and all aging is done in approved and sealed oak barrels. Color can also be added to anejo tequila, which is generally done with the addition of caramel (which also softens the flavour). All white, reposado and añejo tequilas are allowed to include demineralized water in order to bring the alcohol content in line with commercial allowances.
