For how long must aged Reposado tequila remain in oak casks?

The correct answer indicates that aged Reposado tequila must remain in oak casks for a period ranging from 2 to 12 months. This requirement is established by the regulatory standards governing the production of tequila, specifically within the categories designated by the Tequila Regulatory Council.

Reposado tequila is characterized by its aging process, which imparts distinct flavors and colors to the spirit due to the interaction with the wood of the casks. Aging in oak allows the tequila to develop a balance of the natural agave flavors with the elements introduced by the wood, such as vanilla, caramel, and spice notes.

The specified range ensures that Reposado tequila has enough time to mature and soften, creating a smooth drinking experience while still retaining some of the vibrant characteristics typical of younger tequilas. Ageing for shorter than 2 months would not qualify it as Reposado, while exceeding 12 months would classify the tequila into the Añejo category.
