Which tequila category must mature for at least three years?

Extra añejo is the tequila category that must mature for at least three years.

Mexico introduced the extra añejo classification in 2006 to identify tequilas aged for three years or longer. These tequilas are commonly matured in oak, where they can develop deeper color and flavors influenced by the wood, spirit, and storage environment.

The category is distinct from añejo, which requires at least one year but less than three years of aging. Reposado occupies the shorter period of at least two months but less than one year, while blanco is usually unaged or only briefly rested.

Longer aging does not automatically mean a tequila is better for every drink. Barrel influence can make a spirit richer and softer, whereas blanco is often chosen when a cocktail or tasting aims to emphasize cooked-agave character.
