- Class 1: Blanco, Silver, Plata is a white, transparent Tequila, which is bottled immediately after distillation.
- Class 2: Gold, Joven, Oro is a blend of white tequilas (class 3, 4 and 5) that have already matured. Up to 1% of the total amount can be added by sugar glaze, oak extract.
- Class 3: Aged, Reposado is a tequila aged in oak wood for at least 2 months.
- Class 4: Añejo is a tequila matured for at least 1 year in oak barrels and stored there for up to 3 years. The capacity of the barrels may not exceed 600 liters.
- Class 5: Ultra-Aged, Extra-Añejo is a tequila matured for at least 3 years.
