What is extra añejo tequila?
Extra añejo is the oldest official tequila classification, requiring at least three years in oak barrels of no more than 600 litres. It was formalised in 2006, long after añejo and reposado, and it remains the smallest category by volume because holding tequila in wood that long is expensive and evaporation is heavy in Jalisco's climate.
How long is Herradura Selección Suprema aged?
Forty-nine months in American white oak — just over four years, and well past the thirty-six months the extra añejo classification requires. The tequila is made at Casa Herradura in Amatitán from estate-grown Blue Weber agave, cooked in stone-and-brick ovens, fermented with airborne yeasts and twice distilled before it goes into barrel.
Was Herradura Selección Suprema the first extra añejo tequila?
It is widely credited as the first, including by the producer, and the timing supports it: Herradura introduced the expression in 1994, while the extra añejo classification itself was not formalised until 2006. So it was aged to extra añejo length more than a decade before the category existed to name it. Being first across an entire industry is difficult to prove outright, which is why this is an attribution rather than a settled fact.
